Abstract

Size reduced textiles that are not densified are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The syngas quality, composition, and throughput are suitable for produce a wide range of chemicals.

POLYMERS. ARTICLES. AND CHEMICALS MADE FROM SIZE REDUCED

TEXTILE DERIVED SYNGAS

BACKGROUND

[0001] There is a well-known global issue with waste disposal, particularly of large volume consumer products such as textiles, size reduced textiles, and other polymers that are not considered biodegradable within acceptable temporal limits. There is a public desire to incorporate these types of wastes into new products through recycling, reuse, or otherwise reducing the amount of waste in circulation or in landfills.

[0002] A variety of means for the recycle, reuse, or reduction of waste stocks such as biomass, solid municipal waste, and paper have been articulated, among which is the gasification of such waste stocks. In such proposals, waste gasifiers, which are typically air supplied fluidized bed gasifiers that can readily accept a variety of component sizes and mixed stock types have been proposed or used. Such waste gasifiers typically operate at low to medium temperatures in the range of 500°C to 1000°C using air as an oxidizer, and given the lower operating temperature, incomplete oxidation reactions occur resulting in the generation of high quantities of residues that can appear in both the gas phase (syngas stream) and bottoms solid phase; e.g. tarry substances. The types of residues and their quantity will vary depending on the feedstock composition. Further, while waste gasifiers have the advantage of accepting highly variable sizes and compositions of feedstocks, the resulting syngas compositions are also widely variable over time, rendering them unusable for making chemicals without installation of expensive post treatments systems to clean up and purify the syngas streams existing the gasifier vessel. Even with purification processes, the

hydrogen/carbon monoxide/carbon dioxide ratios can remain highly variable. As a result of the expense to install systems to purify the syngas stream exiting the gasifier vessel to make it suitable for chemical synthesis, or their compositional variability, or their low throughput, or by reason of a combination of these factors, waste gasifier generated syngas streams are typically used to generate energy, e.g., steam or electricity or are used as fuel stocks.

[0003] Separated portions of mixed solid municipal wastes (MSW) have been investigated as a feed to a gasifier. MSW compositions contain a variety of solids, including bottles, sheets, films, paper, rubber, cardboard, cups, trays, wood, leather, textiles, glass, metal, etc. After separation of combustibles from non-combustibles (e.g. glass, metal, dirt), the mix of combustibles nevertheless remains highly variable in time from hour to hour, day to day, week to week, month to month, season to season, and by the source location. The variability lies both in form, e.g. bottles, garments, other textiles, personal care items, sheets, films, paper, cardboard, cups, trays, etc., and variability in compositional mix, e.g. polycarbonate, polyethylene, polypropylene, polyethylene terephthalate, polyamides, epoxy resins, acrylonitrilebutadiene, acrylics, alkyds, nylons, polyacetals, polystyrene, polyurethanes, vinyls, styrene acrylonitriles, ureas and melamines, wood, cellulosics, leather, food wastes, etc., variability in source location, and variability in the large variety of mechanical handling processes commercially practiced which employ different physical and chemical separation methods.

In fixed bed and fluidized bed gasifiers, this (source material variability) can result in an unacceptable syngas composition variability over time, particularly when the syngas is needed to synthesize chemicals which require a very consistent rate and quality of syngas or syngas ingredients.

[0004] Additionally, size reduced textiles and textiles have a fixed carbon content that is lower than fossil fuel sources such as coal or petcoke. As a result, size reduced textiles and textiles will combust and generate the syngas components at a more rapid rate than, for example, coal. Carbon monoxide generated from size reduced textiles or textiles will, therefore, have a longer residence time to convert to carbon dioxide under gasification conditions, relative to coal. While size reduced textiles and textiles have a high heat value (“HHV”), even in some cases equal to or exceeding coal, its use can also result in the generation of undesirable amounts of carbon dioxide in the raw syngas stream, particularly at high temperatures and pressures, along with a reduction in the amount of carbon monoxide that could have been produced by feeding only a fossil fuel. In addition, size reduced textiles and textiles have a higher hydrogen content than does, for example, fossil fuels, which can lead to the production of higher amounts of hydrogen in the raw syngas stream and affect the carbon monoxide/hydrogen ratio. These issues are not a concern when syngas is used for generating electricity or burned for heat value, but become a concern when making chemicals since the manufacture of chemicals relies on consistent output, ratio of carbon monoxide and/or hydrogen as raw materials for chemicals, and impurity types and profile in the syngas stream, particularly the lack of tarry residues or concentration of soot.

[0005] It is generally believed fixed bed waste gasifiers employed to accept combustible MSW streams are not an attractive alternative for generating a syngas stream for making chemicals for the reasons stated above. Many large-scale commercial gasifiers used to make pure consistent syngas streams at high output have a variety of constraints against accepting MSW or the components of MSW, such constraints depending on the type of gasifier employed. For example, entrained flow gasifiers employing feed injectors are not amenable to injecting textiles in the form found in MSW. The

configuration of updraft fixed bed or updraft moving bed gasifiers that have a countercurrent flow of gas through the bed make it difficult to handle fines.

For example, fine fibers introduced at the top of a fixed or moving downdraft gasifier may not uniformly settle onto the lower bed to form a fine char and gasify.

[0006] It would be desirable to incorporate textiles into a feedstock to a gasifier and producing a syngas stream suitable for making chemicals that does not have the drawbacks described above. SUMMARY

[0007] It would be desirable to employ a method for providing a circular life cycle of fibers in textiles that includes recycling post-consumer or post industrial textiles back to a molecular form suitable for making chemicals. It has been found that even if the textiles are reduced to a very small size, their variable composition between natural and synthetic fibers, and different types of synthetic fibers, can cause screening or filtration plugging if co-ground with other solid fuels, or may lead to unstable slurries. Further, textiles introduced into liquid or slurry fed gasifiers may not homogeneously disperse into the slurry, dispersion, or solution fed to the gasifier.

[0008] A method of gasification of a textile containing stream can be provided that would generate a syngas stream suitable for chemicals synthesis in which more complete conversion of waste feedstocks to syngas occurs to reduce the quantity of incomplete oxidation residues. It was also determined that it would be desirable to generate a syngas stream suitable for chemicals synthesis where at least a portion of a product (made from the syngas) is recycled to make raw materials fit for making the same types of products that were recycled and that there remains a need to continue the development of circularity in a variety of products.

[0009] In one aspect, a method is provided to incorporate recycle textiles into a gasifier feedstock to produce a size reduced textile derived syngas stream suitable for making chemicals. It would also be desirable to generate a size reduced textile derived syngas stream suitable for chemicals synthesis in which more carbon monoxide is formed in the size reduced textile derived syngas using feedstocks containing textiles relative to lower temperature and/or lower pressure MSW fed fixed bed waste gasifiers, and to reduce the quantity of incomplete oxidation residues (e.g. tar, char, etc.). In an aspect, a size reduced textile derived syngas stream output is generated from a gasifier vessel which is sufficiently compositionally consistent over time and suitable for making chemicals, and particularly without the need for blending syngas streams. In embodiments, the operations (described herein) are desirably conducted efficiently, in a stable manner, and on a commercial scale. From the size reduced textile derived syngas made by such a process, chemicals can be made which ultimately will form a raw material to make a variety of polymers or articles, including size reduced textile derived cellulose esters.

[0022] An example of a polymer or article that can be a candidate for accomplishing closed loop circularity is a size reduced textile derived cellulose ester and the fibers or other consumer products made from size reduced textile derived cellulose esters. Cellulose, one of the raw materials to make a size reduced textile derived cellulose ester, is a sustainable and renewable material in that it is obtained from plant material such as wood. However, the acyl groups attached to the cellulose backbone are generally made from intermediate chemicals derived fossil fuels (e.g., oil, natural gas, coal). The present invention offers a way to include both renewable and recycled content in size reduced textile derived cellulose esters by providing size reduced textile derived cellulose esters that are made from cellulose and organic compounds, e.g., acids or their anhydrides, derived from recycled, reused or other environmentally favored raw material.

DETAILED DESCRIPTION

[0028] Unless otherwise stated, reference the weight of the feedstock composition or stream includes all solids, and if present liquids, fed to the gasifier, and unless otherwise stated, does not include the weight of any gases in the feedstock composition as fed to the injector or gasifier.

[0029] Reference made throughout to a size reduced textile derived syngas, a size reduced textile derived chemical intermediate, size reduced textile derived cellulose ester reactants, size reduced textile derived cellulose ester polymers, their fibers, articles made from the fibers including nonwoven webs, yarns, cloth, fabric, and textiles includes, in each case, that at least a portion are size reduced textile derived.

[0030] By a“size reduced textile derived” gas, chemical compound, polymer, fiber, nonwoven web, sheet, film, textile, or any other product (collectively a“material”) is meant that at least a portion of the material finds its immediate source, or its ultimate source through one or more intermediate materials, from size reduced textiles that are gasified. The size reduced textiles that are gasified are not densified. Desirably, at least a portion of each gas, compound or reactant in a chain to make the material of interest finds at least a portion of its source in size reduced textiles that are gasified.

[0031] A PIA or PIA reactant or composition or compound is associated with, or originates from, a recycle textile, or size reduced textile derived syngas if any of them are subjected to partial oxidation gasification, regardless of when the allotment is taken, realized, or consumed. For example, a PIA can be associated with a size reduced textile that is gasified even though the allotment is taken and deposited into a recycle inventory or transferred to a PIA when recycle textiles are received or possessed or owned by a syngas manufacturer and even though the size reduced textile is not gasified at the time the allotment is taken. Further, an allotment that is associated with or originates from gasifying a size reduced textile does not limit the timing of taking or recognizing the allotment or depositing the allotment into a recycle inventory. An allotment taken when a recycle textile (textile or size reduced textile) is owned, possessed, or received by a syngas manufacturer and deposited into a recycle inventory is an allotment that is associated with or originates from gasifying a size reduced textile even though, at the time of taking or depositing the allotment, the size reduced textile has not yet been gasified.

[0032] As used throughout, the phrase“originates” or“origin” is

synonymous to“associated with.” [0033] By gasifying a size reduced textile in a gasifier that makes syngas of a quantity and quality suitable for making chemicals, a variety of chemicals and/or polymers can now be made containing the molecular components of the size reduced textile derived syngas.

[0034] There is now provided a size reduced textile derived cellulose ester reactant, a size reduced textile derived cellulose ester, a size reduced textile derived acetic acid, a size reduced textile derived acetic anhydride, a size reduced textile derived methanol, a size reduced textile derived methyl acetate, a size reduced textile derived cellulose ester fiber, a size reduced textile derived textile, and/or a size reduced textile derived nonwoven web.

[0035] As an example, reference is made to making a cellulose ester. In one embodiment or in combination with any of the mentioned embodiments, a size reduced textile derived cellulose ester composition is provided

comprising at least one size reduced textile derived cellulose ester having at least one substituent on an anhydroglucose unit (AU) derived from size reduced textile derived syngas.

[0036] In embodiments, the size reduced textile derived cellulose ester utilized in this invention can be any that is known in the art. Size reduced textile derived cellulose esters that can be used for the present invention generally comprise repeating units of the structure:

1 p q

wherein R , R , and R are selected independently from the group consisting of hydrogen or straight chain alkanoyl having from 2 to 10 carbon atoms. For size reduced textile derived cellulose esters, the substitution level is usually express in terms of degree of substitution (DS), which is the average number of non-OH substituents per anhydroglucose unit (AGU). Generally, conventional cellulose contains three hydroxyl groups in each AGU unit that can be substituted; therefore, DS can have a value between zero and three. However, low molecular weight cellulose mixed esters can have a total degree of substitution slightly above 3, due to end group contributions. Native cellulose is a large polysaccharide with a degree of polymerization from 250 - 5,000 even after pulping and purification, and thus the assumption that the maximum DS is 3.0 is approximately correct. However, as the degree of polymerization is lowered, as in low molecular weight cellulose mixed esters, the end groups of the polysaccharide backbone become relatively more significant, thereby resulting in a DS that can range in excess of 3.0. Low molecular weight cellulose mixed esters are discussed in more detail subsequently in this disclosure. Because DS is a statistical mean value, a value of 1 does not assure that every AGU has a single substituent. In some cases, there can be unsubstituted anhydroglucose units, some with two and some with three substituents, and typically the value will be a non-integer. Total DS is defined as the average number of all of substituents per anhydroglucose unit. The degree of substitution per AGU can also refer to a particular substituent, such as, for example, hydroxyl, acetyl, butyryl, or propionyl. In embodiments, the degree of polymerization for the cellulose ester is lower than that of the native cellulose. In embodiments, n is an integer in a range from 25 to 250, or 25 to 200, or 25 to 150, or 25 to 100, or 25 to 75.

[0037] In embodiments, the size reduced textile derived cellulose ester utilized can be a cellulose triester or a secondary size reduced textile derived cellulose ester. Examples of cellulose triesters include, but are not limited to, cellulose triacetate, cellulose tripropionate, or cellulose tributyrate. Examples of secondary size reduced textile derived cellulose esters include cellulose acetate, cellulose acetate propionate, and cellulose acetate butyrate.

[0038] In one embodiment or in combination with any of the mentioned embodiments, the size reduced textile derived cellulose ester can be chosen from cellulose acetate (CA), cellulose propionate (CP), cellulose butyrate (CB), cellulose acetate propionate (CAP), cellulose acetate butyrate (CAB), cellulose propionate butyrate (CPB), and the like, or combinations thereof. Examples of such size reduced textile derived cellulose esters are described in U.S. Pat. Nos. 1 ,698,049; 1 ,683,347; 1 ,880,808; 1 ,880,560; 1 ,984,147,

2,129,052; and 3,617,201 , incorporated herein by reference in their entirety to the extent that they do not contradict the statements herein.

[0039] In one embodiment or in combination with any of the mentioned embodiments, the size reduced textile derived cellulose esters have at least 2 anhydroglucose rings and can have between at least 50 and up to 5,000 anhydroglucose rings. The number of anhydroglucose units per molecule is defined as the degree of polymerization (DP) of the size reduced textile derived cellulose ester. In embodiments, size reduced textile derived cellulose esters can have an inherent viscosity (IV) of about 0.2 to about 3.0 deciliters/gram, or about 0.5 to about 1.8, or about 1 to about 1.5, as measured at a temperature of 25°C for a 0.25-gram sample in 100 ml of a 60/40 by weight solution of phenol/tetrachloroethane. Examples of size reduced textile derived cellulose esters include, but are not limited to, cellulose acetate, cellulose diacetate, cellulose propionate, cellulose butyrate, cellulose acetate propionate (CAP), cellulose acetate butyrate (CAB), cellulose propionate butyrate, and the like. In embodiments, size reduced textile derived cellulose esters useful herein can have a DS/AGU of about 2 to about 2.99, and the substituting ester can comprise acetyl, propionyl, butyryl, or any combinations of these. In another embodiment, the total DS/AGU ranges from about 2 to about 2.99 and the DS/AGU of acetyl ranges from about 0 to 2.2, with the remainder of the ester groups comprising propionyl, butyryl or combinations thereof.

[0040] Size reduced textile derived cellulose esters can be produced by any method known in the art. Examples of processes for producing size reduced textile derived cellulose esters are taught in Kirk-Othmer,

Encyclopedia of Chemical Technology, 5th Edition, Vol. 5, Wiley-lnterscience, New York (2004), pp. 394-444. Cellulose, the starting material for producing size reduced textile derived cellulose esters, can be obtained in different grades and sources such as from cotton linters, softwood pulp, hardwood pulp, corn fiber and other agricultural sources, and bacterial cellulose, among others.

[0041] One method of producing size reduced textile derived cellulose esters is esterification of the cellulose by mixing cellulose with the appropriate size reduced textile derived organic acids, size reduced textile derived acid anhydrides, and catalysts. Cellulose is then converted to a cellulose triester. Ester hydrolysis is then performed by adding a water-acid mixture to the cellulose triester, which can then be filtered to remove any gel particles or fibers. Water is then added to the mixture to precipitate the size reduced textile derived cellulose ester. The size reduced textile derived cellulose ester can then be washed with water to remove reaction by-products followed by dewatering and drying.

[0042] The cellulose triesters to be hydrolyzed can have three substituents selected independently from alkanoyls having from 2 to 10 carbon atoms. Examples of cellulose triesters include cellulose triacetate, cellulose tripropionate, and cellulose tributyrate or mixed triesters of cellulose such as cellulose acetate propionate, and cellulose acetate butyrate. These size reduced textile derived cellulose esters can be prepared by a number of methods known to those skilled in the art. For example, size reduced textile derived cellulose esters can be prepared by heterogeneous acylation of cellulose in a mixture of carboxylic acid and anhydride, at least one of which and at least a portion of which are a size reduced textile derived cellulose reactant, in the presence of a catalyst such as H2S04. Cellulose triesters can also be prepared by the homogeneous acylation of cellulose dissolved in an appropriate solvent such as LiCI/DMAc or LiCI/NMP.

[0043] Those skilled in the art will understand that the commercial term of cellulose triesters also encompasses size reduced textile derived cellulose esters that are not completely substituted with acyl groups. For example, cellulose triacetate commercially available from Eastman Chemical Company, Kingsport, TN, U.S.A., typically has a DS from about 2.85 to about 2.99.

[0044] After esterification of the cellulose to the triester, part of the acyl substituents can be removed by hydrolysis or by alcoholysis to give a secondary size reduced textile derived cellulose ester. As noted previously, depending on the particular method employed, the distribution of the acyl substituents can be random or non-random. Secondary size reduced textile derived cellulose esters can also be prepared directly with no hydrolysis by using a limiting amount of acylating reagent. This process is particularly useful when the reaction is conducted in a solvent that will dissolve cellulose. All of these methods yield size reduced textile derived cellulose esters that are useful in this invention.

[0045] In embodiments, the secondary size reduced textile derived cellulose esters useful in the present invention have an absolute weight average molecular weight (Mw) from about 5,000 to about 400,000 as measured by gel permeation chromatography (GPC) according to ASTM D6474. The following method is used to calculate the absolute weight average molecular weight values (Mw) for CE. The solvent is THF stabilized with BHT Preservative. The instrumentation for the THF/size reduced textile derived cellulose ester procedure consists of the following Agilent 1200 series components: degasser, isocratic pump, auto-sampler, column oven, UV/Vis detector and a refractive index detector. The test temperature is 30°C and flow rate is 1.0 ml/min. A sample solution of 25 mg size reduced textile derived cellulose ester in 10 ml TFIF with BFIT preservative and 10 pi toluene flow rate marker is made. The injection volume is 50 mI. The column set is Polymer Laboratories 5 miti PLgel, Guard + Mixed C + Oligopore. The detection is by refractive index. The calibrants are monodisperse polystyrene standards, Mw=580 to 3,220,000 from Polymer Laboratories. The universal calibration parameters are as follows: PS (K=0.0001280 and a=0.7120) and CE (K=0.00007572 and a=0.8424). The universal calibration parameters above were determined by light scattering and viscometery to yield the correct weight average molecular weights. In a further embodiment, the Mw is from about 15,000 to about 300,000. In yet further embodiments, the Mw ranges from about 10,000 to about 250,000; from about 15000 to 200000; from about 20,000 to about 150,000; from about 50,000 to about 150,000, or from about 70,000 to about 120,000.

[0046] The most common commercial secondary size reduced textile derived cellulose esters are prepared by initial acid catalyzed heterogeneous acylation of cellulose to form the cellulose triester. After a homogeneous solution in the corresponding carboxylic acid of the cellulose triester is obtained, the cellulose triester is then subjected to hydrolysis until the desired degree of substitution is obtained. After isolation, a random secondary size reduced textile derived cellulose ester is obtained. That is, the relative degree of substitution (RDS) at each hydroxyl is roughly equal.

[0047] The size reduced textile derived cellulose esters useful in the present invention can be prepared using techniques known in the art, and can be chosen from various types of size reduced textile derived cellulose esters, such as for example the size reduced textile derived cellulose esters that can be obtained from Eastman Chemical Company, Kingsport, TN, U.S.A., e.g., Eastman™ Cellulose Acetate Propionate CAP 482-20, Eastman™ Cellulose Acetate Propionate CAP 141 -20, Eastman™ Cellulose Acetate Butyrate CAB 381 -20, Cellulose Acetate Butyrate CAB 171 -15 and Eastman™ Cellulose Acetate CA 398-30.

[0048] In embodiments, the size reduced textile derived cellulose esters can contain chemical functionality and are described herein as either derivatized, modified, or functionalized size reduced textile derived cellulose esters. Functionalized size reduced textile derived cellulose esters can be produced by reacting the free hydroxyl groups of size reduced textile derived cellulose esters with a bifunctional reactant that has one linking group for grafting to the size reduced textile derived cellulose ester and one functional group to provide a new chemical group to the size reduced textile derived cellulose ester. Examples of such bifunctional reactants include succinic anhydride which links through an ester bond and provides acid functionality; mercaptosilanes which links through alkoxysilane bonds and provides mercapto functionality; and isocyanotoethyl methacrylate which links through a urethane bond and gives methacrylate functionality.

[0049] In embodiments, the size reduced textile derived cellulose esters can be prepared by converting cellulose to size reduced textile derived cellulose esters with reactants that are obtained, through one or more intermediate steps, from a size reduced textile derived syngas source. In embodiments, such reactants can be size reduced textile derived cellulose reactants that include organic acids and/or acid anhydrides, at least one of which is size reduced textile derived, used in the esterification or acylation reactions of the cellulose, e.g., as discussed herein.

[0050] By“size reduced textile derived syngas” is meant size reduced textile derived syngas obtained from a synthesis gas obtained by gasifying a fossil fuel source and a size reduced textile that is not densified, as described in the various embodiments more fully herein below. In embodiments, the feedstock (for the synthesis gas operation) can be in the form of a

combination of one or more particulated fossil fuel sources and size reduced plastics that are not densified.

[0051] Reference to the formation of a size reduced textile derived syngas, the manufacture and use of size reduced textile derived chemical

intermediates or size reduced textile derived cellulose reactants, means that a portion of such gas or chemicals are used to make chemicals or polymers.

For example, reference to the use of a size reduced textile derived cellulose ester reactant to make a size reduced textile derived cellulose ester does not imply that the entire amount of the reactant used to make the size reduced textile derived cellulose ester is derived from a textile, but rather that at least a portion of the batch or stream of the size reduced textile derived cellulose ester reactant contains a size reduced textile derived cellulose ester reactant, or put another way, at least a portion of the acyl groups on the size reduced textile derived cellulose ester were obtained from reactants, that through one or more intermediate steps, were obtained from a size reduced textile derived syngas.

[0052] In embodiments, the size reduced textile derived syngas is utilized to make at least one size reduced textile derived chemical intermediate in a reaction scheme to make a size reduced textile derived cellulose ester (CE intermediate). In embodiments, the size reduced textile derived syngas can be a component of feedstock (used to make at least one CE intermediate) that includes other sources of size reduced textile derived syngas, hydrogen, carbon monoxide, or combinations thereof. In embodiments, the only source of size reduced textile derived syngas used to make the CE intermediates is the size reduced textile derived syngas.

[0065] In aspects, an article is provided that comprises the size reduced textile derived cellulose ester compositions, as described herein. In

embodiments, the article is a textile fabric. In one embodiment or in

combination with any of the mentioned embodiments, the article is

biodegradable and/or compositable. In embodiments, a staple fiber is provided that comprises a size reduced textile derived cellulose ester composition that comprises cellulose acetate, as described herein.

[0066] In embodiments, the size reduced textile derived cellulose ester is biodegradable. In embodiments, the size reduced textile derived cellulose ester is biodegradable and contains content derived from a renewable source, e.g., cellulose from wood or cotton linter, and content derived from a recycled material source, e.g., size reduced textiles. Thus, in embodiments, a thermoplastic material is provided that is biodegradable and contains both renewable and recycled content, i.e., made from renewable and recycled sources.

[0067] In one aspect, the invention is directed to a fiber comprising at least one size reduced textile derived cellulose ester, as described herein. In embodiments, sheets, webs or fabrics are provided that comprise such fibers. In embodiments, the sheets, webs or fabrics can be woven or non-woven. In embodiments, the sheets, webs or fabrics can be wet laid or dry laid.

[0068] In embodiments, the invention is directed to a spun yarn that comprises at least one size reduced textile derived cellulose ester, as described herein. In embodiments, fibers comprising at least one size reduced textile derived cellulose ester can be prepared by spinning fibers.

The fibers can be spun as a continuous fiber or can be cut to a desired length.

[0069] In embodiments, the fibers, filaments, yarns and nonwoven fabrics can be made as described in WO2018/160588 A1 , published on September 7, 2018 (Applicant: Eastman Chemical Company), the contents of which is incorporated herein by reference, with the proviso that the fibers, filaments, yarns or nonwoven fabrics comprise at least one size reduced textile derived cellulose ester having size reduced textile content, as described more fully herein.

[0070] In embodiments, there is provided a textile fabric comprising fibers that comprise at least one size reduced textile derived cellulose ester, as described herein. In embodiments, the textile fabric can be prepared from fibers made with such size reduced textile derived cellulose esters. Such fibers can be used to make slivers, spun yarns, nonwoven webs, cloth, fabric, whether woven, knitted, or made from dry laid nonwovens. The fibers can be filaments or staple fibers.

[0071] It has been found that slivers can be successfully formed from CA staple fibers and further processed successfully to spun yarns to make textile fabric. CA staple fibers may be environmentally friendly, exhibit thermoplastic behavior, have a soft feel similar to that of cotton, and can be processed using both new and existing processing equipment. A CA staple fiber means a cellulose acetate staple fiber, and a“staple fiber” refers to a fiber cut from a continuous filament or tow band of continuous filaments. A carded sliver, spun yarn, or textile fabric“obtained from” a described element includes any number and type of intervening steps or process operations.

[0072] Staple fibers and filaments as described herein may be formed from one or more size reduced textile derived cellulose esters including, but not limited to, cellulose acetate, cellulose propionate, cellulose butyrate, cellulose acetate formate, cellulose acetate propionate, cellulose acetate butyrate, cellulose propionate butyrate, and mixtures thereof. Although described herein with reference to“cellulose acetate,” it should be understood that one or more of the above cellulose acid esters or mixed esters may also be used to form the fibers, nonwovens, and articles as described herein. Various types of size reduced textile derived cellulose esters are described, for example, in U.S. Patent Nos. 1 ,698,049; 1 ,683,347; 1 ,880,808; 1 ,880,560;

1 ,984,147, 2,129,052; and 3,617,201 , each of which is incorporated herein by reference to the extent not inconsistent with the present disclosure. In some cases, other types of treated or regenerated cellulose (e.g., viscose, rayon, or lyocell) may or may not be used in forming staple fibers as described herein.

[0073] When the staple fiber or filament is formed from cellulose acetate, it may be formed from cellulose diacetate, cellulose triacetate, or mixtures thereof. The cellulose acetate (or other size reduced textile derived cellulose ester) useful in embodiments of the present invention can have a degree of substitution in the range of from 1.9 to 2.9. As used herein, the term“degree of substitution” or“DS” refers to the average number of acyl substituents per anhydroglucose ring of the cellulose polymer, wherein the maximum degree of substitution is 3.0, as described above. In some cases, the cellulose acetate used to form fibers as described herein may have an average degree of substitution of at least about 1.95, 2.0, 2.05, 2.1 , 2.15, 2.2, 2.25, or 2.3 and/or not more than about 2.9, 2.85, 2.8, 2.75, 2.7, 2.65, 2.6, 2.55, 2.5, 2.45, 2.4, or 2.35, with greater than 90, 91 , 92, 93, 94, 95, 96, 97, 98, or 99 percent of the cellulose acetate having a degree of substitution greater than 2.15, 2.2, or 2.25. In some cases, greater than 90 percent of the cellulose acetate can have a degree of substitution greater than 2.2, 2.25, 2.3, or 2.35. Typically, acetyl groups can make up at least about 1 , 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, or 60 percent and/or not more than about 99, 95, 90, 85, 80, 75, or 70 percent of the total acyl substituents.

[0074] In embodiments, the cellulose acetate may have a weight-average molecular weight (Mw) of not more than 90,000, measured using gel permeation chromatography with N-methyl-2-pyrrolidone (NMP) as the solvent. In some cases, the cellulose acetate may have a molecular weight of at least about 10,000, at least about 20,000, 25,000, 30,000, 35,000, 40,000, or 45,000 and/or not more than about 100,000, 95,000, 90,000, 85,000, 80,000, 75,000, 70,000, 65,000, 60,000, or 50,000.

[0075] In embodiments, there is provided a staple fiber or filament formed from cellulose acetate, as described herein. In embodiments, the fiber is at least partially coated with at least one finish. In embodiments, the fiber has a denier per filament of less than about 3.0 and a crimp frequency of less than 22 crimps per inch (CPI). In embodiments, a plurality of the fibers exhibits a fiber-to-fiber staple pad coefficient of friction of not more than about 0.70.

[0076] In aspects, a carded nonwoven web or a carded sliver is provided comprising CA staple fibers that comprise cellulose acetate prepared according to the methods described herein. A carded sliver is a continuous bundle or strand of loose untwisted fibers that are aligned generally relatively parallel to each other. This alignment is conducted by subjecting the fibers to a carding process.

[0077] Other types of fibers suitable for use in a blend with size reduced textile derived cellulose ester staple fibers and filament can include natural and/or synthetic fibers including, but not limited to, cotton, rayon, viscose) or other types of regenerated cellulose such as Cupro, Tencel, Modal, and Lyocell cellulose, acetates such as polyvinylacetate, wool, glass, polyamides including nylon, polyesters such as polyethylene terephthalate (PET), polycyclohexylenedimethylene terephthalate (PCT) and other copolymers, olefinic polymers such as polypropylene and polyethylene, polycarbonates, poly sulfates, poly sulfones, polyethers, acrylics, acrylonitrile copolymers, polyvinylchloride (PVC), poly lactic acid, poly glycolic acid and combinations thereof.

[0078] In embodiments, the fibers, and yarns and nonwovens and cloths, fabrics and textiles formed therefrom can be biodegradable, meaning that such fibers are expected to decompose under certain environmental conditions. The degree of degradation can be characterized by the weight loss of a sample over a given period of exposure to certain environmental conditions. In some cases, the material used to form the staple fibers, the fibers, or the nonwoven webs or articles produced from the fibers can exhibit a weight loss of at least about 5, 10, 15, or 20 percent after burial in soil for 60 days and/or a weight loss of at least about 15, 20, 25, 30, or 35 percent after 15 days of exposure to a typical municipal composter. However, the rate of degradation may vary depending on the particular end use of the fibers, as well as the composition of the remaining article, and the specific test.

Exemplary test conditions are provided in U.S. Patent No. 5,970,988 and U.S. Patent No. 6,571 ,802.

[0079] In some embodiments, the size reduced textile derived cellulose ester fibers may be biodegradable fibers and such fibers may be used to form fibrous articles such as textiles, nonwoven fabrics, filters, and yarns. It has been found that size reduced textile derived cellulose ester fibers as described herein exhibit enhanced levels of environmental non-persistence, characterized by better-than-expected degradation under various

environmental conditions. Fibers and fibrous articles described herein may meet or exceed passing standards set by international test methods and authorities for industrial compostability, home compostability, and/or soil biodegradability.

[0080] To be considered“compostable,” a material must meet the following four criteria: (1 ) the material must be biodegradable; (2) the material must be disintegrable; (3) the material must not contain more than a maximum amount of heavy metals; and (4) the material must not be ecotoxic. As used herein, the term“biodegradable” generally refers to the tendency of a material to chemically decompose under certain environmental conditions.

Biodegradability is an intrinsic property of the material itself, and the material can exhibit different degrees of biodegradability, depending on the specific conditions to which it is exposed. The term“disintegrable” refers to the tendency of a material to physically decompose into smaller fragments when exposed to certain conditions. Disintegration depends both on the material itself, as well as the physical size and configuration of the article being tested. Ecotoxicity measures the impact of the material on plant life, and the heavy metal content of the material is determined according to the procedures laid out in the standard test method.

[0081] The size reduced textile derived cellulose ester fibers can exhibit a biodegradation of at least 70 percent in a period of not more than 50 days, when tested under aerobic composting conditions at ambient temperature (28°C ± 2°C) according to ISO 14855-1 (2012). In some cases, the size reduced textile derived cellulose ester fibers can exhibit a biodegradation of at least 70 percent in a period of not more than 49, 48, 47, 46, 45, 44, 43, 42,

41 , 40, 39, 38, or 37 days when tested under these conditions, also called “home composting conditions.” These conditions may not be aqueous or anaerobic. In some cases, the size reduced textile derived cellulose ester fibers can exhibit a total biodegradation of at least about 71 , 72, 73, 74, 75,

76, 77, 78, 79, 80, 81 , 82, 83, 84, 85, 86, 87, or 88 percent, when tested under according to ISO 14855-1 (2012) for a period of 50 days under home composting conditions. This may represent a relative biodegradation of at least about 95, 97, 99, 100, 101 , 102, or 103 percent, when compared to cellulose subjected to identical test conditions.

[0082] To be considered“biodegradable,” under home composting conditions according to the French norm NF T 51 -800 and the Australian standard AS 5810, a material must exhibit a biodegradation of at least 90 percent in total (e.g., as compared to the initial sample), or a biodegradation of at least 90 percent of the maximum degradation of a suitable reference material after a plateau has been reached for both the reference and test item. The maximum test duration for biodegradation under home compositing conditions is 1 year. The size reduced textile derived cellulose ester fibers as described herein may exhibit a biodegradation of at least 90 percent within not more than 1 year, measured according 14855-1 (2012) under home

composting conditions. In some cases, the size reduced textile derived cellulose ester fibers may exhibit a biodegradation of at least about 91 , 92, 93, 94, 95, 96, 97, 98, 99, or 99.5 percent within not more than 1 year, or the fibers may exhibit 100 percent biodegradation within not more than 1 year, measured according 14855-1 (2012) under home composting conditions.

[0083] Additionally, or in the alternative, the fibers described herein may exhibit a biodegradation of at least 90 percent within not more than about 350, 325, 300, 275, 250, 225, 220, 210, 200, 190, 180, 170, 160, 150, 140, 130,

120, 1 10, 100, 90, 80, 70, 60, or 50 days, measured according 14855-1 (2012) under home composting conditions. In some cases, the fibers can be at least about 97, 98, 99, or 99.5 percent biodegradable within not more than about 70, 65, 60, or 50 days of testing according to ISO 14855-1 (2012) under home composting conditions. As a result, the size reduced textile derived cellulose ester fibers may be considered biodegradable according to, for example, French Standard NF T 51 -800 and Australian Standard AS 5810 when tested under home composting conditions.

[0084] The size reduced textile derived cellulose ester fibers can exhibit a biodegradation of at least 60 percent in a period of not more than 45 days, when tested under aerobic composting conditions at a temperature of 58°C (± 2°C) according to ISO 14855-1 (2012). In some cases, the fibers can exhibit a biodegradation of at least 60 percent in a period of not more than 44, 43, 42, 41 , 40, 39, 38, 37, 36, 35, 34, 33, 32, 31 , 30, 29, 28, or 27 days when tested under these conditions, also called“industrial composting conditions.” These may not be aqueous or anaerobic conditions. In some cases, the fibers can exhibit a total biodegradation of at least about 65, 70, 75, 80, 85, 87, 88, 89, 90, 91 , 92, 93, 94, or 95 percent, when tested under according to ISO 14855- 1 (2012) for a period of 45 days under industrial composting conditions. This may represent a relative biodegradation of at least about 95, 97, 99, 100, 102, 105, 107, 1 10, 1 12, 1 15, 1 17, or 1 19 percent, when compared to cellulose fibers subjected to identical test conditions.

[0085] To be considered“biodegradable,” under industrial composting conditions according to ASTM D6400 and ISO 17088, at least 90 percent of the organic carbon in the whole item (or for each constituent present in an amount of more than 1 % by dry mass) must be converted to carbon dioxide by the end of the test period when compared to the control or in absolute. According to European standard ED 13432 (2000), a material must exhibit a biodegradation of at least 90 percent in total, or a biodegradation of at least 90 percent of the maximum degradation of a suitable reference material after a plateau has been reached for both the reference and test item. The maximum test duration for biodegradability under industrial compositing conditions is 180 days. The size reduced textile derived cellulose ester fibers described herein may exhibit a biodegradation of at least 90 percent within not more than 180 days, measured according 14855-1 (2012) under industrial composting conditions. In some cases, the size reduced textile derived cellulose ester fibers may exhibit a biodegradation of at least about 91 , 92, 93, 94, 95, 96, 97, 98, 99, or 99.5 percent within not more than 180 days, or the fibers may exhibit 100 percent biodegradation within not more than 180 days, measured according 14855-1 (2012) under industrial composting conditions.

[0086] Additionally, or in the alternative, size reduced textile derived cellulose ester fibers described herein may exhibit a biodegradation of least 90 percent within not more than about 175, 170, 165, 160, 155, 150, 145, 140, 135, 130, 125, 120, 1 15, 1 10, 105, 100, 95, 90, 85, 80, 75, 70, 65, 60, 55, 50, or 45 days, measured according 14855-1 (2012) under industrial composting conditions. In some cases, the size reduced textile derived cellulose ester fibers can be at least about 97, 98, 99, or 99.5 percent biodegradable within not more than about 65, 60, 55, 50, or 45 days of testing according to ISO 14855-1 (2012) under industrial composting conditions. As a result, the size reduced textile derived cellulose ester fibers described herein may be considered biodegradable according ASTM D6400 and ISO 17088 when tested under industrial composting conditions.

[0087] The fibers or fibrous articles may exhibit a biodegradation in soil of at least 60 percent within not more than 130 days, measured according to ISO 17556 (2012) under aerobic conditions at ambient temperature. In some cases, the fibers can exhibit a biodegradation of at least 60 percent in a period of not more than 130, 120, 1 10, 100, 90, 80, or 75 days when tested under these conditions, also called“soil composting conditions.” These may not be aqueous or anaerobic conditions.

[0095] In embodiments, cellulose acetate fibers are provided that comprise size reduced textile content and are biodegradable and/or compostable. It is believed that the cellulose acetate fibers can achieve higher levels of biodegradability and/or compostability without use of additives that have traditionally been used to facilitate environmental non-persistence of similar fibers. Such additives can include, for example, photodegradation agents, biodegradation agents, decomposition accelerating agents, and various types of other additives. Despite being substantially free of these types of additives, In embodiments, the cellulose acetate fibers and articles can be provided that exhibit enhanced biodegradability and compostability when tested under industrial, home, and/or soil conditions, as discussed herein.

[0096] In some embodiments, the cellulose acetate fibers described herein may be substantially free of photodegradation agents. For example, the fibers may include not more than about 1 , 0.75, 0.50, 0.25, 0.10, 0.05, 0.025, 0.01 , 0.005, 0.0025, or 0.001 weight percent of photodegradation agent, based on the total weight of the fiber, or the fibers may include no photodegradation agents. Examples of such photodegradation agents include, but are not limited to, pigments which act as photooxidation catalysts and are optionally augmented by the presence of one or more metal salts, oxidizable promoters, and combinations thereof.

[0100] In embodiments, durable articles are provided that comprise the size reduced textile derived cellulose esters, as described herein. In embodiments, the durable articles are made from moldable thermoplastic material comprising the size reduced textile derived cellulose esters, as described herein. In embodiments, the moldable thermoplastic material comprises size reduced textile derived cellulose esters chosen from cellulose acetate propionate, cellulose acetate butyrate, or combinations thereof.

[0101] In one embodiment or in combination with any of the mentioned embodiments, an integrated process for preparing a size reduced textile derived cellulose ester is provide which comprises the processing steps of:

(1 ) preparing a size reduced textile derived syngas obtained by gasifying a fossil fuel source and size reduced textiles; (2) preparing at least one size reduced textile derived chemical intermediate from said size reduced textile derived syngas; (3) reacting said size reduced textile derived chemical intermediate in a reaction scheme to prepare at least one size reduced textile derived cellulose reactant for preparing a size reduced textile derived cellulose ester, and/or selecting said size reduced textile derived chemical intermediate to be at least one size reduced textile derived cellulose reactant for preparing a size reduced textile derived cellulose ester; and (4) reacting said at least one size reduced textile derived cellulose reactant to prepare said size reduced textile derived cellulose ester; wherein said size reduced textile derived cellulose ester comprises at least one substituent on an anhydroglucose unit (AGU) derived from size reduced textile derived syngas.

[0102] In embodiments, the processing steps (1 ) to (4) are carried out in a system that is in fluid and/or gaseous communication (i.e., including the possibility of a combination of fluid and gaseous communication). It should be understood that the size reduced textile derived chemical intermediates, in one or more of the reaction schemes for producing size reduced textile derived cellulose esters starting from size reduced textile derived syngas, may be temporarily stored in storage vessels and later reintroduced to the integrated process system, or at time are sealed off through valves, and are nevertheless considered to be in fluid communication upstream and downstream. Further, the entire process need not be in gaseous and/or fluid communication simultaneously to be considered in gaseous communication provided that piping can be traced from one vessel to another to close the loop.

[0103] In embodiments, the at least one size reduced textile derived chemical intermediate is chosen from methanol, methyl acetate, acetic anhydride, acetic acid, or combinations thereof. In one embodiment or in combination with any of the mentioned embodiments, one size reduced textile derived chemical intermediate is methanol, and the methanol is used in a reaction scheme to make a second size reduced textile derived chemical intermediate that is acetic anhydride. In embodiments, the size reduced textile derived cellulose reactant is acetic anhydride.

[0104] Turning to the gasification process, for purposes of classifying materials in the feedstock stream or composition, a solid fossil fuel used can be coal, petcoke, or any other solid at 25°C and 1 atmosphere that is a byproduct from refining oil or petroleum. The fossil fuel portion of the feedstock composition is to be distinguished from size reduced textiles, even if the size reduced textiles are carbonaceous and in part derived from raw materials obtained from refining crude oil. A fossil fuel can include liquid fossil fuels, such as liquid hydrocarbons or streams obtained from refining crude oil, or waste streams from chemical synthetic processes.

[0105] Generally, in a synthesis gas operation one or more feedstock composition(s) comprised of fossil fuel sources (e.g. coal, petcoke, liquid hydrocarbons) and size reduced textiles as an individual stream or combined with the fossil fuel source streams, and optionally water and other chemical additives, are fed or injected along with an oxidizer gas into a gasification reaction zone or chamber of a synthesis gas generator (gasifier) and gasified in the presence of an oxidizer such as oxygen, also fed to the gasifier. A hot gas stream is produced in the gasification zone, optionally refractory lined, at high temperature and high pressure generating a molten slag, soot, ash and gases including hydrogen, carbon monoxide, carbon dioxide and can include other gases such as methane, hydrogen sulfide and nitrogen depending on the fuel source and reaction conditions. The hot gas stream is produced in the reaction zone is cooled using a syngas cooler or in a quench water bath at the base of the gasifier which also solidifies ash and slag and separates solids from the gases. The quench water bath also acts as a seal to maintain the internal temperature and pressure in the gasifier while the slag, soot and ash are removed into a lock hopper. The cooled product gas stream removed from the gasifier (the raw size reduced textile derived syngas stream) can be further treated with water to remove remaining solids such as soot, and then further treated to remove acid gas (e.g. hydrogen sulfide) after optionally further cooling and shifting the ratio of carbon monoxide to hydrogen.

[0111] Natural fibers include those that are plant derived or animal derived. Natural fibers can be cellulosics, hemicellulosics, and lignins. Examples of plant derived natural fibers include hardwood pulp, softwood pulp, and wood flour; and other plant fibers including those in wheat straw, rice straw, abaca, coir, cotton, flax, hemp, jute, bagasse, kapok, papyrus, ramie, rattan, vine, kenaf, abaca, henequen, sisal, soy, cereal straw, bamboo, reeds, esparto grass, bagasse, Sabai grass, milkweed floss fibers, pineapple leaf fibers, switch grass, lignin-containing plants, and the like. Examples of animal derived fibers include wool, silk, mohair, cashmere, goat hair, horsehair, avian fibers, camel hair, angora wool, and alpaca wool.

[0112] Synthetic fibers are those fibers that are, at least in part,

synthesized or derivatized through chemical reactions, or regenerated, and include, but are not limited to, rayon, viscose, mercerized fibers or other types of regenerated cellulose (conversion of natural cellulose to a soluble cellulosic derivative and subsequent regeneration) such as lyocell (also known as Tencel), Cupro, Modal, acetates such as polyvinylacetate, polyamides including nylon, polyesters such as those polyethylene terephthalate (PET), copolyesters including those made with IPA, CHDM and/or 2, 2,4,4- tetramethyl-1 ,3-cyclobutanediol, polycyclohexylenedimethylene terephthalate (PCT) and other copolymers, olefinic polymers such as polypropylene and polyethylene, polycarbonates, poly sulfates, poly sulfones, polyethers such as polyether-urea known as Spandex or elastane, polyacrylates, acrylonitrile copolymers, polyvinylchloride (PVC), polylactic acid, polyglycolic acid, sulfopolyester fibers, and combinations thereof.

[0113] The size reduced textiles are obtained from post-consumer textiles and/or post-industrial textiles (also commonly known as pre-consumer textiles). Post-consumer textiles are those that have been used at least once for its intended application for any duration of time regardless of wear. Post industrial size reduced textiles include rework, regrind, scrap, trim, out of specification textiles (e.g. fibers, yarns, webs, cloths, fabrics, finished textiles) that have not been used for their intended application, or any textiles that have not been used by the end consumer.

[0114] The form of the textiles useful to make size reduced textiles are not limited, and can include any of the forms of articles or materials used to make textiles described above; e.g. fibers, yarns, fabrics, cloths, finished article forms, or pieces thereof. The size reduced textiles can be of varying age and composition.

[0115] The source of the post-consumer or post-industrial textiles (also known as pre-consumer) is not limited, and can include textiles present in and separated from municipal solid waste streams (“MSW”). For example, an MSW stream can be processed and sorted to several discrete components, including textiles, fibers, papers, wood, glass, metals, etc. Other sources of textiles include those obtained by collection agencies, or by or for or on behalf of textile brand owners or consortiums or organizations, or from brokers, or from postindustrial sources such as scrap from mills or commercial production facilities, unsold fabrics from wholesalers or dealers, from mechanical and/or chemical sorting or separation facilities, from landfills, or stranded on docks or ships.

[0116] In one embodiment, the textiles used to make the size reduced textiles are within one of the components or streams that are separated from an MSW source. [0117] The size reduced textiles are fed as a fuel for gasification, or to a gasifier neat, or slurried and fed to a gasifier.

[0118] To obtain the size reduced textiles, the textiles are reduced in size by any means, including by chopping, grinding, shredding, harrowing, confrication, pulverizing, or cutting a feed of textiles to make size reduced textiles. Optionally, the size reduced textiles can continue to be ground, comminuted, pulverized or otherwise size reduced to obtain the desired average particle size if one desires to obtain finer particles. The form of the size reduced textiles will depend on the desired method of densification. For example, the size reduced textiles can be in the form of coarse or fine particles, even a powder (of any shape other than the original shape of the textile feed). Alternatively, the size reduced textiles can be in the form of a viscous mass that does not have discrete particles. Fluidized bed granulators can be used, optionally with a drying gas, as well as tumbling granulators of disc or drum design connected to high speed mixers having cutting blades on a horizonal or vertical shaft. Examples of different kinds of suitable size reducing processes and equipment as stand-alone or coupled together include air swept mills, knife cutting, fine grinders that can have multiple grinding zones with internal classification systems, choppers with finer knives at the end, disintegrators that can handle shredding of textiles even high moisture feeds and then optional fine cutting or milling into smaller size such as a powder, high speed cutting blades that can have multiple zones for moving coarser material to finer material. The size reducing equipment can also include drying before cutting or simultaneous with drying

[0119] Size reduced textiles are any textiles which have been subjected to a process of cutting, shredding, pulverizing, chopping, or other means to reduce the size of textile from one size to a smaller size.

[0120] In embodiments, at least 20%, or at least 30%, or at least 50%, or at least 75%, or at least 80%, or at least 90%, or at least 95%, or at least 98% of the fibers in the textiles feedstock have an aspect ratio L:D of at least 1.5:1 , or at least 1.75:1 , or at least 2:1 , or at least 2.25:1 , or at least 2.5:1 , or at least 2.75:1 , or at least 3:1 , or at least 3.25:1 , or at least 3.5:1 , or at least 3.75:1 , or at least 4:1 , or at least 4.5:1 , or at least 5:1 , or at least 5.5:1 , or at least 6:1.

[0121] The polymers, intermediates, and articles such as fibers and textiles having a recycle content are broadly named as Recycle PIA (recycle polymers, intermediates or articles). The polymers, intermediates and articles are as described throughout this description. Recycle PIA can be obtained in a reaction scheme as described herein, or can be obtained by way of a recycle content allotment, provided that the allotment has its origin in, or withdrawn from an inventory of allotments containing at least one allotment having its origin in, gasifying a feedstock containing a fossil fuel and size reduced textiles. The“recycle content allotment” is a recycle content value that is transferred from an originating composition, compound or polymer at least a portion of which is obtained by or with the gasification of feedstock a feedstock containing a fossil fuel and size reduced textiles, to a receiving composition, compound, or polymer (referred to herein as a“composition” for brevity) receiving the allotment.

[0122] There is also provided a circular manufacturing process comprising:

1. providing a recycle textile, and

2. size reducing said recycle textile to form a size reduced textile, and

3. gasifying said size reduced textile to produce a size reduced textile derived syngas, and

(i) reacting said size reduced textile derived syngas to make a recycle content intermediate, polymer, or article (Recycle PIA) each of which have their origin at least in part to said size reduced textile derived syngas or

(ii) assigning a recycle content allotment, obtained from said recycle textile, to an intermediate, polymer, or article to produce a Recycle PIA; and

4. optionally, taking back at least a portion of said Recycle PIA as a feedstock to said gasification process step (i), or (ii), or (iii). [0123] In the above described process, an entirely circular or closed loop process is provided in which textiles can be recycled multiple times to make the same family or classification of textiles.

[0124] Examples of articles that are included in PIA are fibers, yarns, tow, continuous filaments, staple fibers, rovings, fabrics, textiles, flake, sheet, compounded sheet, and consumer articles.

[0125] In this or in combination with any of the mentioned embodiments, the allotment can be assigned to an intermediate, polymer, or article to produce a Recycle PIA directly from a recycle content value taken from the recycle textile or size reduced textile or from the step of gasifying a feedstock containing a fossil fuel and size reduced textile, or the allotment can be assigned to the intermediate, polymer, or article to product a recycle PIA indirectly by assigning the recycle content value taken from a recycle inventory into which recycle content value is deposited from the recycle content present in the recycle textile or in the size reduced textile or the step of gasifying a feedstock containing a fossil fuel and size reduced textile.

[0126] In one embodiment, the Recycle PIA is a polymer or article (e.g. fiber) of the same family or classification of polymers or articles (e.g. fibers) contained in or one the recycle textile used in step (i).

[0127] In one embodiment, a Recycle PIA can be made by a process in which size reduced textiles are gasified according to any of the processes described herein.

[0128] There is also provided a circular manufacturing process comprising:

1. A manufacturer of syngas, or one among its Family of Entities, or an entity contracted with either of them (collectively the “Recipient”), receiving recycle textiles (whether postindustrial or post-consumer), optionally and desirably from an industrial supplier of said articles (e.g. textiles) or fibers contained in or on said textile, and

2. One or more of the Recipients size reducing said textile or fibers to make a sized reduced textile, and 3. One or more of the Recipients gasifying said size reduced textile to produce a size reduced textile derived syngas, and

4. either

(i) reacting said size reduced textile derived syngas to make a recycle content intermediate, polymer, or article

(Recycle PIA) each of which have their origin at least in part to said size reduced textile derived syngas or

(ii) assigning a recycle content allotment, obtained from said recycle textile or said size reduced textile, to an intermediate, polymer, or article to thereby produce a Recycle PIA; and

5. optionally, furnishing at least a portion of said Recycle PIA to said industrial supplier, or to an entity contracted with said industrial supplier or with one among the Family of Entities of the industrial supplier for the supply of said Recycle PIA or an article made with said Recycle PIA.

[0129] In embodiments, the allotment can be assigned to an intermediate, polymer, or article to produce a Recycle PIA directly from a recycle content value taken from the recycle textile or size reduced textiles or from the step of gasifying a feedstock containing a fossil fuel and recycle textiles or size reduced textiles, or the allotment can be assigned to the intermediate, polymer, or article to product a recycle PIA indirectly by assigning the recycle content value taken from a recycle inventory into which recycle content value is deposited from the recycle content present in the recycle textile or in the size reduced textiles or the step of gasifying a feedstock containing a fossil fuel and size reduced textiles.

[0130] In the above described process, an entirely circular or closed loop process is provided in which textiles can be recycled multiple times to make the same family or classification of textiles. The industrial supplier may furnish a processor entity with the textile or articles containing the textile to process those textiles or articles into a form suitable or more suitable for gasification as further described herein to make size reduced textiles, and in turn, the processor entity supplies the size reduced textiles to the

manufacturer of syngas or one among its Family of Entities who can either feed to size reduced textiles as such to a feedstock stream to a gasifier, or can further process the size reduced textiles into a final size suitable for gasification by any suitable process, such as pulverization or grinding. The gasification processes, equipment, and designs used can be any of those mentioned herein. The size reduced textile derived syngas made using feedstocks containing the size reduced textiles can then either by converted through a reaction scheme to make Recycle PIA, or the allotments created by such gasification step or obtained from the recycle textiles or size reduced textiles can be stored in an inventory of allotments, and from the inventory of allotments from any source, a portion thereof can be withdrawn and assigned to an intermediate, polymer or article to make Recycle PIA. To close the circularity of the textile, at least a portion of the Recycle PIA can by furnished to the supplier of the textiles, or it can be supplied to any entity contracted with the supplier to process the Recycle PIA into a different form, different size, or to combine with other ingredients or textiles (e.g. compounders and/or sheet extruders), or to make articles containing the PIA, for supply to or on behalf of the supplier. The Recycle PIA furnished to the industrial supplier or one of its contracted entities is desirably in the same family or type of textile as the textile or article containing the textile was supplied by the industrial supplier to the Recipient.

[0131] A“recycle content allotment” or“allotment” means a recycle content value that is:

a. transferred from a recycle waste (which is any recycle waste stream whether or not it contains recycle textiles) to a receiving composition (e.g., compound, polymer, article, intermediate, feedstock, product, or stream) that may or may not have a physical component that is traceable to the recycle waste; or b. deposited into a recycle inventory at least a portion of which originates from recycle textiles or size reduced textiles or their gasification.

[0132] An allotment can be an allocation or a credit. A recycle waste is any one of waste streams identified throughout this disclosure, including the size reduced textiles, the textiles from which they originate, or the feedstock composition containing the size reduced textiles.

[0133] A“recycle content value” is a unit of measure representative of a quantity of material having its origin in recycle textile or size reduced textiles. The recycle content value can have its origin in any type of recycled textile or any recycle textile processed in any type of process before being gasified.

[0134] The particular recycle content value can be determined by a mass balance approach or a mass ratio or percentage or any other unit of measure and can be determined according to any system for tracking, allocating, and/or crediting recycle content among various compositions. A recycle content value can be deducted from a recycle inventory and applied to a product or composition to attribute recycle content to the product or

composition. A recycle content value does not have to originate from gasifying recycle textile, and can be a unit of measure having its known or unknown origin in any technology used to process recycle textile. In one embodiment, at least a portion of the recycle textiles from which an allotment is obtained is also gasified as described throughout the one or more embodiments herein; e.g. combined with a fossil fuel and subjected to gasification.

[0135] In one embodiment, at least a portion of the recycle content allotment or allotment or recycle value deposited into a recycle content inventory is obtained from recycle textile or size reduced textiles. Desirably, at least 60%, or at least 70%, or at least 80%, or at least 90% or at least 95%, or up to 100% of the:

a. allotments or

b. deposits into the recycle inventory, or c. recycle content value in the recycle inventory, or

d. recycle content value applied to compositions to make Recycle PIA

are obtained from recycle textile or size reduced textiles.

[0136] A recycle content allotment can include an allocation or a credit obtained with the transfer or use of a raw material. In embodiments, the polymer, intermediate, composition, article or stream receiving the recycle content allotment can be or contain a portion of a non-recycle composition (e.g., compound, polymer, feedstock, product or stream). “Non-recycle” means a composition, compound or polymer none of which was directly or indirectly derived from a size reduced textile derived syngas. As used herein, a“non-recycle feed” in the context of a feed to the gasifier means a feed that does not contain a recycle waste stream of any kind. Once a non-recycle feed, composition, compound, polymer, or article obtains a recycle content allotment (e.g. either through a credit or allocation), it becomes a recycle content feed, composition, compound, polymer or article, or in this case, a Recycle PIA.

[0137] As used herein, the term“recycle content allocation” is a type of recycle content allotment, where the entity or person supplying the

composition sells or transfers the composition to the receiving person or entity, and the person or entity that made the composition has an allotment at least a portion of which can be associated with the composition sold or transferred by the supplying person or entity to the receiving person or entity. The supplying entity or person(s) can be controlled by the same entity or a variety of affiliates that are ultimately controlled or owned at least in part by a parent entity (“Family of Entities”), or they can be from a different Family of Entities. Generally, a recycle content allocation travels with a composition and with the downstream derivates of the composition. An allocation may be deposited into a recycle inventory and withdrawn from the recycle inventory as an allocation and applied to a composition to make a Recycle PIA. [0138] A“recycle content credit” and“credit” means a type of recycle content allotment and may or may not contain a physical component that is traceable to sized reduced textile derived syngas. For example, the (i) manufacturer of the product can operate within a legal framework, or an association framework, or an industry recognized framework for making a claim to a recycle content through, for example, a system of credits

transferred to the product manufacturer regardless of where or from whom the size reduced textile derived syngas, or downstream products made thereby, or reactant feedstocks to make the polymer and/or article, is purchased or transferred, or (ii) a supplier of the size reduced textile derived syngas stream or downstream products made thereby (“supplier”) operates within an allocation framework that allows for allocating a recycle content value to a portion or all of the size reduced textile derived syngas stream or

downstream products made thereby and to transfer the allotment to the manufacturer of the product or any intermediary who obtains a supply of size reduced textile derived syngas stream or a downstream product thereof, from the supplier.

[0139] In embodiments, a credit is available for sale or transfer or use, or is sold or transferred or used, either:

a. without the sale of a composition, or

b. with the sale or transfer of a composition but the allotment is not associated the sale or transfer of the composition, or c. is deposited into or withdrawn from a recycle inventory that does not track the molecules of a recycle content feedstock to the molecules of the resulting compositions which were made with the recycle content feedstocks, or which does have such tracking capability but which did not track the particular allotment as applied to a composition.

[0140] In embodiments, an allotment may be deposited into a recycle inventory, and a credit may be withdrawn from the inventory and applied to a composition to make a Recycle PIA. This would be the case where an allotment is created from a recycle textile and deposited into a recycle inventory, and deducting a recycle content value from the recycle inventory and applying it to a composition to make a Recycle PIA that either has no portion originating from syngas or does have a portion originating from syngas but such syngas making up the portion of the composition was not a size reduced textile derived syngas. In this system, one need not trace the source of a reactant compound or composition back to the manufacture of size reduced textile derived syngas stream or back to any atoms contained in the size reduced textile derived syngas stream, but rather can use any reactant compound of composition made by any process and have associated with such reactant compound or composition, or have associated with the Recycle PIA, a recycle content allotment. In an embodiment, the Recycle PIA reactants (i.e., the compositions used to make Recycle PIA or the

compositions to which an allotment is applied) do not contain recycle content.

[0141] In one embodiment, the composition receiving an allotment to make a Recycle PIA originates in part from a syngas stream obtained by any gasification process. The feedstock to the gasification process may optionally contain fossil fuel such as coal. The feedstock may optionally also contain a combination of fossil fuel and recycle textiles or size reduced textiles. In one embodiment, there is provided a process in which:

a. a recycle textile is obtained,

b. a recycle content value (or allotment) is obtained from the

recycle textile and

i. deposited into a recycle inventory, and an allotment (or credit) is withdrawn from the recycle inventory and applied to a composition to obtain a Recycle PIA, or

ii. applied to a composition to obtain a Recycle PIA; and c. at least a portion of the recycle textile is subjected to a

gasification process, optionally by combining it with a fossil fuel as a feedstock to a gasifier, optionally according to any of the designs or processes described herein; and d. optionally at least a portion of the composition in step b.

originates from a syngas stream, optionally the syngas stream having been obtained by any of the feedstocks and methods described herein.

[0142] The steps b. and c. do not have to occur simultaneously. In one embodiment, they occur within a year of each other, or within six (6) months of each other, or within three (3) months of each other, or within one (1 ) month of each other, or within two (2) weeks of each other, or within one (1 ) week of each other, or within three (3) days of each other. The process allows for a time lapse between the time an entity or person receiving the recycle textile and creating the allotment (which can occur upon receipt or ownership of the recycle textile) and the actual processing of the recycle textile in a gasifier.

[0143] As used herein,“recycle inventory” and“inventory” mean a group or collection of allotments (allocations or credits) from which deposits and deductions of allotments in any units can be tracked. The inventory can be in any form (electronic or paper), using any or multiple software programs, or using a variety of modules or applications that together as a whole tracks the deposits and deductions. Desirably, the total amount of recycle content withdrawn (or applied to the Recycle PIA) does not exceed the total amount of recycle content allotments or credits on deposit in the recycle inventory (from any source, not only from gasification of recycle textiles). However, if a deficit of recycle content value is realized, the recycle content inventory is

rebalanced to achieve a zero or positive recycle content value available. The timing for rebalancing can be either determined and managed in accordance with the rules of a particular system of accreditation adopted by the size reduced textile derived syngas manufacturer or by one among its Family of Entities, or alternatively, is rebalanced within one (1 ) year, or within six (6) months, or within three (3) months, or within one (1 ) month of realizing the deficit. The timing for depositing an allotment into the recycle inventory, applying an allotment (or credit) to a composition to make a Recycle PIA, and gasifying a recycle textile, need not be simultaneous or in any particular order. In one embodiment, the step of gasifying a particular volume of recycle textiles occurs after the recycle content value or allotment from that volume of recycle textile is deposited into a recycle inventory. Further, the allotments or recycle content values withdrawn from the recycle inventory need not be traceable to recycle textiles or gasifying recycle textiles, but rather can be obtained from any waste recycle stream, and from any method of processing the recycle waste stream. Desirably, at least a portion of the recycle content value in the recycle inventory is obtained from recycle textiles, and optionally at least a portion of recycle textiles are processed in the one or more gasification processes as described herein, optionally within a year of each other and optionally at least a portion of the volume of recycle textiles from which a recycle content value is deposited into the recycle inventory is also processed by any or more of the gasification processes described herein..

[0144] The determination of whether a Recycle PIA is derived directly or indirectly from recycled waste is not on the basis of whether intermediate steps or entities do or do not exist in the supply chain, but rather whether at least a portion of the recycle textile molecules fed to the gasifier can be traced into a Recycle PIA. The Recycle PIA is considered to be directly derived from recycle textile or have direct contact with size reduced textile if at least a portion of the molecules in the Recycle PIA can be traced back, optionally through one or more intermediate steps or entities, to at least a portion of the size reduced textile derived syngas molecules. Any number of intermediaries and intermediate derivates can be made before the Recycle PIA is made.

[0145] A Recycle PIA can be indirectly derived from recycled textiles if no portion of its molecules are obtained from size reduced textile derived syngas molecules or some portion of is molecules are obtained from size reduced textile derived syngas molecules but the Recycle PIA has a recycle content value that exceeds the recycle content value associated with the size reduced textile derived syngas molecules, and in this latter case, a Recycle PIA can be both directly and indirectly derived from recycle textile. [0146] In one embodiment or in combination with any of the mentioned embodiments, the Recycle PIA is indirectly derived from recycle textile or size reduced textile derived syngas. In another embodiment, the Recycle PIA is directly derived from recycle textile or size reduced textile derived syngas. In another embodiment, the Recycle PIA is indirectly derived from recycle textile or size reduced textile derived syngas and no portion of the Recycle PIA is directly derived from the recycle textile or size reduced textile derived syngas.

[0147] In another embodiment, there is provided a variety of methods for apportioning the recycle content among the various Recycle PIA compositions made by any one entity or a combination of entities among the Family of Entities of which the size reduced textile derived syngas manufacturer is a part. For example, the size reduced textile derived syngas manufacturer, of any combination or the entirety of its Family of Entities, or a Site, can:

a. adopt a symmetric distribution of recycle content values among its product(s) based on the same fractional percentage of recycle content in one or more feedstocks, or based on the amount of allotment received. For example, if 5 wt.% of the gasification feedstock is size reduced textiles, or if the recycle content value is 5 wt.% of the entire gasifier feedstock, then all Recycle PIA compositions may contain 5 wt.% recycle content value. In this case, the amount of recycle content in the products is proportional to the amount of recycle content in the feedstock to make the products; or

b. adopt an asymmetric distribution of recycle content values among its product(s) based on the same fractional percentage of recycle content in the one or more feedstocks, or based on the amount of allotment received. For example, if 5 wt.% of the gasifier feedstock is recycle textile, or if the allotment value is 5 wt.% of the entire gasifier feedstock, then one volume or batch of Recycle PIA can receive a greater amount of recycle content value that other batches or volume of Recycle PIA. One batch of PVA can contain 20% recycle content by mass, and another batch can contain zero 0% recycle content, even though both volumes may be compositionally the same, provided that the amount of recycle content value withdrawn from a recycle inventory and applied to the Recycle PIA does not exceed the amount of recycle content value deposited into the recycle inventory, or if a deficit is realized, the overdraft is rebalanced to zero or a positive credit available status as described above. In the asymmetric distribution of recycle content, a manufacturer can tailor the recycle content to volumes of Recycle PIA sold as needed among customers, thereby providing flexibility among customers some of whom may need more recycle content than others in a PVA volume.

[0148] Both the symmetric distribution and the asymmetric distribution of recycle content can be proportional on a Site wide basis, or on a multi-Site basis. In one embodiment or in combination with any of the mentioned embodiments, the recycle content input (recycle textiles or allotments) can be within a Site, and recycle content values from said inputs are applied to one or more compositions made at the same Site to make Recycle PIA. The recycle content values can be applied symmetrically or asymmetrically to one or more different compositions made at the Site.

[0149] In one embodiment or in combination with any of the mentioned embodiments, the recycle content input or creation (recycle content feedstock or allotments) can be to or at a first Site, and recycle content values from said inputs are transferred to a second Site and applied to one or more

compositions made at a second Site. The recycle content values can be applied symmetrically or asymmetrically to the compositions at the second Site.

[0150] In an embodiment, the Recycle PIA has associated with it, or contains, or is labelled, advertised, or certified as containing recycle content in an amount of at least 0.01 wt.%, or at least 0.05 wt.%, or at least 0.1 wt.%, or at least 0.5 wt.%, or at least 0.75 wt.%, or at least 1 wt.%, or at least 1.25 wt.%, or at least 1.5 wt.%, or at least 1.75 wt.%, or at least 2 wt.%, or at least 2.25 wt.%, or at least 2.5 wt.%, or at least 2.75 wt.%, or at least 3 wt.%, or at least 3.5 wt.%, or at least 4 wt.%, or at least 4.5 wt.%, or at least 5 wt.%, or at least 6 wt.%, or at least 7 wt.%, or at least 10 wt.%, or at least 15 wt.%, or at least 20 wt.%, or at least 25 wt.%, or at least 30 wt.%, or at least 35 wt.%, or at least 40 wt.%, or at least 45 wt.%, or at least 50 wt.%, or at least 55 wt.%, or at least 60 wt.%, or at least 65 wt.% and/or the amount can be up to 100 wt.%, or up to 95 wt.%, or up to 90 wt.%, or up to 80 wt.%, or up to 70 wt.%, or up to 60 wt.%, or up to 50 wt.%, or up to 40 wt.%, or up to 30 wt.%, or up to 25 wt.%, or up to 22 wt.%, or up to 20 wt.%, or up to 18 wt.%, or up to 16 wt.%, or up to 15 wt.%, or up to 14 wt.%, or up to 13 wt.%, or up to 1 1 wt.%, or up to 10 wt.%, or up to 8 wt.%, or up to 6 wt.%, or up to 5 wt.%, or up to 4 wt.%, or up to 3 wt.%, or up to 2 wt.%, or up to 1 wt.%, or up to 0.9 wt.%, or up to 0.8 wt.%, or up to 0.7 wt.%. The recycle content associated with the Recycle PIA can be associated by applying an allotment (credit or allocation) to any polymer and/or article made or sold. The allotment can be contained in an inventory of allotments created, maintained or operated by or for the Recycle PIA manufacturer. The allotment can be obtained from any source along any manufacturing chain of products provided that its origin is in gasifying a feedstock containing a fossil fuel and size reduced textiles.

[0151] The amount of recycle content in a reactant compound or composition, or the amount of recycle content applied to the Recycle PIA, needed to feed the gasifier to claim a desired amount of recycle content in the Recycle PIA in the event that all the recycle content from the recycle textile feedstock is applied to the Recycle PIA, can be determined or calculated by any of the following methods:

(i) the amount of an allotment associated with the Recycle PIA used to feed the reactor is determined by the amount certified or declared by the supplier of transferred Recycle PIA, or

(ii) the amount of allocation declared by the entity using Recycle PIA, or

(iii) using a mass balance approach to back-calculate the minimum amount of recycle content in the feedstock from an amount of recycle content declared, advertised, or accounted for by the manufacturer, whether or not accurate, as applied to the Recycle PIA product,

(iv) blending of non-recycle content with recycle content feedstock or associating recycle content to a portion of the feedstock, using pro-rata mass approach

[0152] In one embodiment, the Recycle PIA manufacturer can make Recycle PIA, or process a reactant compound or composition and make a Recycle PIA, or make Recycle PIA by obtaining any source of a reactant compound or composition from a supplier, whether or not such reactant compound or composition has any recycle content, and either:

i. from the same supplier of the reactant compound or composition, also obtain a recycle content allotment applied to either syngas or to any product, article, polymer, or composition, or

ii. from any person or entity, obtaining a recycle content allotment without a supply of a reactant compound or composition from said person or entity transferring said recycle content allotment.

[0153] The allotment in (i) is obtained from a reactant compound or composition supplier, and the reactant compound or composition supplier also supplies reactant compound or composition to the Recycle PIA manufacturer or within its Family of Entities. The circumstance described in (i) allows a Recycle PIA manufacturer to obtain a supply of a reactant compound or composition that is a non-recycle content reactant compound or composition, yet obtain a recycle content allotment from the reactant compound or composition supplier. In one embodiment, the reactant compound or composition supplier transfers a recycle content allotment to the Recycle PIA manufacturer and a supply of reactant compound or composition to the Recycle PIA manufacturer, where the recycle content allotment is not associated with the reactant compound or composition supplied, or even not associated with any reactant compound or composition made by the reactant compound or composition supplier. The recycle content allotment does not have to be tied to an amount of recycle content in a reactant compound or composition or to any monomer used to make Recycle PIA, but rather the recycle content allotment transferred by the reactant compound or composition supplier can be associated with other products having their origin in a size reduced textile derived syngas stream other than those in a reaction scheme to make polymer and/or articles. This allows flexibility among the reactant compound or composition supplier and Recycle PIA manufacturer to apportion a recycle content among the variety of products they each make. In each of these cases, however, the recycle content allotment is associated with gasifying recycle textiles.

[0154] In one embodiment, the reactant compound or composition supplier transfers a recycle content allotment to the Recycle PIA manufacturer and a supply of reactant compound or composition to the Recycle PIA manufacturer, where the recycle content allotment is associated with reactant compound or composition. Optionally, the reactant compound or composition being supplied can be derived from recycle textile feedstock and at least a portion of the recycle content allotment being transferred can be the recycle content in the recycled textile. The recycle content allotment transferred to the Recycle PIA manufacturer can be up front with the reactant compound or composition supplied, optionally in installments, or with each reactant compound or composition installment, or apportioned as desired among the parties.

[0155] The allotment in (ii) is obtained by the Recycle PIA manufacturer (or its Family of Entities) from any person or entity without obtaining a supply of reactant compound or composition from the person or entity. The person or entity can be a reactant compound or composition manufacturer that does not supply reactant compound or composition to the Recycle PIA manufacturer or its Family of Entities, or the person or entity can be a manufacturer that does not make reactant compound or composition. In either case, the

circumstances of (ii) allows a Recycle PIA manufacturer to obtain a recycle content allotment without having to purchase any reactant compound or composition from the entity supplying the recycle content allotment. For example, the person or entity may transfer a recycle content allotment through a buy/sell model or contract to the Recycle PIA manufacturer or its Family of Entities without requiring purchase or sale of an allotment (e.g. as a product swap of products that are not a reactant compound or composition), or the person or entity may outright sell the allotment to the Recycle PIA

manufacturer or one among its Family of Entities. Alternatively, the person or entity may transfer a product, other than a reactant compound or composition, along with its associated recycle content allotment to the Recycle PIA manufacturer. This can be attractive to a Recycle PIA manufacturer that has a diversified business making a variety of products other than Recycle PIA requiring raw materials other than a reactant compound or composition that the person or entity can supply to the Recycle PIA manufacturer.

[0156] The allotment can be deposited into a recycle inventory (e.g. an inventory of allotments). In one embodiment, the allotment is an allocation created by the manufacturer of the size reduced textile derived syngas stream. The Recycle PIA manufacturer cam also make a polymer and/or article, whether or not a recycle content is applied to the polymer and/or article and whether or not recycle content, if applied to the polymer and/or article, is drawn from the inventory. For example, either the size reduced textile derived syngas stream manufacturer and/or the Recycle PIA

manufacturer may:

a. deposit the allotment into an inventory and merely store it; or b. deposit the allotment into an inventory and apply allotments from the inventory to products other than;

i. any products derived directly or indirectly from the size reduced textile derived syngas stream, or

ii. to a polymer and/or articles made by the Recycle PIA manufacturer, or c. sell or transfer an allocation from the inventory into which at least one allotment, obtained as noted above, was deposited.

[0157] If desired, however, from that inventory, any recycle content allotment can be deducted in any amount and applied to a polymer and/or article to make a Recycle PIA. For example, a Recycle inventory of allotments can be generated having a variety of sources for creating the allotments. Some recycle content allotments (credits) can have their origin in methanolysis of recycle waste, or from gasification of other types of recycle waste, or from mechanical recycling of waste plastic or metal recycling, and/or from pyrolyzing recycle waste, or from any other chemical or mechanical recycling technology. The recycle inventory may or may not track the origin or basis of obtaining a recycle content value, or the inventory may not allow one to associate the origin or basis of an allocation to the allocation applied to Recycle PIA. It is sufficient that an allocation is deducted from an allocation inventory and applied to Recycle PIA regardless of the source or origin of the allocation, provided that a recycle content allotment derived from a recycle textile feedstock containing a fossil fuel and size reduced textiles is present in the allotment inventory as the time of withdrawal, or a recycle content allotment is obtained by the Recycle PIA manufacturer as specified in step (i) or step (ii), whether or not that recycle content allotment is actually deposited into the inventory. In one embodiment, the recycle content allotment obtained in step (i) or (ii) is deposited into an inventory of allotments. In one

embodiment, the recycle content allotment deducted from the inventory and applied to the Recycle PIA originates from recycle textiles or size reduced textiles, whereby the size reduced textiles are ultimately gasified with a fossil fuel.

[0158] As used throughout, the inventory of allotments can be owned by the size reduced textile derived syngas manufacturer, or by the Recycle PIA manufacturer, or operated by either of them, or owned or operated by neither but at least in part for the benefit of either of them, or licensed by either of them. Also, as used throughout, the size reduced textile derived syngas manufacturer or the Recycle PIA manufacturer may also include either of their Family of Entities. For example, while either of them may not own or operate the inventory, one among its Family of Entities may own such a platform, or license it from an independent vendor, or operate it for either of them.

Alternatively, an independent entity may own and/or operate the inventory and for a service fee operate and/or manage at least a portion of the inventory for either of them.

[0159] In one embodiment, the Recycle PIA manufacturer obtains a supply of reactant compound or composition from a supplier, and also obtains an allotment from the supplier, where such allotment is derived from gasifying a feedstock containing a fossil fuel and size reduced textiles, and optionally the allotment is associated with the reactant compound or composition supplied by the supplier. In one embodiment, at least a portion of the allotment obtained by the Recycle PIA manufacturer is either:

a. applied to Recycle PIA made by the supply of reactant compound or composition;

b. applied to Recycle PIA not made by the supply of reactant compound or composition, such as would be the case where Recycle PIA is already made and stored in inventory or future made Recycle PIA; or

c. deposited into an inventory from which is deducted an allocation applied to Recycle PIA (the Recycle PIA applied allocation) and the deposited allocation either does, or does not, contribute to the amount of allocations from which the Recycle PIA applied allocation is drawn.

d. deposited into an inventory and stored.

[0160] It is not necessary in all embodiments that recycle textile feedstock is used to make Recycle PIA composition or that the Recycle PIA was obtained from a recycle content allotment associated with a reactant compound or composition. Further, it is not necessary that an allotment be applied to the feedstock for making the Recycle PIA to which recycle content is applied. Rather, as noted above, the allotment, even if associated with a reactant compound or composition when the reactant compound or composition is obtained, can be deposited into an electronic inventory. In one embodiment, however, recycle textile feedstock associated with the allotment is used to make the Recycle PIA composition. In one embodiment, the Recycle PIA is obtained from a recycle content allotment associated with a recycle textile feedstock, or with size reduced textiles, or with gasifying size reduced textiles. In one embodiment, at least a portion of the allotments obtained from recycle textile made into size reduced textiles, or the size reduced textiles, or gasifying sized reduced textiles are applied to Recycle PIA to make a Recycle PIA.

[0161] In one embodiment, the size reduced textile derived syngas stream manufacturer generates an allotment by gasifying a combination of a fossil fuel and sized reduced textiles, and either:

a. Applies the allotment to any compound or composition

(whether liquid or solid or polymer in any form, including pellets, sheet, fibers, flake, etc.) made directly or indirectly (e.g. through a reaction scheme of several intermediates) from the size reduced textile derived syngas stream; or

b. Applies the allotment to a compound or composition not made directly or indirectly from the size reduced textile derived syngas stream, such as would be the case where reactant compounds or compositions are already made and stored in inventory or future made non-recycle content reactant compounds or compositions; or

c. deposited into an inventory from which is deducted any

allocation that is applied to reactant compounds or

compositions; and the deposited allocation either is or is not associated with the particular allocation applied to the reactant compounds or compositions; or d. is deposited into an inventory and stored for use at a later time.

[0162] In any of the embodiments described throughout, the timing for taking the allotment, or depositing the allotment into a recycle inventory, can be as early as when a recycle textile is received or owned by a Recipient or one among its Family of Entities, or when it is converted to sized reduced textiles, or when a Recipient or one among its Family of Entities receives or owns sized reduced textiles, or when they are combined with a fossil fuel, or when gasified, or when a size reduced textile derived syngas is made. For clarification, an allotment is deemed generated or obtained by or originating from gasifying sized reduced textiles even though the timing of taking or recognizing the allotment is earlier or later than the actual time the sized reduced textiles are gasified, provided that the sized reduced textiles are subjected to gasification.

[0163] There is now also be provided a package or a combination of a Recycle PIA and a recycle content identifier associated with Recycle PIA, where the identifier is or contains a representation that the Recycle PIA contains, or is sourced from or associated with a recycle content. The package can be any suitable package for containing a polymer and/or article, such as a plastic or metal drum, railroad car, isotainer, totes, polytote, bale, IBC totes, bottles, compressed bales, jerricans, and polybags, spools, roving, winding, or cardboard packaging. The identifier can be a certificate document, a product specification stating the recycle content, a label, a logo or certification mark from a certification agency representing that the article or package contains contents or the Recycle PIA contains, or is made from sources or associated with recycle content, or it can be electronic statements by the Recycle PIA manufacturer that accompany a purchase order or the product, or posted on a website as a statement, representation, or a logo representing that the Recycle PIA contains or is made from sources that are associated with or contain recycle content, or it can be an advertisement transmitted electronically, by or in a website, by email, or by television, or through a tradeshow, in each case that is associated with Recycle PIA. The identifier need not state or represent that the recycle content is derived from gasifying a feedstock containing a fossil fuel and size reduced textiles. Rather, the identifier can merely convey or communicate that the Recycle PIA has or is sourced from a recycle content, regardless of the source. However, the Recycle PIA has a recycle content allotment that, at least in part, associated with gasifying sized reduced textiles.

[0164] In one embodiment, one may communicate recycle content information about the Recycle PIA to a third party where such recycle content information is based on or derived from at least a portion of the allocation or credit. The third party may be a customer of the size reduced textile derived syngas manufacturer or Recycle PIA manufacturer or supplier, or may be any other person or entity or governmental organization other than the entity owning either of them. The communication may electronic, by document, by advertisement, or any other means of communication.

[0165] In one embodiment, there is provided a system or package comprising:

a. Recycle PIA or article made thereby, and

b. an identifier such as a credit, label or certification associated with said Recycle PIA or article made thereby, where the identifier is a representation that the polymer and/or article or article made thereby has, or is sourced from, a recycle content provided that the Recycle PIA or article made thereby has an allotment, or is made from a reactant compound or composition, at least in part associated with gasifying fossil fuels and sized reduced textiles.

[0166] The system can be a physical combination, such as package having at least Recycle PIA as its contents and the package has a label, such as a logo, that the contents such as the Recycle PIA has or is sourced from a recycle content. Alternatively, the label or certification can be issued to a third party or customer as part of a standard operating procedure of an entity whenever it transfers or sells Recycle PIA having or sourced from recycle content. The identifier does not have to be physically on the Recycle PIA or on a package, and does not have to be on any physical document that accompanies or is associated with the Recycle PIA. For example, the identifier can be an electronic credit transferred electronically by the Recycle PIA manufacturer to a customer in connection with the sale or transfer of the Recycle PIA product, and by sole virtue of being a credit, it is a representation that the Recycle PIA has recycle content. The identifier itself need only convey or communicate that the Recycle PIA has or is sourced from a recycle content, regardless of the source. In one embodiment, articles made from the Recycle PIA may have the identifier, such as a stamp or logo embedded or adhered to the article. In one embodiment, the identifier is an electronic recycle content credit from any source. In one embodiment, the identifier is an electronic recycle content credit having its origin in gasifying a feedstock containing a fossil fuel and size reduced textiles.

[0167] The Recycle PIA is made from a reactant compound or

composition, whether or not the reactant is a recycle content reactant (r- reactant). Once a Recycle PIA composition is made, it can be designated as having recycle content based on and derived from at least a portion of the allotment, again whether or not the recycle textile feedstock is used to make the Recycle PIA composition. The allocation can be withdrawn or deducted from inventory. The amount of the deduction and/or applied to the Recycle PIA can correspond to any of the methods described above, e.g. a mass balance approach.

[0168] In an embodiment, a Recycle PIA composition can be made by having an inventory of allocations, and reacting a reactant compound or composition a synthetic process to make a Recycle PIA, and applying a recycle content to that Recycle PIA to thereby obtain a Recycle PIA by deducting an amount of allocation from an inventory of allocations. A Recycle PIA manufacturer may have an inventory of allocations by itself or one among its Family of Entities owning, possessing, or operating the inventory, or a third party operating at least a portion of the inventory for the Recycle PIA manufacturer or its Family of Entities or as a service provided to the Recycle PIA manufacturer or one among its Family of Entities. The amount of allocation deducted from inventory is flexible and will depend on the amount of recycle content applied to the Recycle PIA. It should be at least sufficient to correspond with at least a portion if not the entire amount of recycle content applied to the Recycle PIA. The method of calculation can be a mass balance approach or the methods of calculation described above. The inventory of allocations can be established on any basis and may be a mix of basis, provided that at least some amount of allocation in the inventory is attributable to gasifying a feedstock containing a fossil fuel and size reduced textiles. The recycle content allotment applied to the Recycle PIA does not have to have its origin in gasifying a feedstock containing a fossil fuel and size reduced textiles, and instead can have its origin in any other method of generating allocations from recycle waste, such as through methanolysis or gasification of recycle waste, provided that the inventory of allotments also contains an allotment or has an allotment deposit having its origin in gasifying a feedstock containing a fossil fuel and size reduced textiles.. In one embodiment, however, the recycle content applied to the Recycle PIA is an allotment obtained from gasifying a feedstock containing at least size reduced textiles.

[0169] The following are examples of designating or declaring a recycle content to Recycle PIA or a recycle content to a reactant compound or composition:

1. A Recycle PIA manufacturer applies at least a portion of an allotment to a polymer and/or article composition where the allotment is associated with size reduced textile derived syngas stream, and the reactant compound or composition used to make the Recycle PIA did not contain any recycle content or it did contain recycle content; or

2. A Recycle PIA manufacturer applies at least a portion of an allotment to a polymer and/or article composition where the allotment is derived directly or indirectly with a recycle content reactant compound or composition, whether or not such reactant compound or composition volume is used to make the Recycle PIA; or

3. A Recycle PIA manufacturer applies at least a portion of an allotment to a Recycle PIA composition where the allotment is derived directly or indirectly from a recycle textile feedstock used to make the Recycle PIA to which the allotment is applied, and:

a. all of the recycle content in the recycle textile feedstock is applied to determine the amount of recycle content in the Recycle PIA, or

b. only a portion of the recycle content in the recycle textile feedstock is applied to determine the amount of recycle content applied to the Recycle PIA, the remainder stored in inventory for use to future Recycle PIA, or for application to other existing Recycle PIA made from recycle textile feedstock not containing any recycle content, or to increase the recycle content on an existing Recycle PIA, or a combination thereof, or

c. none of the recycle content in the recycle content feedstock is applied to the Recycle PIA and instead is stored in an inventory, and a recycle content from any source or origin is deducted from the inventory and applied to Recycle PIA; or

4. A Recycle PIA manufacturer applies at least a portion of an allotment to a reactant compound or composition used to make a Recycle PIA to thereby obtain a Recycle PIA, where the allotment was obtained with the transfer or purchase of the same reactant compound or composition used to make the Recycle PIA and the allotment is associated with the recycle content in a reactant compound or composition; or

5. A Recycle PIA manufacturer applies at least a portion of an allotment to a reactant compound or composition used to make a Recycle PIA to thereby obtain a Recycle PIA, where the allotment was obtained with the transfer or purchase of the same reactant compound or composition used to make the Recycle PIA and the allotment is not associated with the recycle content in a reactant compound or composition but rather on the recycle content of a monomer used to make the reactant compound or composition; or

6. A Recycle PIA manufacturer applies at least a portion of an allotment to a reactant compound or composition used to make a Recycle PIA to thereby obtain a Recycle PIA, where the allotment was not obtained with the transfer or purchase of the reactant compound or composition and the allotment is associated with the recycle content in the reactant compound or composition; or

7. A Recycle PIA manufacturer applies at least a portion of an allotment to a reactant compound or composition used to make a Recycle PIA to thereby obtain a Recycle PIA, where the allotment was not obtained with the transfer or purchase of the reactant compound or composition and the allotment is not associated with the recycle content in the reactant compound or composition but rather with the recycle content of any monomers used to make the reactant compound or composition; or

8. A Recycle PIA manufacturer obtains an allotment having it origin in gasifying a feedstock containing a fossil fuel and size reduced textiles., and:

a. no portion of the allotment is applied to a reactant compound or composition to make Recycle PIA and at least a portion is applied to Recycle PIA to make a Recycle PIA; or

b. less than the entire portion is applied to a reactant compound or composition used to make Recycle PIA and the remainder is stored in inventory or is applied to future made Recycle PIA or is applied to existing Recycle PIA in inventory. [0170] In one embodiment, the Recycle PIA, or articles made thereby, can be offered for sale or sold as Recycle PIA containing or obtained with recycle content. The sale or offer for sale can be accompanied with a certification or representation of the recycle content claim made in association with the Recycle PIA or article made with the Recycle PIA.

[0171] The obtaining of an allocation and designating (whether internally such as through a bookkeeping or an inventory tracking software program or externally by way of declaration, certification, advertising, representing, etc.) can be by the Recycle PIA manufacturer or within the Recycle PIA

manufacturer Family of Entities. The designation of at least a portion of the Recycle PIA as corresponding to at least a portion of the allotment (e.g.

allocation or credit) can occur through a variety of means and according to the system employed by the Recycle PIA manufacturer, which can vary from manufacturer to manufacturer. For example, the designation can occur internally merely through a log entry in the books or files of the Recycle PIA manufacturer or other inventory software program, or through an

advertisement or statement on a specification, on a package, on the product, by way of a logo associated with the product, by way of a certification declaration sheet associated with a product sold, or through formulas that compute the amount deducted from inventory relative to the amount of recycle content applied to a product.

[0172] Optionally, the Recycle PIA can be sold. In one embodiment, there is provided a method of offering to sell or selling polymer and/or articles by:

a. A Recycle PIA manufacturer or its Family of Entities obtaining or generating a recycle content allocation, and the allocation can be obtained by any of the means described herein and can be deposited into inventory, the recycle content allocation having its origin in gasification of a feedstock containing a fossil fuel and size reduced textiles,

b. converting a reactant compound or composition in a synthetic process to make a compound, composition, polymer and/or article composition, and the reactant compound or composition can be any reactant compound or composition or a reactant compound or composition,

c. designating (e.g. assigning or associating) a recycle content to at least a portion of the compound, composition, polymer and/or article composition from an inventory of allocations, where the inventory contains at least one entry that is an allocation associated with gasification of a feedstock containing a size reduced textile. The designation can be the amount of allocation deducted from inventory, or the amount of recycle content declared or determined by the Recycle PIA manufacturer in its accounts. Thus, the amount of recycle content does not necessarily have to be applied to the Recycle PIA product in a physical fashion. The designation can be an internal designation to or by the Recycle PIA manufacturer or its Family of Entities or a service provider in contractual relationship to the Recycle PIA manufacturer or its Family of Entities, and d. offering to sell or selling the compound, composition, polymer and/or article composition as containing or obtained with recycle content corresponding at least in part with such designation.

The amount of recycle content represented as contained in the Recycle PIA sold or offered for sale has a relationship or linkage to the designation. The amount of recycle content can be a 1 :1 relationship in the amount of recycle content declared on a Recycle PIA offered for sale or sold and the amount of recycle content assigned or designated to the Recycle PIA by the Recycle PIA manufacturer.

[0173] The steps described need not be sequential, and can be

independent from each other. For example, the step a) of obtaining an allocation and the step of making Recycle PIA from a reactant compound or composition can be simultaneous. [0174] As used throughout, the step of deducting an allocation from an inventory of allocations does not require its application to a Recycle PIA product. The deduction also does not mean that the quantity disappears or is removed from the inventory logs. A deduction can be an adjustment of an entry, a withdrawal, an addition of an entry as a debit, or any other algorithm that adjusts inputs and outputs based on an amount recycle content associated with a product and one or a cumulative amount of allocations on deposit in the inventory. For example, a deduction can be a simple step of a reducing/debit entry from one column and an addition/credit to another column within the same program or books, or an algorithm that automates the deductions and entries/additions and/or applications or designations to a product slate. The step of applying an allocation to a Recycle PIA product where such allocation was deducted from inventory also does not require the allocation to be applied physically to a Recycle PIA product or to any document issued in association with the Recycle PIA product sold. For example, a Recycle PIA manufacturer may ship Recycle PIA product to a customer and satisfy the“application” of the allocation to the Recycle PIA product by electronically transferring a recycle content credit to the customer.

[0175] In one embodiment, the amount of recycle content in the recycle textile feedstock or in the Recycle PIA will be based on the allocation or credit obtained by the manufacturer of the Recycle PIA composition or the amount available in the Recycle PIA manufacturer’s inventory of allotments. A portion or all of the allocation or credit obtained by or in the possession of a manufacturer of Recycle PIA can be designated and assigned to a recycle textile feedstock or Recycle PIA on a mass balance basis. The assigned value of the recycle content to the recycle textile feedstock or Recycle PIA should not exceed the total amount of all allocations and/or credits available to the manufacturer of the Recycle PIA or other entity authorized to assign a recycle content value to the Recycle PIA.

[0176] There is now also provided a method of introducing or establishing a recycle content in a compound, composition, polymer and/or article without necessarily using an reactant compound or composition feedstock. In this method,

a. a syngas manufacturer makes a size reduced textile derived syngas stream and

b. a polymer and/or article manufacturer:

i. obtains an allotment associated with gasifying size reduced textiles,

ii. makes a polymer and/or article from any reactant compound or composition, and

iii. associates at least a portion of the allotment with at least a portion of the polymer and/or article, whether or not the reactant compound or composition used to make the polymer and/or article contains a recycle content.

[0177] In this method, the polymer and/or article manufacturer need not purchase recycle reactant compound or composition from a particular source or supplier, and does not require the polymer and/or article manufacturer to use or purchase a reactant compound or composition having recycle content in order to successfully establish a recycle content in the polymer and/or article composition. The reactant compound or composition manufacturer may use any source of reactant compound or composition and apply at least a portion of the allocation or credit to at least a portion of the reactant compound or composition feedstock or to at least a portion of the polymer and/or article product. The association by the polymer and/or article manufacturer may come in any form, whether by on in its inventory, internal accounting methods, or declarations or claims made to a third party or the public.

[0178] There is also provided a use for size reduced textiles, the use including converting size reduced textiles in any synthetic process, such as gasification, to make size reduced textile derived syngas and/or Recycle PIA.

[0179] There is also provided a use for a reactant compound or composition that includes converting a reactant compound or composition in a synthetic process to make polymer and/or articles and applying at least a portion of an allotment to the polymer and/or article to the reactant compound or composition, where the allotment has its origin in gasifying a feedstock containing a fossil fuel and size reduced textiles or has its origin in an inventory of allotments where at least one deposit made into the inventory has its origin in gasifying a feedstock containing a fossil fuel and size reduced textiles.

[0180] In one embodiment, there is provided a polymer and/or article composition that is obtained by any of the methods described above.

[0181] The reactant compound or composition, such as a reactant compound or composition can be stored in a storage vessel and transferred to a Recycle PIA manufacturing facility by way of truck, pipe, or ship, or as further described below, the reactant compound or composition production facility can be integrated with the Recycle PIA facility. The reactant compound or composition may be shipped or transferred to the operator or facility that makes the polymer and/or article.

[0182] In an embodiment, the process for making Recycle PIA can be an integrated process. One such example is a process to make Recycle PIA by:

a. gasifying a feedstock containing a fossil fuel and size reduced textiles to make a size reduced textile derived syngas stream;

b. reacting said syngas or a non-recycle content syngas made in the gasifier in a reaction scheme to make a reactant compound or composition;

c. reacting any reactant compound or composition in a synthetic process to make a polymer and/or article;

d. depositing an allotment into an inventory of allotments, said allotment originating from gasifying a feedstock containing a fossil fuel and size reduced textiles.; and e. applying any allotment from said inventory to the polymer and/or article to thereby obtain a recycle content polymer and/or article composition.

[0183] In one embodiment, one may integrate two or more facilities and make Recycle PIA. The facilities to make Recycle PIA, the reactant compound or composition, or the syngas can be stand-alone facilities or facilities integrated to each other. For example, one may establish a system of producing and consuming a reactant compound or composition, as follows:

a. provide a reactant compound or composition manufacturing

facility configured to produce a reactant compound or composition;

b. provide a polymer and/or article manufacturing facility having a reactor configured to accept a reactant compound or composition from the reactant compound or composition manufacturing facility; and

a supply system providing fluid communication between these two facilities and capable of supplying a reactant compound or composition from the reactant compound or composition manufacturing facility to the polymer and/or article manufacturing facility, wherein the reactant compound or composition manufacturing facility generates or participates in a process to generate allotments and gasifies a feedstock containing fossil fuel and recycle sized reduced textiles, and:

(i) said allotments are applied to the reactant compounds or

compositions or to the polymer and/or article reactant, or

(ii) are deposited into an inventory of allotments, and any allotment is withdrawn from the inventory an applied to the reactant

compositions or to the polymer and/or article.

[0184] The Recycle PIA manufacturing facility can make Recycle PIA by accepting any reactant compound or composition from the reactant compound or composition manufacturing facility and applying a recycle content to

Recycle PIA made with the reactant compound or composition by deducting allotments from its inventory and applying them to the Recycle PIA, optionally in amounts using the methods described above. The allotments obtained and stored in inventory can be obtained by any of the methods described above. The allotments withdrawn from inventory and applied can be allotments obtained by any source of recycle content and need not necessarily be allotments associated with gasifying size reduced textiles.

[0185] In one embodiment, there is also provided a system for producing Recycle PIA as follows:

a. provide a gasification manufacturing facility configured to produce an output composition comprising a size reduced textile derived syngas stream;

b. provide a reactant compound or composition manufacturing facility configured to accept a size reduced textile derived syngas stream from the gasification manufacturing facility and making, through a reaction scheme one or more downstream products of said syngas to make an output composition comprising a reactant compound or composition; c. provide a polymer and/or article (Recycle PIA) manufacturing facility having a reactor configured to accept a reactant compound or composition and making an output composition comprising a recycle content Recycle PIA; and

d. a supply system providing fluid communication between at least two of these facilities and capable of supplying the output composition of one manufacturing facility to another one or more of said manufacturing facilities.

[0186] The Recycle PIA manufacturing facility can make Recycle PIA. In this system, the gasification manufacturing facility can have its output in fluid communication with the reactant compound or composition manufacturing facility which in turn can have its output in fluid communication with the Recycle PIA manufacturing facility. Alternatively, the manufacturing facilities of a) and b) alone can be in fluid communication, or only b) and c). In the latter case, the Recycle PIA manufacturing facility can make Recycle PIA directly by having the size reduced textile derived syngas produced in the gasification manufacturing facility converted all the way to Recycle PIA, or indirectly by accepting any reactant compound or composition from the reactant compound or composition manufacturing facility and applying a recycle content to Recycle PIA by deducting allotments from its inventory and applying them to the Recycle PIA, optionally in amounts using the methods described above. The allotments obtained and stored in inventory can be obtained by any of the methods described above,

[0187] The fluid communication can be gaseous or liquid or both The fluid communication need not be continuous and can be interrupted by storage tanks, valves, or other purification or treatment facilities, so long as the fluid can be transported from the manufacturing facility to the subsequent facility through an interconnecting pipe network and without the use of truck, train, ship, or airplane. Further, the facilities may share the same site, or in other words, one site may contain two or more of the facilities. Additionally, the facilities may also share storage tank sites, or storage tanks for ancillary chemicals, or may also share utilities, steam or other heat sources, etc., yet also be considered as discrete facilities since their unit operations are separate. A facility will typically be bounded by a battery limit.

[0188] In one embodiment, the integrated process includes at least two facilities co-located within 5, or within 3, or within 2, or within 1 mile of each other (measured as a straight line). In one embodiment, at least two facilities are owned by the same Family of Entities.

[0189] In an embodiment, there is also provided an integrated Recycle PIA generating and consumption system. This system includes:

a. a gasification manufacturing facility configured to produce an output composition comprising a size reduced textile derived syngas stream obtained by gasifying fossil fuel and recycle sized reduced textiles; b. a reactant compound or composition manufacturing facility configured to accept a size reduced textile derived syngas stream from the gasification manufacturing facility and making, through a reaction scheme one or more downstream products of said syngas to make an output composition comprising a reactant compound or composition;

c. a polymer and/or article (Recycle PIA) manufacturing facility having a reactor configured to accept a reactant compound or composition and making an output composition comprising a recycle content Recycle PIA; and

d. a piping system interconnecting at least two of said facilities, optionally with intermediate processing equipment or storage facilities, capable of taking off the output composition from one facility and accept said output at any one or more of the other facilities.

[0190] The system does not necessarily require a fluid communication between the two facilities, although fluid communication is desirable. For example, the size reduced textile derived syngas can be delivered to the reactant compound or composition facility through the interconnecting piping network that can be interrupted by other processing equipment, such as treatment, purification, pumps, compression, or equipment adapted to combine streams, or storage facilities, all containing optional metering, valving, or interlock equipment. The equipment can be a fixed to the ground or fixed to structures that are fixed to the ground. The interconnecting piping does not need to connect to the reactant compound or composition reactor or the cracker, but rather to a delivery and receiving point at the respective facilities. The interconnecting pipework need not connect all three facilities to each other, but rather the interconnecting pipework can be between facilities a)-b), or b)-c), or between a)-b)-c).

[0191] Generally, in a synthesis gas operation one or more feedstock composition(s) comprised of (i) fossil fuel sources (e.g. coal, petcoke) or (i) liquid fuel sources, or a combination of solid and liquid fuel sources, and size reduced textiles that are not densified as an individual stream or combined with the solids or liquids fuel source streams, and optionally water and other chemical additives, are fed or injected into a chamber of a synthesis gas generator (gasifier) and gasified in the presence of an oxidizer such as oxygen, also fed to the gasifier. A hot syngas stream is produced in the gasification zone at high temperature generating gases including hydrogen, carbon monoxide, carbon dioxide and can include other gases such as methane, hydrogen sulfide and nitrogen depending on the fuel source and reaction conditions. The cooled product gas stream removed from the gasifier (the raw syngas stream) can be further treated with water to remove remaining solids such as soot, and then further treated to remove acid gas (e.g. hydrogen sulfide) after optionally further cooling and shifting the ratio of carbon monoxide to hydrogen.

[0192] For purposes of classifying materials in the feedstock composition, a fossil fuel used is coal, petcoke, or any other solid at 25°C and 1

atmosphere that is a byproduct from refining oil or petroleum. The fossil fuel portion of the feedstock composition is to be distinguished from size reduced textiles, even if the size reduced textiles are carbonaceous and in part derived from raw materials obtained from refining crude oil.

[0193] Unless otherwise stated, reference the weight of the feedstock composition includes all solids, and if present liquids, fed to the gasifier, and unless otherwise stated, does not include the weight of any gases in the feedstock composition as fed to the injector or gasifier.

[0194] For purposes of classifying materials in the feedstock composition, a fossil fuel used is coal, petcoke, or any other solid at 25°C and 1

atmosphere that is a byproduct from refining oil or petroleum. The fossil fuel portion of the feedstock composition is to be distinguished from size reduced textiles, even if the size reduced textiles are carbonaceous and in part derived from raw materials obtained from refining crude oil. [0195] The size reduced textiles employed as a feedstock to the gasifier are solid at 25°C at 1 atm. The size reduced textiles are a collection of size reduced textile particles, briquettes, rods, or any other shape or size that different from the native shape of the textile from which the size reduced textile is made.

[0196] Textiles as used herein are natural and/or synthetic fibers, rovings, yarns, nonwoven webs, cloth, fabrics and products made from or containing any of the aforementioned items, provided that the textiles are either post consumer or post-industrial textiles.

[0198] The nonwoven webs that are classified as textiles do not include the category of wet laid nonwoven webs and articles made therefrom. While a variety of articles having the same function can be made from a dry or wet laid process, the article made from the dry laid nonwoven web is classified as a textile. Examples of suitable articles that may be formed from dry laid nonwoven webs as described herein can include those for personal, consumer, industrial, food service, medical, and other types of end uses. Specific examples can include, but are not limited to, baby wipes, flushable wipes, disposable diapers, training pants, feminine hygiene products such as sanitary napkins and tampons, adult incontinence pads, underwear, or briefs, and pet training pads.

Nonwoven webs can also be used as padding for pillows, mattresses, and upholstery, batting for quilts and comforters. In the medical and industrial fields, nonwoven webs of the present invention may be used for medical and industrial face masks, protective clothing, caps, and shoe covers, disposable sheets, surgical gowns, drapes, bandages, and medical dressings.

Additionally, nonwoven webs as described herein may be used for

environmental fabrics such as geotextiles and tarps, oil and chemical absorbent pads, as well as building materials such as acoustic or thermal insulation, tents, lumber and soil covers and sheeting. Nonwoven webs may also be used for other consumer end use applications, such as for, carpet backing, packaging for consumer, industrial, and agricultural goods, thermal or acoustic insulation, and in various types of apparel. The dry laid nonwoven webs as described herein may also be used for a variety of filtration applications, including transportation (e.g., automotive or aeronautical), commercial, residential, industrial, or other specialty applications. Examples can include filter elements for consumer or industrial air or liquid filters (e.g., gasoline, oil, water), including nanofiber webs used for microfiltration, as well as end uses like tea bags, coffee filters, and dryer sheets. Further, nonwoven webs as described herein may be used to form a variety of components for use in automobiles, including, but not limited to, brake pads, trunk liners, carpet tufting, and under padding.

[0199] The textiles can include single type or multiple type of natural fibers and/or single type or multiple type of synthetic fibers. Examples of textile fiber combinations include all natural, all synthetic, two or more type of natural fibers, two or more types of synthetic fibers, one type of natural fiber and one type of synthetic fiber, one type of natural fibers and two or more types of synthetic fibers, two or more types of natural fibers and one type of synthetic fibers, and two or more types of natural fibers and two or more types of synthetic fibers.

[0200] Polymers used to make the synthetic fibers can be thermoplastic or thermosetting polymers. The polymer number average molecular weight can be at least 300, or at least 500, or at least 1000, or at least 5,000, or at least 10,000, or at least 20,000, or at least 30,000, or at least 50,000 or at least 70,000 or at least 90,000 or at least 100,000 or at least 130,000. The weight average molecular weight of the polymers can be at least 300, or at least 500, or at least 1000, or at least 5,000, or at least 10,000, or at least 20,000, or at least 30,000 or at least 50,000, or at least 70,000, or at least 90,000, or at least 100,000, or at least 130,000, or at least 150,000, or at least 300,000.

[0201] Natural fibers include those that are plant derived or animal derived. Natural fibers can be cellulosics, hemicellulosics, and lignins. Examples of plant derived natural fibers include hardwood pulp, softwood pulp, and wood flour; and other plant fibers including those in wheat straw, rice straw, abaca, coir, cotton, flax, hemp, jute, bagasse, kapok, papyrus, ramie, rattan, vine, kenaf, abaca, henequen, sisal, soy, cereal straw, bamboo, reeds, esparto grass, bagasse, Sabai grass, milkweed floss fibers, pineapple leaf fibers, switch grass, lignin-containing plants, and the like. Examples of animal derived fibers include wool, silk, mohair, cashmere, goat hair, horse hair, avian fibers, camel hair, angora wool, and alpaca wool.

[0202] Synthetic fibers are those fibers that are, at least in part,

synthesized or derivatized through chemical reactions, or regenerated, and include, but are not limited to, rayon, viscose, mercerized fibers or other types of regenerated cellulose (conversion of natural cellulose to a soluble cellulosic derivative and subsequent regeneration) such as lyocell (also known as Tencel), Cupro, Modal, acetates such as polyvinylacetate, polyamides including nylon, polyesters such as those polyethylene terephthalate (PET), copolyesters including those made with IPA, CHDM and/or 2, 2,4,4- tetramethyl-1 ,3-cyclobutanediol, polycyclohexylenedimethylene terephthalate (PCT) and other copolymers, olefinic polymers such as polypropylene and polyethylene, polycarbonates, poly sulfates, poly sulfones, polyethers, polyacrylates, acrylonitrile copolymers, polyvinylchloride (PVC), polylactic acid, polyglycolic acid, sulfopolyester fibers, and combinations thereof.

[0203] The size reduced textiles are obtained from post-consumer textiles and/or post-industrial textiles. Post-consumer textiles are those that have been used at least once for its intended application for any duration of time regardless of wear. Post-industrial size reduced textiles include rework, regrind, scrap, trim, out of specification textiles (e.g. fibers, yarns, webs, cloths, fabrics, finished textiles) that have not been used for their intended application, or any textiles that have not been used by the end consumer.

[0204] The form of the textiles useful to make size reduced textiles are not limited, and can include any of the forms of articles or materials used to make textiles described above; e.g. fibers, yarns, fabrics, cloths, finished article forms, or pieces thereof. The size reduced textiles can be of varying age and composition.

[0205] The source of the post-consumer or postindustrial textiles are not limited, and can include textiles present in and separated from municipal solid waste streams (“MSW”). For example, an MSW stream can be processed and sorted to several discrete components, including textiles, fibers, papers, wood, glass, metals, etc. Other sources of textiles include those obtained by collection agencies, or by or for or on behalf of textile brand owners or consortiums or organizations, or from brokers, or from postindustrial sources such as scrap from mills or commercial production facilities, unsold fabrics from wholesalers or dealers, from mechanical and/or chemical sorting or separation facilities, from landfills, or stranded on docks or ships.

[0206] The size reduced textiles do not need to be densified by any agglomeration method or heat treatment method that heats the thermoplastic polymer in the textile to its softening point, or its T_g, or which melts a portion of the textile, to provide a binding matrix that encapsulates or otherwise binds thermosetting polymers and natural fibers in the textiles (“densification”).

Heat can be applied during the size reduction process to dry the textile feed or the size reduced textiles, but such heat is insufficient to heat the size reduced textiles to their softening point. Generally, size reduced textiles are not compacted although compaction is permitted without agglomerating the particles to make larger particles that are self-supporting and retain their shape under when sifted or handled or poured. The size reduced textiles are not densified, or isolated size reduced textiles are not densified, or the sized reduced textiles fed to a gasifier are not densified, or the size reduced textiles are not densified prior to combining them with a fuel fed to a gasifier.

[0207] The size reduced textiles are fed to a fuel for gasification, or to a gasifier neat, or slurried and fed to a gasifier.

[0208] To obtain the size reduced textiles, the textiles are reduced in size by any means, including by chopping, shredding, harrowing, confrication, pulverizing, or cutting a feedstock of textiles to make size reduced textiles. Optionally, the size reduced textiles can continue to be cut, comminuted, pulverized or otherwise size reduced to obtain the desired average particle size if one desires to obtain particles. The form of the size reduced textiles will depend on the desired method of size reduction. For example, the size reduced textiles can be in the form of coarse or fine particles, even a powder (of any shape other than the original shape of the textile feed). Alternatively, the size reduced textiles can be in the form of shredded pieces, long strips, or randomly shaped pieces having a wide variety of shapes.

[0209] Examples of different kinds of suitable size reducing processes and equipment as stand-alone or coupled together include air swept mills, knife cutting, fine grinders that can have multiple grinding zones with internal classification systems, choppers with finer knives at the end, disintegrators that can handle shredding of textiles even high moisture feeds and then optional fine cutting or milling into smaller size such as a powder, high speed cutting blades that can have multiple zones for moving coarser material to finer material. The size reducing equipment can also include drying before cutting or simultaneous with drying.

[0210] In one embodiment or in combination with any of the mentioned embodiments, at least a portion or all of the size reduced textiles in a feedstock composition fed to a gasifier are obtained from textiles or contain textile fibers. In one embodiment or in combination with any of the mentioned embodiments, the size reduced textiles contain, or as fed to a gasifier or a feedstock to a gasifier contain, at least 10 wt.%, or at least 15 wt.%, or at least 20 wt.%, or at least 25 wt.%, or at least 30 wt.%, or at least 35 wt.%, or at least 40 wt.%, or at least 45 wt.%, or at least 50 wt.%, or at least 55 wt.%, or at least 60 wt.%, or at least 65 wt.%, or at least 70 wt.%, or at least 75 wt.%, or at least 80 wt.%, or at least 85 wt.%, or at least 90 wt.%, or at least 95 wt.% or at least 97 wt.% or at least 98 wt.% or at least 99 wt.% or at least 99.5 wt.% material obtained from textiles or textile fibers, based on the weight of the size reduced textiles feedstock.

[0211] In one embodiment or in combination with any of the mentioned embodiments, which includes size reduced textiles obtained from textiles or containing textile fibers, at least 20%, or at least 30%, or at least 50%, or at least 75%, or at least 80%, or at least 90%, or at least 95%, or at least 98% of the fibers in the textiles feedstock have an aspect ratio L:D of at least 1.5:1 , or at least 1.75:1 , or at least 2:1 , or at least 2.25:1 , or at least 2.5:1 , or at least 2.75:1 , or at least 3:1 , or at least 3.25:1 , or at least 3.5:1 , or at least 3.75:1 , or at least 4:1 , or at least 4.5:1 , or at least 5:1 , or at least 5.5:1 , or at least 6:1.

[0212] Non-combustible inorganic matter such as metals and minerals that prevent the size reduced textiles from being incinerated and emitted may be contained in the size reduced textiles for gasification. Examples include tin, cobalt, manganese, antimony, titanium, sodium, calcium, sulfur, zinc, and aluminum, their oxides and other compounds thereof may be present in the size reduced textiles because a gasifier, and especially slagging gasifiers, are well equipped to handle minerals and metals in a feedstock. Advantageously, titanium and calcium that may be present in the size reduced textiles can be slag modifiers.

[0213] In one embodiment or in combination with any of the mentioned embodiments, the amount of calcium compounds present in the ash of size reduced textiles are at least 30 wt.%, or at least 40 wt.%, or at least 50 wt.%, or at least 55 wt.%, or at least 60 wt.%, or at least 63 wt.%, based on the weight of size reduced textiles ash. The upper amount is desirably not more than 90 wt.%, or not more than 80 wt.%, or not more than 75 wt.%, based on the weight of size reduced textiles ash.

[0214] In another embodiment, the amount of sodium compounds present in the ash of size reduced textiles are at least 2 wt.%, or at least 3 wt.%, or at least 4 wt.%, or at least 5 wt.%, or at least 6 wt.%, or at least 7 wt.%, based on the weight of the size reduced textiles ash. The upper amount is desirably not more than 20 wt.%, or not more than 17 wt.%, or not more than 15 wt.%, based on the weight of size reduced textiles ash.

[0215] In another embodiment, the amount of titanium compounds present in the ash of size reduced textiles are at least 30 wt.%, or at least 40 wt.%, or at least 50 wt.%, or at least 60 wt.%, or at least 70 wt.%, or at least 75 wt.%, based on the weight of size reduced textiles ash. The upper amount is desirably not more than 96 wt.%, or not more than 90 wt.%, or not more than 86 wt.%, based on the weight of the size reduced textiles ash. [0216] In another embodiment, the amount of iron compounds present in the ash of size reduced textiles used in the feedstock is at least 1.5 wt.%, or at least 2 wt%, based on the weight of size reduced textiles ash.

[0217] In another embodiment, the amount of aluminum compounds present in the ash of size reduced textiles used in the feedstock is at least 2 wt.%, or at least 3 wt.%, or at least 5 wt.%, or at least 10 wt.%, based on the weight of the size reduced textiles ash.

[0218] In another embodiment, the amount of silicon compounds present in the ash of size reduced textiles used in the feedstock is at least 2 wt.%, or at least 5 wt.%, or at least 10 wt.%, or at least 15 wt.%, based on the weight of the size reduced textiles ash.

[0219] Desirably, the size reduced textiles contain low levels or no halide containing polymers, in particular polyvinyl chloride, polyvinyl fluoride, polyvinylidene fluoride, and polytetrafluoroethane, and other fluorinated or chlorinated polymers, especially if the size reduced textiles are fed to a refractory line gasifier. The release of chlorine or fluorine elements or radicals over time can impact the longevity of refractory lining on gasifiers operating at high temperature and pressure. In one embodiment or in combination with any of the mentioned embodiments, the size reduced textiles contain less than 10 wt.%, or not more than 8 wt.%, or not more than 6 wt.%, or not more than 5 wt.%, or not more than 4 wt.%, or not more than 3.5 wt.%, or not more than 3 wt.%, or not more than 2.5 wt.%, or not more than 2 wt.%, or not more than 1.5 wt.%, or not more than 1 wt.%, or not more than 0.5 wt.%, or not more than 0.25 wt.%, or not more than 0.1 wt.%, or not more than 0.05 wt.%, or not more than 0.01 wt.%, or not more than 0.005 wt.%, or not more than 0.001 wt.%, or not more than 0.0005 wt.%, or not more than 0.0001 wt.%, or not more than 0.00005 wt.% halide containing polymers, based on the weight of the size reduced textiles. Desirably, the halide minimized or excluded is chlorine or fluorine.

[0220] The size reduced textiles, as a co-fuel in a feedstock composition, have the advantage of not requiring thermal treatment beyond drying prior to their introduction into the gasification zone or their introduction to one or more components of a feedstock composition. Unlike wood or grain which typically requires a thermal treatment, beyond drying, such as torrefaction, the size reduced textiles are desirably not pyrolyzed or torrefied prior to their introduction into the gasifier, and desirably, the size reduced textiles are not obtained from a source of size reduced textiles which have been pyrolyzed or torrefied.

[0221] In another embodiment, the size reduced textiles are not thereafter melted or extruded prior to their entry into the gasifier. In another

embodiment, the size reduced textiles are not softened by heat, melted or extruded or do not receive a pyrolysis thermal treatment, or do not receive a thermal treatment above 225°C, or above 210°C, or above 200°C, or above 195°C, or above 190°C, or above 175°C, or above 160°C, or above 150°C, or above 140°C, or above 130°C, or above 120°C, or above 1 10°C, or above 100°C, or above 90°C, or above 80°C, or above 60°C, or above 58°C or above their nominal temperature at their ambient conditions prior to their introduction into the gasification zone. It is to be noted that the size reduced textiles can be dried before their combination with a fuel for gasification or before their introduction into a gasifier, however, this would not be necessary in a slurry-based feedstock composition such as in water, or a petroleum- based oil, hydrocarbon or oxygenated hydrocarbon fuel feedstock.

[0222] In embodiments, the total amount of carbon in the size reduced textiles are at least 60 wt.%, or at least 65 wt.%, or at least 70 wt.%, or at least 75 wt.%, or at least 80 wt.%.

[0223] In embodiments, the total amount of hydrogen in the size reduced textiles are desirably at least 5 wt.%, or at least 8 wt.%, or at least 10 wt.%.

[0224] In another embodiment, the ratio of total hydrogen to total carbon in the size reduced textiles feed is higher than that of the other source of fuel. In one embodiment or in combination with any of the mentioned embodiments, the ratio of total hydrogen to total carbon in the size reduced textile used in the gasifier feedstock is at least 0.075, or at least 0.08, or at least 0.085, or at least 0.09, or at least 0.095, or at least 0.1 , or at least 0.1 1 , or at least 0.12, or at least 0.13 by weight.

[0225] In another embodiment, the size reduced textiles used in the feedstock composition have an average fixed carbon content of less than 75 wt.%, or not more than 70 wt.%, or not more than 65 wt.%, or not more than 60 wt.%, or not more than 55 wt.%, or not more than 45 wt.%, or not more than 40 wt.%, or not more than 35 wt.%, or not more than 30 wt.%, or not more than 25 wt.%, or not more than 20 wt.%, or not more than 15 wt.%, or not more than 10 wt.%, or not more than 8 wt.%, or not more than 6 wt.%, or not more than 5 wt.%, or not more than 4 wt.%, or not more than 3 wt.%, or not more than 2 wt.%, or not more than 1 wt.%, based on the weight of the size reduced textiles. The fixed carbon content is the combustible solids remaining (other than ash) after the material is heated and volatiles removed. It can be determined by subtracting the percentages of moisture, volatile matter, and ash from a sample.

[0226] If a large amount of size reduced textiles is employed, which have a large mismatch in fixed carbon content compared to the fossil fuel used, variations in the syngas composition can be experienced outside of desirable limits. For example, the size reduced textiles that has a very low fixed carbon content could, in an entrainment flow high temperature gasifier, gasify more readily than coal and proceed to generate more carbon dioxide within the residence time experienced by coal, while a co-feed of solids having a much higher fixed carbon content that coal would take longer to gasify and generate more unconverted solids. The degree of syngas compositional variations that can be tolerated will depend on the use of the syngas, and in the case of making chemicals, it is desirably to minimize the factors that could cause wider size reduced textile derived syngas compositional variations. In the process, size reduced textile derived syngas compositional variations attributable to the use of sized reduced textiles can be negligible by keeping the size reduced textiles concentration in the solids low. [0227] The amount of sized reduced textiles present in the feedstock stream are up to 25 wt.%, or up to 20 wt.%, or up 15 wt.%, or up to 12 wt.%, or up to 10 wt.%, or up to 7 wt.%, or up to 5 wt.%, or less than 5 wt.% based on the weight of the solids in the fuel feedstock stream or composition, or can range from 0.1 wt.% to 25 wt.%, or from 0.1 wt.% to 20 wt.%, or from 0.1 wt.% to 15 wt.%, or from 0.1 wt.% to 12 wt.%, or from 0.1 wt.% to 7 wt.%, or from 0.1 wt.% to 5 wt.%, or from 0.1 wt.% to less than 5 wt.%, or from 0.1 wt.% to 4 wt.%, or from 0.1 wt.% to 3 wt.%, or from 0.1 wt.% to 2.5 wt.%, or from 0.1 wt.% to 2 wt.%, or from 0.1 wt.% to less than 2 wt.%, or from 0.1 wt.% to 1.5 wt.%, 0.5 wt.% to 25 wt.%, or from 0.5 wt.% to 20 wt.%, or from 0.5 wt.% to 15 wt.%, or from 0.5 wt.% to 12 wt.%, or from 0.5 wt.% to 7 wt.%, or from 0.5 wt.% to 5 wt.%, or from 0.5 wt.% to less than 5 wt.%, or from 0.5 wt.% to 4 wt.%, or from 0.5 wt.% to 3 wt.%, or from 0.5 wt.% to 2.5 wt.%, or from 0.5 wt.% to 2 wt.%, or from 0.5 wt.% to less than 2 wt.%, or from 0.5 wt.% to 1.5 wt.%, 1 wt.% to 25 wt.%, or from 1 wt.% to 20 wt.%, or from 1 wt.% to 15 wt.%, or from 1 wt.% to 12 wt.%, or from 1 wt.% to 7 wt.%, or from 1 wt.% to 5 wt.%, or from 1 wt.% to less than 5 wt.%, or from 1 wt.% to 4 wt.%, or from 1 wt.% to 3 wt.%, or from 1 wt.% to 2.5 wt.%, or from 1 wt.% to 2 wt.%, or from 1 wt.% to less than 2 wt.%, or from 1 wt.% to 1.5 wt.%, in each case based on the weight of all fuel feedstock fed to the gasifier, whether solid or liquid, or alternatively based on the weight of all solids in the feedstock stream or composition fed to the gasifier or in the gasification zone. Since sized reduced textiles have, on average, a much lower fixed carbon content than fossil fuels, the amount of carbon dioxide they generate will be more than that of the fossil fuels at the same residence time as the fossil fuels in the gasification zone and on the same weight basis. Desirably, the amount of the size reduced textiles is low to obtain the advantage of minimizing an increase of carbon dioxide content over that generated by the fossil fuels alone. For example, the amount of size reduced textiles relative to all sources of fuel (solid, liquid or gas), or relative to solids, fed to the gasifier is not more than 10 wt.%, or not more than 9 wt.%, or not more than 8 wt.%, or not more than 7 wt.%, or not more than 8 wt.%, or not more than 5 wt.%, or not more than 4 wt.%, or not more than 3.5 wt.%, or not more than 3 wt.%, or not more than 2.75 wt.%, or not more than 2.5 wt.%, or not more than 2.25 wt.%, or not more than 2 wt.%, or not more than 1.75 wt.%, or not more than 1.5 wt.%, or not more than 1.25 wt.%, or not more than 1 wt.%, based on the weight of all gasifier fuel fed to the gasifier (and fuel does not include the oxidizer, steam, water, or carbon dioxide gas), or based on the weight of all solids fed.

Examples of the content of size reduced textiles present in the feedstock composition include 0.25 wt.% to less than 5 wt.%, or from 0.25 wt.% to 4 wt.%, or from 0.25 wt.% to 3 wt.%, or from 0.25 wt.% to 2.5 wt.%, or from 0.5 wt.% to 5 wt.%, or from 0.5 wt.% to 4 wt.%, or from 0.5 wt.% to 3 wt.%, or from 0.5 wt.% to 2.5 wt.%, or from 1 wt.% to 5 wt.%, or from 1 wt.% to 4 wt.%, or from 1 wt.% to 3 wt.%, or from 1 wt.% to 2.5 wt.% each based on the weight of the fuel or solids in the feedstock composition.

[0228] In another embodiment, the size reduced textiles used in the gasifier feedstock composition have an average fixed carbon content that is at least 3% less, or at least 5 % less, or at least 7 % less, or at least 9 % less, or at least 10 % less, or at least 13 % less, or at least 15 % less, or at least 17 % less, or at least 20 % less, or at least 23 % less, or at least 25 % less, or at least 27 % less, or at least 30 % less, or at least 32 % less, or at least 35 % less, or at least 38 % less, or at least 40 % less, or at least 43 % less, or at least 45 % less, or at least 47% less, or at least 50 % less, or at least 55 % less, or at least 60 % less, or at least 70 % less, or at least 80 % less, or at least 90 % less, or at least 95 % less, than the fixed carbon content of coal, or optionally all solid fossil fuel employed in the feedstock composition, or optionally any solids other than size reduced textiles, or any other fuel fed to the gasifier.

[0229] The size reduced textiles can have an average sulfur content that is fairly sizable since high temperature or slagging gasifiers are well equipped to handle sulfur, although in practice textiles have a very low or only trace amounts of sulfur. The size reduced textiles can have an average sulfur content of up to 1 wt.%, or up to 0.5 wt.%, or up to 0.25 wt.%, or up to 0.1 wt.%, or up to 0.05 wt.%, or up to 0.01 wt.%, or up to 0.005 wt.%, or up to 0.0001 wt.%, based on the weight of the size reduced textiles.

[0230] The size reduced textiles may have a widely varying ash content depending on the type of textile they are made from and the purity the size reduced textiles stream to the select size reduced textiles. The size reduced textiles may have an average ash content of at least 1 wt.%, or at least 2 wt.%, or at least 3 wt.%, or at least 4 wt.%, or at least 5 wt.%, or at least 5.5 wt.%, or at least 6 wt.%, or at least 7 wt.%, or at least 10 wt.%, or at least 15 wt.%, or at least 20 wt.%, or at least 25 wt.%, or at least 30 wt.%, or at least 35 wt.%, or at least 40 wt.%, or at least 45 wt.% based on the weight of the size reduced textiles. The size reduced textiles may have an average ash content of not more than 60 wt.%, or not more than 55 wt.%, or not more than 55 wt.%, or not more than 55 wt.%, or not more than 55 wt.%, or not more than 40 wt.%, or not more than 30 wt.%, or not more than 20 wt.%, or not more than 15 wt.%, or not more than 10 wt.%, desirably not more than 8 wt.%, or not more than 7 wt.%, or not more than 6 wt.%, or not more than 5.5 wt.%, or not more than 5 wt.%, or not more than 4.5 wt.%, or not more than 4 wt.%, or not more than 3 wt.%, or not more than 2.5 wt.%, based on the weight of the size reduced textiles.

[0231] In another embodiment, the average oxygen content in the size reduced textiles can be at zero or at least 0.1 wt.%, or at least 0.5 wt.%, or at least 1 wt.%, or at least 2 wt.%, or at least 4 wt.%, or at least 6 wt.%, or at least 8 wt.%, or at least 10 wt.%, or at least 13 wt.%, or at least 15 wt.%, or at least 18 wt.%, or at least 20 wt.%, based on the weight of the size reduced textiles. Desirably, to improve the HHV, the amount of oxygen is kept low, such as not more than 20 wt.%, or not more than 15 wt.%, or not more than 10 wt.%, or not more than 8 wt.%, or not more than 5 wt.%, or not more than 4 wt.%, or not more than 2 wt.%, or not more than 1 wt.%, based on the weight of the size reduced textiles. [0232] The content of minerals, metals and elements other than carbon, hydrogen, oxygen, nitrogen, and sulfur, in the size reduced textiles can be at least 0.01 wt.%, or at least 0.1 wt.%, or at least 0.5 wt.%, or at least 1 wt.%, or at least 1.5 wt.%, or at least 1.8 wt.%, or at least 2 wt.%, or at least 2.3 wt.%, or at least 2.5 wt.%, or at least 2.8 wt.%, or at least 3 wt.%, based on the weight of the size reduced textiles. The upper amount is not particularly limited, and generally would not exceed 8 wt.%, or not exceed 7 wt.%, or not exceed 6 wt.%, or not exceed 5 wt.%, or not exceed 4.5 wt.%, or not exceed 4 wt.%, or not exceed 3.8 wt.%.

[0233] The size of the size reduced textiles is desirably not larger than the maximum size the gasifier in use can accept. Many coal fed gasifiers can grind or mill the coal to a desired size before feeding them to the gasification zone. Relying upon such grinding or milling operations to achieve the desired size reduced textiles particle size is not advisable since such solid fossil fuel mills do not cut but rather crush and grind and would not be an effective means to further size reduce the textiles. Accordingly, the size of the size reduced textiles is desirably not larger than the target size to be fed to the gasifier prior to combining them with a fuel feed to a gasifier or prior to adding them to a liquid fed to a gasifier.

[0234] The actual particle size of the size reduced textiles can vary with the type of gasifier used. For example, size reduced textiles having an average size of 1/4 inch or less in their largest dimension cannot be

processed through an entrained flow coal gasifier. However, fixed bed or moving bed gasifiers can accept larger particle sizes. Examples of suitable sizes of size reduced textiles fed to a fixed bed or moving bed gasifier are not more than 12 inches, or not more than 8 inches, or not more than 6 inches, or not more than 5 inches, or not more than 4 inches, or not more than 3.75 inches, or not more than 3.5 inches, or not more than 3.25 inches, or not more than 3 inches, or not more than 2.75 inches, or not more than 2.5 inches, or not more than 2.25 inches, or not more than 2 inches, or not more than 1.75 inches, or not more than 1.5 inches, or not more than 1.25 inches. The size can be at least 2mm, or at least 1/8 inches, or at least ¼ inches, or at least ½ inches, or at least 1 inch, or at least 1.5 inches, or at least 1.75 inches, or at least 2 inches, or at least 2.5 inches, or at least 3 inches, or at least 3.5 inches, or at least 4 inches, or at least 4.5 inches, or at least 5 inches, or at least 5.5 inches. Such relatively large size reduced textiles are better suited for use in fixed or moving bed gasifiers, especially those that are updraft fixed or moving bed gasifiers.

[0235] With many gasifier designs, the fossil fuel (coal or petcoke) and the size reduced textiles are size reduced for multiple purposes. The size reduced textiles are of a small size as is the fossil fuel source to (i) allow for faster reaction once inside the gasifier due to mass transfer limitations, (ii) to create a slurry that is stable, fluid and flowable at high concentrations of solids to water in slurry fed gasifiers, (iii) to pass through processing equipment such as high-pressure pumps, valves, and feed injectors that have tight clearances,

(iv) to flow through screens between the mills or grinders and the gasifier, or

(v) to be conveyed with gases used for conveying solid fossil fuels to dry fed gasifiers.

[0236] In one embodiment or in combination with any of the mentioned embodiments, the size reduced textile particle sizes are desirably not more than 5 inches, or not more than 4 inches, or not more than 1 inch, or not more than ¼ inch, or not more than 2 mm. The larger sizes are useful for addition to a fixed bed or moving bed gasifier, particularly in updraft gasifiers to provide sufficient density to allow them to contact the bed as a solid that has not fully charred or be converted to ash.

[0237] In embodiments, the solids in the gasifier feedstock, including the size reduced textiles, have a particle size of 2 mm or smaller. This

embodiment is particularly attractive to entrained flow gasifiers, including dry feed and slurry fed gasifiers, and to fluidized bed gasifiers. As used

throughout, unless a different basis is expressed (e.g. a mean), a stated size means that at least 90 wt.% of the size reduced textiles have a largest dimension in the stated size, or alternatively that 90 wt.% of the size reduced textiles pass through sieve designated for that particle size. Either conditions satisfy the particle size designation. Size reduced textiles sized larger than 2 mm for an entrained flow gasifier have the potential for being blown through the gasification zone of entrained flow gasifiers without completely gasifying, particularly when the gasification conditions are established to gasify solid fossil fuel having a particle dimension of 2 mm or smaller. Smaller sized textiles are desirable in a fluidized bed reactor to more easily fluidize the textiles in the oxidizer stream of gas.

[0238] In embodiments, the size of the size reduced textiles as such or as combined with a fossil fuel, or in the gasifier feed, or injected into the gasification zone, is 2 mm or smaller or constitute those particles passing through a 10 mesh, or 1.7 mm or smaller (those particles passing through a 12 mesh), or 1.4 mm or smaller (those particles passing through a 14 mesh), or 1.2 mm or smaller (those particles passing through a 16 mesh), or 1 mm or smaller (those particles passing through a 18 mesh), or 0.85 mm or smaller (those particles passing through a 20 mesh), or 0.7 mm or smaller (those particles passing through a 25 mesh) or 0.6 mm or smaller (those particles passing through a 30 mesh), or 0.5 mm or smaller (those particles passing through a 35 mesh), or 0.4 mm or smaller (those particles passing through a 40 mesh), or 0.35 mm or smaller (those particles passing through a 45 mesh), or 0.3 mm or smaller (those particles passing through a 50 mesh), or 0.25 mm or smaller (those particles passing through a 60 mesh), or 0.15 mm or smaller (those particles passing through a 100 mesh), or 0.1 mm or smaller (those particles passing through a 140 mesh), or 0.07 mm or smaller (those particles passing through a 200 mesh), or 0.044 mm or smaller (those particles passing through a 325 mesh), or 0.037 mm or smaller (those particles passing through a 400 mesh). In another embodiment, the size of the size reduced textiles particles is at least 0.037 mm (or 90% retained on a 400 mesh).

[0239] In embodiments, the size reduced textiles have a particle size that, after optional sieving, is acceptable for gasifying within the design parameters of the type of gasifier used. The particle sizes of size reduced textiles and the solid fossil fuels can be sufficiently matched to retain the stability of the slurry and avoid a coal/size reduced textiles separation at high solids concentrations prior to entering the gasification zone in the gasifier. A feedstock composition that phase separates, whether between solids/liquid or solid/solids in a slurry, or solids/solids in a dry feed, or solid/liquid in a liquid feedstock, can plug lines, created localized zones of gasified size reduced textiles, create inconsistent ratios of fossil fuel/size reduced textiles, and can impact the consistency of the syngas composition. Variables to consider for determining the stability of the feedstock composition include setting an optimal particle size of the size reduced textiles, and variables for determining the optimal particle sizes include the bulk density of the ground coal, the concentration of all solids in the slurry if a slurry is used or the solid/solid concentration in a dry feed, the effectiveness of any additives employed such as

surfactants/stabilizers/viscosity modifiers, and the velocity and turbulence of the feedstock composition to the gasifier and through the injector nozzles.

[0240] In one embodiment or in combination with any of the mentioned embodiments, the bulk density of the size reduced textiles is within 150%, or within 1 10%, or within 100%, or within 75%, or within 60%, or within 55%, or within 50%, or within 45%, or within 40%, or within 35% of the bulk density of the ground fossil fuel that is used as a feed introduced to the gasification zone. For example, if the granulated coal has a bulk density of 40 lbs/ft³ and the size reduced textiles have a bulk density of 33 lbs/ft³, the bulk density of the size reduced textiles would be within 21 % of the ground coal. For measurement purposes, the bulk density of the size reduced textiles and the fossil fuel is determined on a dry basis (without addition of water) even if they are ultimately used as a slurry.

[0241] In embodiments, the maximum particle size of the size reduced textiles are selected to be similar (below or above) to the maximum particle size of the ground solid fossil fuel. The maximum particle size of the size reduced textiles used in the gasifier feedstock can be not more than 50% larger than the maximum solid fossil fuel size in the gasifier feedstock, or not more than 45%, or not more than 40%, or not more than 35%, or not more than 30%, or not more than 25%, or not more than 20%, or not more than 15%, or not more than 10%, or not more than 5%, or not more than 3%, or not more than 2%, or not more than 1 % larger than the maximum solid fossil fuel size in the gasifier feedstock, or not larger than, or smaller than the maximum solid fossil fuel size in the gasifier feedstock. Optionally, the maximum particle size of the size reduced textiles used in the gasifier feedstock as stated above can be within (meaning not larger than and not smaller than) the stated values. The maximum particle size is not determined as the maximum size of the particle distribution but rather by sieving through meshes. The maximum particle size is determined as the first mesh which allows at least 90 volume % of a sample of the particles to pass. For example, if less than 90 volume % of a sample passes through a 300 mesh, then a 100 mesh, a 50 mesh, a 30 mesh, a 16 mesh, but succeeds at a 14 mesh, then the maximum particle size of that sample is deemed to correspond to the first mesh size that allowed at least 90 volume % to pass through, and in this case, a 14 mesh corresponding to a maximum particle size of 1.4 mm.

[0242] The size reduced textiles are desirably isolated as size reduced textiles feed for ultimate destination to be fed to a gasifier. In one

embodiment or in combination with any of the mentioned embodiments, at least 80 wt.%, or at least 85 wt.%, or at least 90 wt.%, or at least 95 wt.%, or at least 96 wt.%, or at least 97 wt.%, or at least 98 wt.%, or at least 99 wt.%, or at least 99.5 wt.%, or 100 wt.% of all solid feedstock other than solid fossil fuels and sand fed to the gasifier are size reduced textiles, based on the cumulative weight of all streams containing solids fed to the gasifier.

[0243] The size reduced textiles are optionally sieved, and then combined with one or more fossil fuel components of the feedstock stream at any location prior to introducing the feedstock stream into a gasification zone within the gasifier. Solid fossil fuel grinding equipment will provide an excellent source of energy for mixing size reduced textiles with the solid fossil fuel while reducing the size of the solid fossil fuel particles. Therefore, one of the desirable locations for combining size reduced textiles having a target size for feeding into the gasifier is into the equipment used for grinding the other solid fossil fuel sources (e.g. coal, pet-coke). This location is particularly attractive in a slurry fed gasifier because it is desirable to use a feed having the highest stable solids concentration possible, and at higher solids concentration, the viscosity of the slurry is also high. The torque and shear forces employed in fossil fuel grinding equipment is high, and coupled with the shear thinning behavior of a solid fossil fuel (e.g., coal) slurry, good mixing of the size reduced textiles with the ground fossil fuel can be obtained in the fossil fuel grinding equipment.

[0244] Other locations for combining size reduced textiles with fossil fuel sources can be onto the fossil fuel loaded on the main fossil fuel belt feeding a mill or grinder, or onto the main fossil fuel before the fossil fuel is loaded onto the belt to the mill or grinder, or into a fossil fuel slurry storage tank containing a slurry of fossil fuel ground to the final size, particularly if the storage tank is agitated.

[0245] More particularly, there are several locations that provide a safe, economic and effective way to introduce sized reduced textiles to a slurry fed coal gasifier. In additional embodiments of the invention, Figure 5 shows four locations where post-consumer sized reduced textiles can be introduced. All of these points are in the low-pressure section (lower than the pressure within the gasifier or gasification zone) of the process thus reducing the cost of modifications.

[0246] In an embodiment of the invention shown in Figure 5, the sized reduced textiles can be introduced at location 100, the main fossil fuel belt (e.g. coal feed belt). For purposes of convenience, reference is made to coal in Figure 5 although it is to be understood that any solid fossil fuel can be employed. The sized reduced textiles are metered onto the main coal feed belt as it moves past with the coal already loaded onto the belt. The sized reduced textiles are added to the belt using a weigh belt feeder, or other similar device, to measure the mass of the material, and the speed of the belt to determine addition rate. The coal is similarly added to the same belt and would be underneath the sized reduced textiles. The combined solid mixture of the coal and sized reduced textiles in the proper ratio are then conveyed to surge hoppers and other storage and conveying equipment until it is ultimately fed to the coal grinding mill. In the coal grinding mill, the coal, sized reduced textiles, water and viscosity modifiers are mixed thoroughly, and the coal is reduced in size to the target grind size distribution and the mixture becomes a viscous slurry. The sized reduced textiles undergo very little or no size reduction since it is a softer material, but benefits from the extreme mixing in the mill due to its inclusion into the slurry production process. The sized reduced textiles have been size reduced the same average size as introduced into the gasification zone and do not need any further size reduction after addition to the solid fossil fuel or water used to make the slurry.

[0247] In another embodiment of the invention, sized reduced textiles can be introduced as shown in Figure 5 location number 110. This is the same process as described in location number 100 above, except that the sized reduced textiles are added to the main coal belt first, before the coal is added. In this manner, the coal is on top. Since the sized reduced textiles may have a lower bulk density than coal or other solid fossil fuel, it may be easier for the sized reduced textiles to be blown off of the belt in a strong wind upon deposition or as it moves down the belt, or otherwise when screened. With the more dense solid fossil fuel covering the sized reduced textiles, this dusting and loss of material can be greatly reduced.

[0248] In another embodiment the invention, the sized reduced textiles can be added at location number 120, the grinding mill. The existing equipment, coal, water and viscosity modifiers are already added to the grinding mill to reduce the particle size of the coal or petcoke and produce a viscous slurry high in solids. The sized reduced textiles can be independently conveyed to the entry point of the mill and added directly to the mill in the proper ratio. The mill will then grind the solid fossil fuel, produce the slurry and thoroughly mix in the sized reduced textiles in the process. This avoids wind and weather effects on the coal, recycled material mixture.

[0249] In yet another embodiment of the invention the sized reduced textiles can be introduced at location number 130, the slurry storage tank. Since the sized reduced textiles are pre-ground to the proper particle size for introduction into the gasifier, it can be added to the slurry storage tank directly after the grinding/slurry operation. Alternatively, sized reduced textiles can be added to the tank through a separate screen or the screen used by the slurry to ensure no excessively large sized reduced textiles are passed to the tank. This is the last low-pressure addition point before the slurry is pumped at pressure to the gasifier. This will minimize the amount of material in process that is mixed together. The agitation in the slurry tanks will mix in the sized reduced textiles sized reduced textiles to ensure they are evenly distributed.

[0250] Granulators can be used to obtain the desired size reduction.

These can include systems for shredding the textiles using high capacity shredders, and if necessary, a fine/powder granulator can be used in a last step. For the last step, the fine/powder granulators can be in communication with a conveying system to transport the sized reduced textiles to a storage vessel from which the sized reduced textiles particles can be fed to any location for making the feedstock stream, or the particles can be fed continuously from the fine granulator to the desired location for making the feedstock stream. The feed of granulated sized reduced textiles particles from a storage vessel can be in a batch mode or in a continuous mode.

[0251] In one embodiment or in combination with any mentioned embodiments, the feedstock materials, e.g. fossil fuel and sized reduced textiles are advantageously loose and not densified by mechanical or chemical means after the sized reduced textiles are combined with the solid fossil fuel such as coal (other than natural compaction that may result from storage under its own weight). For example, once sized reduced textiles are contacted with coal, the combination is not densified. [0252] The solid fossil fuel is typically ground to a size of 2 mm or less, and can be ground to any of the sizes noted above with respect to the sized reduced textiles of less than 2 mm. The small size of the coal and sized reduced textiles particles is advantageous to enhance a uniform suspension in the liquid vehicle which will not settle out, to allow sufficient motion relative to the gaseous reactants, to assure substantially complete gasification, and to provide pumpable slurries of high solids content with a minimum of grinding

[0253] In one embodiment or in combination with any of the mentioned embodiments, both size reduced textiles and recycle plastic particles are fed to the gasifier. For example, a single feedstock composition can contain the size reduced textiles and recycle plastic particles, or they may be contained in separate streams fed to the gasifier. In one embodiment or in combination with any of the mentioned embodiments, at least 80 wt.%, or at least 85 wt.%, or at least 90 wt.%, or at least 95 wt.%, or at least 96 wt.%, or at least 97 wt.%, or at least 98 wt.%, or at least 99 wt.%, or at least 99.5 wt.%, or 100 wt.% of all solid feedstock, other than solid fossil fuels, fed to the gasifier is size reduced textiles and recycle plastic particles, based on the cumulative weight of all streams containing solids fed to the gasifier.

[0254] In one embodiment or in combination with any of the mentioned embodiments, the solids fed to the gasifier include a combination of size reduced textile particles and recycle plastic particles as a solid/solid

combination, and desirably also solid fossil fuel particles. The weight ratio of size reduced textiles to recycle plastic particles can be from 1 :99 to 99:1 , or 10:90 to 90:10, or 20:80 to 80:20, or from 30:70 to 70:30.

[0255] If recycle plastic particles are used in combination with the size reduced textiles, the recycle plastic particles are desirably not more than any of the sizes mentioned above applicable to the size reduced textiles.

[0256] The solids in the feedstock composition desirably do not contain sewage sludge, waste paper not already embedded in a thermoplastic matrix, or biomass. In one embodiment or in combination with any of the mentioned embodiments, the feedstock composition contains not more than 10 wt.%, or not more than 6 wt.%, or not more than 5 wt.%, or not more than 4 wt.%, or not more than 3 wt.%, or not more than 2 wt.%, or not more than 1 wt.%, or not more than 0.5 wt.%, or not more than 0.25 wt.%, or not more than 0.1 wt.% of any one of sewage sludge, waste paper not embedded in a

thermoplastic matrix, biomass, or a combination of two or more, each based on the weight of the solids in the feedstock composition.

[0257] The size reduced textiles may contain some level of inorganic materials other than polymer, such as metals, glass (whether in the form of fibers or particles), mineral fillers, and other inorganic materials. The quantity of such materials in the size reduced textiles that feed into the feedstock composition, is desirably less than 8 wt.%, or not more than 6 wt.%, or not more than 5 wt.%, or not more than 4 wt.%, or not more than 3.5 wt.%, or not more than 2 wt.%, or not more than 1.5 wt.%, or not more than 1 wt.%, or not more than 0.75 wt.%, or not more than 0.5 wt.%, based on the weight of the size reduced textiles.

[0258] The amount of solid fossil fuel, such as coal, in the feedstock or fed to the gasifier can be at least 10 wt.%, or at least 80 wt.%, or at least 85 wt.%, or at least 90 wt.%, or at least 93 wt.%, or at least 95 wt.%, or at least 97 wt.%, or at least 98 wt.%, or at least 98.5 wt.%, or at least 99 wt.%, and less than 100 wt.%, or less than 99.5 wt.%, based on the weight of solids in the feedstock.

[0259] Coal contains a quantity of ash that also contains elements other than carbon, oxygen, and hydrogen. The quantity of elements other than carbon, hydrogen, oxygen, and sulfur in the solid fossil fuel, or in the feedstock composition, is desirably not more than 15 wt.%, or not more than 13 wt.%, or not more than 10 wt.%, or not more than 9 wt.%, or not more than 8.5 wt.%, or not more than 8 wt.%, or not more than 7.5 wt.%, or not more than 7 wt.%, or not more than 7.5 wt.%, or not more than 7 wt.%, or not more than 6.5 wt.%, or not more than 6 wt.%, or not more than 5.5 wt.%, or not more than 5 wt.%, or not more than 4.5 wt.%, based on the weight of the solid fossil fuel or alternatively based on the weight of all dry solids in the feedstock composition, or based on the weight of the feedstock composition,

respectively.

[0260] The caloric heat value of size reduced textiles is desirably similar to or better than that of coal. For example, the size reduced textiles can have a heat value of at least 13,000, or at least 13,500, or at least 14,000 BTU/lb, or in the range of 13,000 to 15,000 BTU/lb (30 MJ/Kg - 35 MJ/Kg), while bituminous coal can have a heat value in a range of 12,500 to 13,300 BTU/lb (29 - 31 MJ/Kg). Further, any ash or non-organic material can be melted and vitrified into the ash or slag matrix that is produced from the inorganics in the coal.

[0261] The concentration of solids (e.g. fossil fuel and size reduced textiles) in the feedstock composition should not exceed the stability limits of a slurry or solids/solids mix, or the ability to pump or feed the feedstock at the target solids concentration to the gasifier. Desirably, the solids content of a slurry should be at least 50 wt.%, or at least 55 wt.%, or at least 60 wt.%, or at least 62 wt.%, or at least 65 wt.%, or at least 68 wt.%, or at least 69 wt.%, or at least 70 wt.%, or at least 75 wt.%, the remainder being a liquid phase that can include water and liquid additives. The upper limit is not particularly limited because it is dependent upon the gasifier design. Flowever, given the practical pumpability limits of a solid fossil fuels feed and maintaining a homogeneous distribution of solids in the slurry, the solids content for a solid fossil slurry fed slagging gasifier desirably should not exceed 75 wt.%, or 73 wt.%, the remainder being a liquid phase that can include water and liquid additives (as noted above, gases are not included in the calculation of weight percentages). The solids concentration of a dry fed gasifier is desirably 95 wt.% or more, or 97 wt.% or more, or 98 wt.% or more, or 99 wt.% or more, or 100 wt.%, based on the weight of the gasifier feedstock composition

(excluding the weight of the gas and moisture contained in the solids).

[0262] A slurry feedstock composition is desirably stable at 5 minutes, or even 10 minutes, or even 15 minutes, or even 20 minutes, or even ½ hour, or even 1 hour, or even two hours. A slurry feedstock is deemed stable if its initial viscosity is 100,000 cP or less. The initial viscosity can be obtained by the following method. A 500-600 g of a well-mixed sample is allowed to stand still in a 600 ml_ liter glass beaker at ambient conditions (e.g. 25°C and about 1 atm). A Brookfield R/S Rheometer equipped with V80-40 vane operating at a shear rate of 1.83/s is submerged into the slurry to the bottom of the beaker after the slurry is well mixed (e.g. a homogeneous distribution of solids was formed). After a designated period of time, a viscosity reading is obtained at the start of rotation, which is the initial viscosity reading. The slurry is considered to be stable if the initial reading on starting a viscosity

measurement is not more than 100,000 cP at the designated period of time. Alternatively, the same procedure can be used with a Brookfield viscometer with an LV-2 spindle rotating at a rate of 0.5 rpm. Since different viscosity value will be obtained using the different equipment, the type of equipment used should be reported. However, regardless of the differences, the slurry is considered stable under either method only if its viscosity is not more than 100,000 cP at the reported time.

[0263] The quantity of solids in the feedstock composition and their particle size are adjusted to maximize the solids content while maintaining a stable and pumpable slurry. A pumpable slurry is one which has a viscosity under 30,000 cP, or not more than 25,000 cP, or not more than 23,000 cP, and desirably not more than 20,000 cP, or not more than 18,000 cP, or not more than 15,000 cP, or not more than 13,000 cP, in each case at ambient conditions (e.g. 25°C and 1 atm). At higher viscosities, the slurry becomes too thick to practically pump. The viscosity measurement to determine the pumpability of the slurry is taken by mixing a sample of the slurry until a homogeneous distribution of particles is obtained, thereafter immediately submerging a Brookfield viscometer with an LV-2 spindle rotating at a rate of 0.5 rpm into the well mixed slurry and taking a reading without delay.

Alternatively, a Brookfield R/S rheometer with V80-40 vane spindle operating at a shear rate of 1.83/s can be used. The method of measurement is reported since the measured values between the two rheometers at their difference shear rates will generate different values. However, the cP values stated above apply to either of the rheometer devices and procedures.

[0264] In embodiments, the slurry feedstock composition has a viscosity of 80,000 cP or less, or 70,000 cP or less, or 60,000 cP or less, 50,000 cP or less, or 40,000 cP or less, or 35,000 cP or less, or 25,000 cP or less, or 20,000 cP or less, or 15,000 cP or less, or 10,000 cP or less, in each case, at 5 minutes, or even 10 minutes, or even 15 minutes, or even 20 minutes, desirably at 5 minutes or at 20 minutes, or at 20 minutes and desirably at 60,000 cP or less or 40,000 cP or less.

[0265] In embodiments, the fossil fuel is at least coal. The quality of the coal employed is not limited. Anthracite, bituminous, sub-bituminous, brown coal, and lignite coal can be sources of coal feedstock. To increase the thermal efficiency of the gasifier, the coal employed desirably has a carbon content that exceeds 35 wt.%, or at least 42 wt.%, based on the weight of the coal. Accordingly, bituminous or anthracite coal is desirable due to their higher energy content.

[0266] Sulfur is also typically present in solid fossil fuels. Desirably, the content of sulfur is less than 5 wt.%, not more than 4 wt.%, or not more than 3 wt.%, or not more than 2.5 wt.%, and also can contain a measure of sulfur, such as at least 0.25 wt.%, or at least 0.5 wt.%, or at least 0.75 wt.%, based on the weight of the solid fossil fuel.

[0267] It is also desirable to employ a solid fossil fuel with a low inherent moisture content to improve the thermal efficiency of the gasifier. Using coal having moisture contents less than 25 wt.% or less than 20 wt.% or less than 15 wt.% or not more than 10 wt.% or not more than 8 wt.% is desirable to improve the energy efficiency of the gasifier.

[0268] Desirably, the coal feedstock has a heat value of at least 1 1 ,000 BTU/lb, or at least 1 1 ,500 BTU/lb, or at least 12,500 BTU/lb, or at least 13,000 BTU/lb, or at least 13,500 BTU/lb, or at least 14,000 BTU/lb, or at least 14,250 BTU/lb, or at least 14,500 BTU/lb. [0269] In a slurry fed gasifier, while it is possible that the feedstock composition may contain minor amounts of liquid hydrocarbon oils leached from size reduced textiles or coal, the feedstock composition desirably contains less than 5 wt.%, or not more than 3 wt.%, or not more than 1 wt.%, or not more than 0.1 wt.% liquid (at ambient conditions) non-oxygenated hydrocarbon petroleum oils introduced as such into the feedstock

composition. Desirably, the feedstock composition contains less than 2 wt.%, or not more than 1 wt.%, or no added liquid fraction from refining crude oil or reforming any such fraction in a slurry feedstock stream or to a slurry fed gasifier.

[0270] In a slurry gasifier feedstock, the content of liquids, or the content of water, present in the feedstock composition is desirably not more than 50 wt.%, or not more than 35 wt.%, or not more than 32 wt.%, or not more than 31 wt.%, or not more than 30 wt.%, based on the weight of the feedstock composition. Desirably, in each case, the content of liquids or water in the feedstock composition for a slurry fed gasifier is desirably at least 10 wt.%, or at least 15 wt.%, or at least 20 wt.%, or at least 25 wt.%, or at least 27 wt.%, or at least 30 wt.%, based on the weight of the feedstock composition. The liquids present in the slurry gasifier feedstock desirably contain at least 95 wt.% water, or at least 96 wt.% water, or at least 97 wt.% water, or at least 98 wt.% water, or at least 99 wt.% water, based on the weight of all liquids fed to the gasifier. In another embodiment, other than chemical additives that are chemically synthesized and contain oxygen or sulfur or nitrogen atoms, the liquid content of the feedstock composition is at least 96 wt.% water, or at least 97 wt.% water, or at least 98 wt.% water, or at least 99 wt.% water, based on the weight of all liquids fed to the gasifier.

[0271] In embodiments, at least a portion of the fuel feedstock to the gasifier is a liquid at 25°C and 1 atmosphere, such as organic feedstocks, petroleum oils or fractions from refining or distilling crude oil, hydrocarbons, oxygenated hydrocarbons, or synthetic chemical compounds. These liquid feedstocks can be from any fraction from petroleum distillation or refining, or any chemical synthesized at a chemical manufacturing facility, provided they are liquid. These liquids are a carbon fuel source for gasifying into syngas. In one embodiment or in combination with any of the mentioned embodiments, there is now also provided a combination of size reduced textiles and a hydrocarbon liquid fuel or oxygenated hydrocarbon liquid fuel that are liquid at 25°C and 1 atmosphere. Depending on the nature of the liquid fuel feedstock, the size reduced textiles may be insoluble, partially soluble, or soluble in the liquid fuel feedstock.

[0272] In an embodiment, the water present in the feedstock stream is not wastewater, or in other words, the water fed to the solids to make the feedstock stream is not wastewater. Desirably, the water employed has not been industrially discharged from any process for synthesizing chemicals, or it not municipal wastewater. The water is desirably fresh water, or potable water.

[0273] In embodiments, the feedstock stream comprises at least ground coal and sized reduced textiles. Desirably, the feedstock stream also comprises water. The amount of water in the feedstock stream can range from 0 wt.% up to 50 wt.%, or from 10 wt.% to 40 wt.%, or from 20 wt.% to 35 wt.%. The feedstock stream is desirably a slurry containing water.

[0274] In addition to solid fossil fuel and size reduced textiles, other additives can be added to and contained in the feedstock composition, such as viscosity modifiers and pH modifiers. The total quantity of additives can range from 0.01 wt.% to 5 wt.%, or from 0.05 wt.% to 5 wt.%, or from 0.05 to 3 wt.%, or from 0.5 to 2.5 wt.%, based on the weight of the feedstock

composition. The quantity of any individual additive can also be within these stated ranges.

[0275] The viscosity modifiers (which includes surfactants) can improve the solids concentration in a slurry gasifier feedstock. Examples of viscosity modifiers include:

(i) alkyl-substituted amine-based surfactant such as alkyl- substituted aminobutyric acid, alkyl-substituted polyethoxylated amide, and alkyl-substituted polyethoxylated quaternary ammonium salt; and

(ii) sulfates such as salts of organic sulfonic acids including ammonium, calcium and sodium sulfonates, particularly those with lignin and sulfo-alkylated lignites;

(iii) phosphate salts;

(iv) polyoxyalkylene anionic or nonionic surfactants.

[0276] More specific examples of alkyl-substituted aminobutyric acid surfactants include N-coco-beta-aminobutyric acid, N-tallow-beta- aminobutyric acid, N-lauryl-beta-aminobutyric acid, and N-oleyl-beta- aminobutyric acid. N-coco-beta-aminobutyric acid.

[0277] More specific examples of alkyl-substituted polyethoxylated amide surfactant include polyoxyethylene oleamide, polyoxyethylene tallowamide, polyoxyethylene laurylamide, and polyoxyethylene cocoamide, with 5-50 polyoxyethylene moieties being present.

[0278] More specific examples of the alkyl-substituted polyethoxylated quaternary ammonium salt surfactant include methylbis (2-hydroxyethyl) cocoammonium chloride, methylpolyoxyethylene cocoammonium chloride, methylbis (2-hydroxyethyl) oleylammonium chloride, methylpolyoxyethylene oleylammonium chloride, methylbis (2-hydroxyethyl) octadecylammonium chloride, and methylpolyoxyethylene octadecylammonium chloride.

[0279] More specific examples of sulfonates include sulfonated

formaldehyde condensates, naphthalene sulfonate formaldehyde

condensates, benzene sulfonate - phenol - formaldehyde condensates, and lingosulfonates.

[0280] More specific examples of phosphate salts include trisodium phosphate, potassium phosphate, ammonium phosphate, sodium

tripolyphosphate or potassium tripolyphosphate.

[0281] Examples of polyoxyalkylene anionic or nonionic surfactants have 1 or more repeating units derived from ethylene oxide or propylene oxide, or 1 - 200 oxyalkylene units. [0282] Desirably, the surfactant is an anionic surfactant, such as salts of an organic sulfonic acid. Examples are calcium, sodium and ammonium salts of organic sulfonic acids such as 2,6-dihydroxy naphthalene sulfonic acid, lignite sulfonic acid, and ammonium lignosulfonate.

[0283] Examples of pH modifiers include aqueous alkali metal and alkaline earth hydroxides such as sodium hydroxide, and ammonium compounds such as 20-50 wt.% aqueous ammonium hydroxide solutions. The aqueous ammonium hydroxide solution can be added directly to the feedstock composition prior to entry into the gasifier, such as in the coal grinding equipment or any downstream vessels containing the slurry.

[0284] In embodiments, the atomic ratio of total oxygen to carbon entering the gasification zone can be a value in the range of 0.70 to less than 2, or from 0.9 to 1.9, or from 0.9 to 1.8, or from 0.9 to 1.5, or from 0.9 to 1.4, or from 0.9 to 1.2, or from 1 to 1.9, or from 1 to 1.8, or from 1 to 1.5, or from 1 to 1.2, or from 1.05 to 1.9, or from 1.05 to 1.8, or from 1.05 to 1.5, or from 1.05 to 1.2. The atomic ratio of free oxygen to carbon entering the gasification zone can also be within these same values. The weight ratio of both total oxygen and free oxygen to carbon in pounds entering the gasification zone can also each be within these stated values.

[0285] In embodiments, the total carbon content in the feedstock composition is at least 40 wt.%, or at least 45 wt.%, or at least 50 wt.%, or at least 55 wt.%, or at least 60 wt.%, or at least 65 wt.%, and desirably at least 70 wt.%, or at least 75 wt.%, or at least 80 wt.%, or at least 85 wt.%, or at least 90 wt.%, each based on the total solids content.

[0286] In embodiments, the gasifier feedstock composition is desirably injected along with an oxidizer into a refractory-lined combustion chamber (gasification zone) of the synthesis gas generating gasifier. The feedstock stream (desirably a slurry) and oxidizer are desirably sprayed through an injector into a gasification zone. The gasification zone can be under significant pressure, typically about 500 psig or more, or 600 psig or more, or 800 psig or more, or 1000 psig or more. For an entrained flow gasifier, the velocity or flow rate of the feedstock and oxidizer streams ejected from the injector nozzle into the gasification zone (or combustion chamber) will exceed the rate of flame propagation to avoid backflash.

[0287] In embodiments, advantageously only one feedstock composition is charged to the gasifier or gasification zone, or in other words, all sources of carbon fuel are fed to the gasifier in only one stream.

[0288] In one embodiment or in combination with any of the mentioned embodiments, only one feedstock stream is necessary or employed to produce a size reduced textile derived syngas or product stream that is a raw material to synthesize a chemical compound.

[0289] In another embodiment, a chemical made from a first size reduced textile derived syngas sourced from a first gasifier fed with a first feedstock composition containing a solid fossil fuel is not combined with a second syngas stream sourced from any other gasifier fed with second fossil fuel feedstock composition where the solid fossil fuel content between the first and second feedstock compositions differ by more than 20%, or more than 10%, or more than 5%, based on the weight of the all solids fed to the gasifiers. For example, a first syngas stream generated from a first feedstock composition containing 90 wt.% coal would not be combined with a syngas stream generated from a different gasifier fed with a feedstock composition containing 70 wt.% coal or no coal, but could be combined with one containing 72 wt.% coal or more.

[0290] In another embodiment, a first syngas sourced from a first gasifier fed with a first feedstock composition containing a first fixed carbon content is not combined with a second syngas stream sourced from any other gasifier fed with a second feedstock containing a second fixed carbon content, where the difference between the first and second fixed carbon contents is more than 20%, or more than 10%, or more than 5% of each other, based on the weight of the all solids fed to the gasifiers. For example, a first syngas stream generated from a first feedstock composition containing 70 wt.% fixed carbon based on the weight of the solids would not be combined with a syngas stream generated from a different gasifier fed with a feedstock composition containing 30 wt.% fixed carbon, but could be combined with one containing 56 wt.% fixed carbon if the limit of 20% is selected.

[0291] Prior to entry into the gasifier, the feedstock composition may be subjected to a variety of other optional processes. For example, a slurry can flow through a thickener in which excess water is eliminated from the slurry to obtain the final desired solids concentration of the slurry entering into the gasifier vessel. The feedstock composition may be pre-heated to prior to entry into the gasifier. In this embodiment, a slurry feedstock composition is heated to a temperature below the boiling point of water at the operating pressure existing in reaction zone. The preheater, when employed, reduces the heat load on the gasifier and improves the efficiency of utilization of both fuel and oxygen.

[0292] In one embodiment or in combination with any of the mentioned embodiments, at least 80 wt.% of all of the water required for the generation of synthesis gas in reaction zone is supplied in liquid phase. When petroleum coke is employed as fuel for the gas generator, part of the water, e.g., from 1 to about 90 percent by weight based on the weight of water, may be vaporized in the slurry feed preheater or combined with the oxidizing stream as vaporized water.

[0293] The oxidizer is desirably an oxidizing gas that can include air, and desirably is a gas enriched in oxygen at quantities greater than that found in air. The reaction of oxygen and solid fossil fuel is exothermic. Desirably, the oxidant gas contains at least 25 mole% oxygen, or at least 35 mole%, or at least 40 mole%, or at least 50 mol%, or at least 70 mole%, or at least 85 mole%, or at least 90 mole%, or at least 95 mole%, or at least 97 mole%, or at least 98 mole% oxygen, or at least 99 mole%, or at least 99.5 mole% based on all moles in the oxidant gas stream injected into the reaction

(combustion) zone of the gasifier. In another embodiment, the combined concentration of oxygen in all gases supplied to the gasification zone is also in the above stated amount. The particular amount of oxygen as supplied to the reaction zone is desirably sufficient to obtain near or maximum yields of carbon monoxide and hydrogen obtained from the gasification reaction relative to the components in the feedstock composition, considering the amount relative to the feedstock composition, and the amount of feedstock charged, the process conditions, and the gasifier design.

[0294] In embodiments, steam is not supplied to the gasification zone in a slurry fed gasifier. The amount of water in a slurry fed system is typically more than sufficient a co-reactant and heat sink to regulate the gasification temperature. The addition of steam in a slurry fed gasifier will generally unduly withdraw heat from the reaction zone and reduce its efficiency. In one embodiment or in combination with any of the mentioned embodiments, steam is fed to the gasification zone in any type of dry fed gasifier, such as an entrainment flow gasifier, a fluidized bed gasifier, or a fixed or moving bed gasifier. The addition of steam in dry fed gasifiers case is desirable to provide the raw material needed for the production of carbon monoxide.

[0295] Other reducible oxygen-containing gases may be supplied to the reaction zone, for example, carbon dioxide, or simply air. In one embodiment or in combination with any of the mentioned embodiments, no gas stream enriched in carbon dioxide or nitrogen (e.g. greater than the molar quantity found in air, or greater than 2 mole%, or greater than 5 mole%, or greater than 10 mole%, or greater than 40 mole%) is charged into a slurry fed gasifier. Many of these gases serve as carrier gases to propel a dry feed to a gasification zone. Therefore, in another embodiment, one or more of these gases are charged to the gasification zone as a carrier gas for the dry feed of solid fossil fuel and size reduced textiles. Due to the pressure within the gasification zone, these carrier gases are compressed to provide the motive force for introduction into the gasification zone. The expenditure of energy and equipment for compressing carrier gases to the feedstock composition is avoided is a slurry feed. Accordingly, in yet another embodiment, the feedstock composition containing at least size reduced textiles and solid fossil fuel flowing to the gasifier, or this feedstock composition as introduced to an injector or charge pipe, or this feedstock composition as introduced into the gasification zone, or a combination of all the above, does not contain gases compressed in equipment for gas compression. Alternatively, or in addition, other than the oxygen rich stream described above, no gas compressed in equipment for gas compression is fed to the gasification zone or even to the gasifier. It is noteworthy that high pressure charge pumps that process the slurry feed for introduction into the gasification zone are not considered gas compressing equipment.

[0296] In embodiments, no gas stream containing more than 0.03 mole%, or more than 0.02 mole%, or more than 0.01 mole% carbon dioxide is charged to the gasifier or gasification zone. In another embodiment, a gas stream containing more than 77 mole%, or more than 80 mole% nitrogen is charged to the gasifier or gasification zone. In another embodiment, no gas stream containing more than 77 mole%, or more than 70 mole%, or more than 50 mole%, or more than 30 mole%, or more than 10 mole%, or more than 5 mole%, or more than 3 mole% nitrogen is charged to the gasifier or gasification zone. In another embodiment, steam is charged into the gasification zone or to the gasifier. In yet another embodiment, a gaseous hydrogen stream (e.g. one containing more than 0.1 mole% hydrogen, or more than 0.5 mole%, or more than 1 mole%, or more than 5 mole%) is not charged to the gasifier or to the gasification zone. In another embodiment, a stream of methane gas (e.g. one containing more than 0.1 mole% methane, or more than 0.5 mole%, or more than 1 mole%, or more than 5 mole% methane) is not charged to the gasifier or to the gasification zone. In another embodiment, the only gaseous stream introduced to the gasification zone is an oxygen rich gas stream as described above.

[0297] In embodiments, the gasifier can be fed with two or more separate streams to the gasification zone. For example, one feedstock composition can contain natural gas (methane) in a concentration of at least 50 mole% and a second feedstock composition can contain size reduced textiles as a dry feed or as a slurry or dispersion in fuel liquids other than water or in liquids containing water or containing more than 50 wt.% water based on the weight of the water. In a natural gas fed gasifier, the amount of methane fed to the gasifier is at least 50 mole%, or at least 70 mole% or at least 80 mole% or at least 90 mole% based on the moles of all gases fed to the gasifier, or based on the moles of all feedstock fuel and reactants fed to the gasifier, or even based on the moles of all fuel fed to the gasifier. Suitable liquids as fuel include those mentioned above that are liquid at 25°C and 1 atm.

[0298] The gasification process desirably employed is a partial oxidation gasification reaction. To enhance the production of hydrogen and carbon monoxide, the oxidation process involves partial, rather than complete, oxidization of the fossil fuel and size reduced textiles and therefore is desirably operated in an oxygen-lean environment, relative to the amount needed to completely oxidize 100% of the carbon and hydrogen bonds. This is in contrast to a combustion reaction which would employ a large

stoichiometric excess of oxygen over that needed to make carbon monoxide, leading to the production primarily of carbon dioxide and water. In the particle oxidation gasification process, the total oxygen requirements for the gasifier is desirably at least 5%, or at least 10%, or at least 15%, or at least 20%, in excess of the amount theoretically required to convert the carbon content of the solid fuel and size reduced textiles to carbon monoxide. In general, satisfactory operation may be obtained with a total oxygen supply of 10 to 80 percent in excess of the theoretical requirements for carbon monoxide production. An example of a suitable amount of oxygen per pound of carbon is in the range of 0.4 to about 3.0-pound free oxygen per pound of carbon, or from 0.6 to 2.5, or from 0.9 to 2.5, or from 1 to 2.5, or from 1.1 to 2.5, or from 1.2 to 2.5 pounds of free oxygen per pound of carbon.

[0299] Mixing of the feedstock composition and the oxidant is desirably accomplished entirely within the reaction zone by introducing the separate streams of feedstock and oxidant so that they impinge upon each other within the reaction zone. Desirably, the oxidant stream is introduced into the reaction zone of the gasifier at high velocity both exceed the rate of flame propagation and to improve mixing with the feedstock composition. The oxidant is desirably injected into the gasification zone in the range of 25 to 500 feet per second, or 50 to 400 ft/s, or 100 to 400 ft/s. These values would be the velocity of the gaseous oxidizing stream at the injector-gasification zone interface, or the injector tip velocity.

[0300] One method for increasing the velocity of the oxidant feed to the gasification zone is by reducing the diameter of the oxidant annulus near the tip of the injector or injector. Near the tip of the injector the annular passage converges inwardly in the shape of a hollow cone as shown in Figures 3 and 4. The oxidizing gas is thereby accelerated and discharged from the injector as a high velocity conical stream having an apex angle in the desirably range of about 30° to 45°. The streams from the injector converge at a point located about 0-6 inches beyond the injector face. The high velocity stream of oxidizing gas hits the relatively low velocity feedstock stream, atomizing it and forming a fine mist comprising minute particles of water and particulate solid fossil fuel highly dispersed in the oxidizing gas. The particles of solid carboniferous matter impinge against one another and are fragmented further.

[0301] The velocity of the fuel feedstock is determined by the desired throughput of size reduced textile derived syngas generation. Suitable examples of feedstock velocity introduced into gasification zone prior to contact with the oxidizing agent is in the range of 5 to 50 feet per second.

[0302] The feedstock composition and the oxidant can optionally be preheated to a temperature above about 200°C, or at least 300°C, or at least 400°C. Advantageously the gasification process does not require preheating the feedstock composition to efficiently gasify the fuel, and a pre-heat treatment step would result in lowering the energy efficiency of the process. Desirably, the feedstock composition, and optionally the oxidant, are not preheated prior to their introduction into the gasifier. A preheat treatment step would be contacting the feedstock composition or oxidant with equipment that raises the temperature of the feedstock composition sufficiently such that the temperature of the feedstock composition or oxidant stream is above 200°C, or above 190°C, or above 170°C, or above 150°C, or above 130°C, or above 1 10°C, or above 100°C, or above 98°C, or above 90°C, or above 80°C, or above 70°C, or above 60°C, immediately prior to introduction into an injector on the gasifier. For example, while coal can be dried with hot air above 200°C, this step would not be considered a preheat of the feedstock composition if the feedstock composition is below 200°C upon its introduction into the injector.

[0303] In another embodiment, no thermal energy (other than incidental heat from processing equipment such as mills, grinders or pumps) is applied to the feedstock composition containing both size reduced textiles and the solid fossil fuel, or to the oxidant stream, at any point prior to its introduction into the injector, or gasifier, or gasification zone (other than the temperature increase experienced in an injector) that would increase the temperature of the stream by more than 180°C, or more than 170°C, or more than 160°C, or more than 150°C, or more than 140°C, or more than 130°C, or more than 120°C, or more than 110°C, or more than 100°C, or more than 90°C, or more than 80°C, or more than 70°C, or more than 60°C, or more than 50°C, or more than 40°C, or more than 30°C.

[0304] The process employs a gasification process, which is distinct from an incineration process that generates primarily carbon dioxide and water, or a pyrolysis process which is a thermal process that degrades a fuel source in the absence of air or oxygen and generates primarily a liquid, or plasma processes in that gasification does not employ a plasma arc.

[0305] In one embodiment, the type of gasification technology employed is a partial oxidation entrained flow gasifier that generates size reduced textile derived syngas. This technology is distinct from fixed bed (or moving bed) gasifiers and from fluidized bed gasifiers. In fixed bed (or moving bed gasifiers), the feedstock stream moves in a countercurrent flow with the oxidant gas, and the oxidant gas typically employed is air. The feedstock stream falls into the gasification chamber, accumulates, and forms a bed of feedstock. Air (or alternatively oxygen) flows from the bottom of the gasifier up through the bed of feedstock material continuously while fresh feedstock continuously falls down from the top by gravity to refresh the bed as it is being combusted. The combustion temperatures are typically below the fusion temperature of the ash and are non-slagging. Whether the fixed bed operated in countercurrent flow or in some instances in co-current flow, the fixed bed reaction process generates high amount of tars, oils, and methane produced by pyrolysis of the feedstock in the bed, thereby both contaminating the size reduced textile derived syngas produced and the gasifier. The contaminated size reduced textile derived syngas requires significant effort and cost to remove tarry residues that would condense once the size reduced textile derived syngas is cooled, and because of this, such size reduced textile derived syngas streams are generally not used to make chemicals and are instead used in direct heating applications, or as liquid fuels. Downdraft fixed or moving bed gasifiers produce less or no tar. Fixed or moving bed gasifiers already equipped or built to be equipped with tar removal processes are suitable to accept a feed of the size reduced textiles.

[0306] In a fluidized bed, the feedstock material in the gasification zone is fluidized by action of the oxidant flowing through the bed at a high enough velocity to fluidize the particles in the bed. In a fluidized bed, the

homogeneous reaction temperatures and low reaction temperatures in the gasification zone also promotes the production of high amounts of unreacted feedstock material and low carbon conversion, and operating temperatures in the fluidized bed are typically between 800-1000°C. Further, in a fluidized bed, it is important to operate below slagging conditions to maintain the fluidization of the feedstock particles which would otherwise stick to the slag and agglomerate. By employing an entrained flow gasification, these deficiencies present with fixed (or moving bed) and fluidized bed gasifiers that are typically used to process waste materials is overcome.

[0307] In embodiments, the feedstock stream is introduced at the top 1 /8 section of the gasifier, desirably at the top 1 /12 of the gasifier height defined by the gasifier shell (not including the injector height protruding from the top of the shell or pipes protruding from the bottom of the shell). The feedstock composition is desirably not introduced into a side wall of the gasifier. In another embodiment, the feedstock composition is not a tangential feed injector.

[0308] In another embodiment, oxidant is introduced at the top 1/8 section of the gasifier, desirably at the top 1/12 of the gasifier height defined by the gasifier shell. The oxidant is desirably not introduced into the side wall of the gasifier or bottom of the flow gasifier. In another embodiment, both the feedstock composition and oxidant are introduced at the top 1/8 section of the gasifier, desirably at the top 1/12 of the gasifier height defined by the gasifier shell. Desirably, the oxidant and feedstock composition are fed co-currently to ensure good mixing. In this regard, a co-current feed means that the axis of the feedstock and oxidant streams are substantially parallel (e.g. not more than a 25° deviation, or not more than a 20°, or not more than a 15°, or not more than a 10°, or not more than a 8°, or not more than a 6°, or not more than a 4°, or not more than a 2°, or not more than a 1 ° deviation from each other) and in the same direction.

[0309] The feedstock and oxidant streams are desirably introduced into the gasification zone through one or more injector nozzles. Desirably, the gasifier is equipped with at least one of the injector nozzles in which through that injector nozzle both a feedstock stream and an oxidant stream are introduced into the gasification zone.

[0310] While the feedstock stream can be a dry feed or a slurry feed, the feedstock stream is desirably a slurry.

[0311] The syngas produced in the gasification process is desirably used at least in part for making chemicals. Many synthetic processes for making chemicals are at high pressure, and to avoid energy input into pressurizing the size reduced textile derived syngas stream, desirably the gasifier is also run at high pressure, particularly when the syngas stream is directly or indirectly in gaseous communication with a vessel in which a chemical is synthesized. Dry feeds to a gasifier operating at high pressure are specially treated to ensure that the feed can be effectively blown and injected into the high-pressure gasification zone. Some techniques include entraining a flow of nitrogen at high pressure and velocity, which tends to dilute the syngas stream and reduce the concentration of desirably components such as carbon monoxide and hydrogen. Other carrier or motive gases include carbon monoxide, but like nitrogen, these gases are compressed before feeding into or compressed with the solid fossil fuels, adding to the energy requirements and capital cost of feed lock hoppers and/or compressing equipment. To deal with these issues, many dry feed gasifiers will operate at lower pressures, which for the mere production of electricity is sufficient, but is undesirable for gasifiers producing a syngas stream for making chemicals. With a slurry feed, a motive gas is not necessary and can readily be fed to a high-pressure gasifier that produces syngas as high pressure, which is desirable for making chemicals. In one embodiment or in combination with any of the mentioned embodiments, the feedstock stream is not processed through a lock hopper prior to entering an injector or entering the gasification zone. In another embodiment, the feedstock composition containing size reduced textiles and solid fossil fuel is not pressurized in a lock hopper prior to feeding to the injector or gasification zone.

[0312] Desirably, the gasifier is non-catalytic, meaning that gasifier does not contain a catalyst bed, and desirably the gasification process is non- catalytic, meaning that a catalyst is not introduced into the gasification zone as a discrete unbound catalyst (as opposed to captive metals in the size reduced textiles or solid fossil fuel that can incidentally have catalytic activity). The gasification process in the reaction zone is desirably conducted in the absence of added catalysts and contains no catalyst bed. The gasification process is also desirably a slagging gasification process; that is, operated under slagging conditions (well above the fusion temperature of ash) such that a molten slag is formed in the gasification zone and runs along and down the refractory walls. [0313] In another embodiment, the gasifier is not designed to contain a pyrolysis zone. Desirably, the gasifier is not designed to contain a

combustion zone. Most preferably, the gasifier is designed to not contain, or does not contain, either a combustion zone or a pyrolysis zone. The pyrolysis zone incompletely consumes the fuel source leading to potentially high amounts of ash, char, and tarry products. A combustion zone, while absent in tars, produces high amounts of C02 and lower amounts of the more desirably carbon monoxide and hydrogen. Desirably, the gasifier is a single stage reactor, meaning that there is only one zone for conversion of the carbon in the feedstock to size reduced textile derived syngas within the gasifier shell.

[0314] The gasification zone is void or empty space defined by walls in which oxidation reactions occur and allow gases to form within the space. Desirably, gasification zone does not have a bath of molten material or molten material that accumulates at the bottom of the gasification zone to form a bath. The gasification zone is desirably not enclosed on the bottom but rather is in gaseous communication with other zones below the gasification zone. Slag, while molten, does not accumulate at the bottom of the gasification zone but rather runs down the sides of the refractory and into a zone below the gasification zone, such as a quench zone to solidify the slag.

[0315] The flow of hot raw size reduced textile derived syngas in the gasifier is desirably vertically downward, or a down-flow gasifier. Desirably, the flow of syngas generated in the gasifier is downward from the highest point of injecting the feedstock composition, desirably from the point of all feedstock stream locations. In another embodiment, the location for withdrawing the size reduced textile derived syngas stream from the gasifier is lower that at least one location for introducing the feedstock stream, desirably lower than all locations for introducing a feedstock stream.

[0316] The gasifier can contain refractory lining in the gasification zone. While a steam generating membrane or jacket between the gasifier wall and the surfaces facing the gasification zone can be employed, desirably the gasifier does not contain a membrane wall, or a steam generating membrane, or a steam jacket in the gasification zone or between inner surfaces facing the gasification zone and the gasifier shell walls as this removes heat from the gasification zone. Desirably, the gasification zone is lined with refractory, and optionally there is no air or steam or water jacket between the refractory lining the gasification zone (or optionally in any reaction zone such as combustion or pyrolysis) and the outer shell of the gasifier.

[0317] The gasification process is desirably a continuous process meaning that the gasifier operates in a continuous mode. The inclusion of pre-size reduced textiles into the feedstock composition can be intermittent or continuous provided that a continuous feed of fossil fuel is fed to the gasifier since the gasification process in the gasifier is in a continuous mode. By a continuous mode for gasifier operation is meant that the gasification process is continuous for at least 1 month, or at least 6 months, or at least 1 year. Desirably, the inclusion of size reduced textiles in the feedstock composition is continuous for at least 1 day, or at least 3 days, or at least 14 days, or at least 1 month, or at least 6 months, or at least 1 year. A process is deemed continuous despite shut-downs due to maintenance or repair.

[0318] The feedstock can be fed into the gasification zone through one or more injectors. In one embodiment or in combination with any of the mentioned embodiments, the gasifier contains only one injector. In another embodiment, the gasifier contains only one location for introducing feedstock. Typically, the injector nozzle serving the gasification chamber is configured to have the feedstock stream concentrically surround the oxidizer gas stream along the axial core of the nozzle. Optionally, the oxidizer gas stream can also surround the feedstock stream annulus as a larger, substantially concentric annulus. Radially surrounding an outer wall of the outer oxidizer gas channel can be an annular cooling water jacket terminated with a substantially flat end-face heat sink aligned in a plane substantially

perpendicular to the nozzle discharge axis. Cool water is conducted from outside the combustion chamber into direct contact with the backside of the heat sink end-face for conductive heat extraction. [0319] The reaction between the hydrocarbon and oxygen should take place entirely outside the injector proper to prevent localized concentration of combustible mixtures at or near the surfaces of the injector elements.

[0320] In embodiments, the gasification zone, and optionally all reaction zones in the gasifier are operated at a temperature in the range of at least 1000° C, or at least 1100°C, or at least 1200°C, or at least 1250°C, or at least 1300°C, and up to about 2500°C, or up to 2000° C., or up to 1800°C, or up to 1600°C, each of which are well above the fusion temperature of ash, and are desirably operated to form a molten flow of slag in the reaction zone. In one embodiment or in combination with any of the mentioned embodiments, the reaction temperature is desirably autogenous. Advantageously, the gasifier operating in steady state mode is at an autogenous temperature and does not require application of external energy sources to heat the gasification zone. In a fixed bed, moving bed, or fluidized bed gasifier, the gasification zone is generally below 1000°C, or not above 950°C, or not higher than 800°C.

[0321] In one embodiment or in combination with any of the mentioned embodiments, the gasifier does not contain a zone within the gasifier shell to dry feedstock such as the coal, pet-coke, or size reduced textiles prior to gasification. The increase in temperature within the injector is not considered a zone for drying.

[0322] Desirably, the gasification zone is not under negative pressure during operations, but rather is under positive pressure during operation. The gasification zone is desirably not equipped with any aspirator or other device to create a negative pressure under steady state operation.

[0323] The gasifier can be operated at a pressure within the gasification zone (or combustion chamber) of at least 200 psig (1.38 MPa), or at least 300 psig (2.06 MPa), or at least 350 psig (2.41 MPa), and desirably at least 400 psig (2.76 MPa), or at least 420 psig (2.89 MPa), or at least 450 psig (3.10

MPa), or at least 475 psig (3.27 MPa), or at least 500 psig (3.44 MPa), or at least 550 psig (3.79 MPa), or at least 600 psig (4.13 MPa), or at least 650 psig (4.48 MPa), or at least 700 psig (4.82 MPa), or at least 750 psig (5.17 MPa), or at least 800 psig (5.51 MPa), or at least 900 psig (6.2 MPa), or at least 1000 psig (6.89 MPa), or at least 1 100 psig (7.58 MPa), or at least 1200 psig (8.2 MPa). The particular operating pressure on the high end is regulated with a variety of considerations, including operating efficiency, the operating pressures needed in chemical synthesis gasifiers particularly with integrated plants, and process chemistry. Suitable operating pressures in the gasification zone on the high end need not exceed 1300 psig (8.96 MPa), or need not exceed 1250 psig (8.61 MPa), or need not exceed 1200 psig (8.27 MPa), or need not exceed 1 150 psig (7.92 MPa), or need not exceed 1 100 psig (7.58 MPa), or need not exceed 1050 psig (7.23 MPa), or need not exceed 1000 psig (6.89 MPa), or need not exceed 900 psig (6.2 MPa), or need not exceed 800 psig (5.51 MPa), or need not exceed 750 psig (5.17 MPa). Examples of suitable desirably ranges include 400 to 1000, or 425 to 900, or 450 to 900, or 475 to 900, or 500 to 900, or 550 to 900, or 600 to 900, or 650 to 900, or 400 to 800, or 425 to 800, or 450 to 800, or 475 to 800, or 500 to 800, or 550 to 800, or 600 to 800, or 650 to 800, or 400 to 750, or 425 to 750, or 450 to 750, or 475 to 750, or 500 to 750, or 550 to 750, each in psig.

[0324] Desirably, the average residence time of gases in the gasifier reactor are very short to increase throughput. Since the gasifier is operated at high temperature and pressure, substantially complete conversion of the feedstock to gases can occur in a very short time frame. The average residence time of the gases in the gasifier can be as short as less than 30 seconds, or not more than 25 seconds, or not more than 20 seconds, or not more than 15 seconds, or not more than 10 seconds, or not more than 7 seconds. Desirably, the average residence time of gases in all zones designed for conversion of feedstock material to gases is also quite short, e.g. less than 25 seconds, or not more than 15 seconds, or not more than 10 seconds, or not more than 7 seconds, or not more than 4 seconds. In these time frames, at least 85 wt.%, or at least or more than 90 wt.%, or at least 92 wt.%, or at least 94 wt.% of the solids in the feedstock can be converted to gases (substances which remain as a gas if the gas stream were cooled to 25°C and 1 atm) and liquid (substances which are in liquid state if the gas stream is cooled to 25°C and 1 atm such as water), or more than 93 wt.%, or more than 95 wt.%, or more than 96 wt.%, or more than 97 wt.%, or more than 98 wt.%, or more than 99 wt.%, or more than 99.5 wt.%.

[0325] A portion of ash and/or char in the gasifier can be entrained in the hot raw size reduced textile derived syngas stream leaving the gasification reaction zone. Ash particles in the raw size reduced textile derived syngas stream within the gasifier are particles which have not reached the melting temperature of the mineral matter in the solid fuel. Slag is substantially molten ash or molten ash which has solidified into glassy particles and remains within the gasifier. Slag is molten until quenched and then form beads of fused mineral matter. Char are porous particles that are

devolatilized and partially combusted (incompletely converted) fuel particles. The particulate matter gathered in the bottom part of the gasifier, or the quench zone, are predominately slag (e.g. above 80 wt.% slag) and the remainder is char and ash. Desirably, only trace amounts of tar or no tar is present in the gasifier, or in the quench zone, or in the gasification zone, or present in the hot raw size reduced textile derived syngas within the gasifier, or present in the raw size reduced textile derived syngas discharged from the gasifier (which can be determined by the amount of tar condensing from the size reduced textile derived syngas stream when cooled to a temperature below 50°C.). Trace amounts are less than 0.1 wt.% (or less than 0.05 wt.% or less than 0.01 wt.%) of solids present in the gasifier, or less than 0.05 volume%, or not more than 0.01 vol%, or not more than 0.005 vol%, or not more than 0.001 volume%, or not more than 0.0005 vol%, or not more than 0.0001 vol% in the raw size reduced textile derived syngas stream discharged from the gasifier.

[0326] In another embodiment, the process does not increase the amount of tar to a substantial extent relative to the same process except replacing the size reduced textiles with the same amount and type of solid fossil fuel used in the feedstock composition containing the size reduced textiles.

[0327] The quantity of tar generated in the process with the feedstock containing the size reduced textiles are less than 10% higher, or less than 5% higher, or less than 3 % higher, or less than 2% higher, or not higher at all, than the amount of tar generated with the same feedstock replacing the size reduced textiles with the same solid fossil fuel under the same conditions.

[0328] To avoid fouling downstream equipment from the gasifier

(scrubbers, CO/H2 shift reactors, acid gas removal, chemical synthesis), and the piping in-between, the size reduced textile derived syngas stream should have low or no tar content. The size reduced textile derived syngas stream as discharged from the gasifier desirably contains no or less than 4 wt.%, or less than 3 wt.%, or not more than 2 wt.%, or not more than 1 wt.%, or not more than 0.5 wt.%, or not more than 0.2 wt.%, or not more than 0.1 wt.%, or not more than 0.08 wt.%, or not more than 0.05 wt.%, or not more than 0.02 wt.%, or not more than 0.01 wt.%, or nor more than 0.005 wt.% tar, based on the weight of all condensable solids in the size reduced textile derived syngas stream. For purposes of measurement, condensable solids are those compounds and elements that condense at a temperature of 15°C/1 atm.

[0329] In another embodiment, the tar present, if at all, in the size reduced textile derived syngas stream discharged from the gasifier is less than 10 g/m3 of the size reduced textile derived syngas discharged, or not more than 9 g/m3, or not more than 8 g/m3, or not more than 7 g/m3,or not more than 6 g/m3, or not more than 5 g/m3, or not more than 4 g/m3, or not more than 3 g/m3, or not more than 2 g/m3, and desirably not more than 1 g/m3, or not more than 0.8 g/m3, or not more than 0.75 g/m3, or not more than 0.7 g/m3, or not more than 0.6 g/m3, or not more than 0.55g/m3, or not more than 0.45 g/m3, or not more than 0.4 g/m3, or not more than 0.3 g/m3, or not more than 0.2 g/m3, or not more than 0.1 g/m3, or not more than 0.05 g/m3, or not more than 0.01 g/m3, or not more than 0.005 g/m3, or not more than 0.001 g/m3, or not more than 0.0005 g/m3, in each case Normal (15°C/1 atm). For purposes of measurement, the tars are those tars that would condense at a temperature of 15°C/1 atm, and includes primary, secondary and tertiary tars, and are aromatic organic compounds and other than ash, char, soot, or dust.

Examples of tar products include naphthalenes, cresols, xylenols,

anthracenes, phenanthrenes, phenols, benzene, toluene, pyridine, catechols, biphenyls, benzofurans, benzaldehydes, acenaphthylenes, fluorenes, naphthofurans, benzanthracenes, pyrenes, acephenanthrylenes,

benzopyrenes, and other high molecular weight aromatic polynuclear compounds. The tar content can be determined by GC-MSD.

[0330] In another embodiment, the tar yield of the gasifier (combination of tar in size reduced textile derived syngas and tar in reactor bottoms and in or on the ash, char, and slag) is not more than 4 wt.%, or not more than 3 wt.%, or not more than 2.5 wt.%, or not more than 2.0 wt.%, or not more than 1.8 wt.%, or not more than 1.5 wt.%, or not more than 1 .25 wt.%, or not more than 1 wt.%, or not more than 0.9 wt.%, or not more than 0.8 wt.%, or not more than 0.7 wt.%, or not more than 0.5 wt.%, or not more than 0.3 wt.%, or not more than 0.2 wt.%, or not more than 0.1 wt.%, or not more than 0.05 wt.%, or not more than 0.01 wt.%, or not more than 0.005 wt.%, or not more than 0.001 wt.%, or not more than 0.0005 wt.%, or not more than 0.0001 wt.%, based on the weight of solids in the feedstock composition fed to the gasification zone.

[0331] The amount of char (or incompletely converted carbon in the feedstock) generated by conversion of the carbon sources in the feedstock composition is not more than 15 wt.%, or not more than 12 wt.%, or not more than 10 wt.%, or not more than 8 wt.%, or not more than 5 wt.%, or not more than 4.5 wt.%, or not more than 4 wt.%, or not more than 3.5 wt.%, or not more than 3 wt.%, or not more than 2.8 wt.%, or not more than 2.5 wt.%, or not more than 2.3 wt.%, or not more than 4.5 wt.%, or not more than 4.5 wt.%, or not more than 4.5 wt.%.

[0332] In the process, char can be recycled back to the feedstock composition to the gasifier containing the size reduced textiles. In another embodiment, the efficiencies and features can be obtained without recycling char back to the gasification zone.

[0333] The total amount of char (or incompletely converted carbon in the feedstock) and slag (if any) generated in the gasifier or by the process is desirably not more than 20 wt.%, or not more than 17 wt.%, or not more than 15 wt.%, or not more than 13 wt.%, or not more than 10 wt.%, or not more than 9 wt.%, or not more than 8.9 wt.%, or not more than 8.5 wt.%, or not more than 8.3 wt.%, or not more than 8 wt.%, or not more than 7.9 wt.%, or not more than 7.5 wt.%, or not more than 7.3 wt.%, or not more than 7 wt.%, or not more than 6.9 wt.%, or not more than 6.5 wt.%, or not more than 6.3 wt.%, or not more than 6 wt.%, or not more than 5.9 wt.%, or not more than 5.5 wt.%, in each case based on the weight of the solids in the feedstock composition. In another embodiment, the same values apply with respect to the total amount of ash, slag, and char generated in the gasifier or by the process, based on the weight of the solids in the feedstock composition. In another embodiment, the same values apply with respect to the total amount of ash, slag, char and tar generated in the gasifier or by the process, based on the weight of the solids in the feedstock composition.

[0334] The raw syngas stream flows from the gasification zone to a quench zone at the bottom of the gasifier where the slag and raw syngas stream are cooled, generally to a temperature below 550°C, or below 500°C, or below 450°C. The quench zone contains water in a liquid state. The hot syngas from the gasification zone may be cooled by directly contacting the syngas stream with liquid water. The syngas stream can be bubbled through the pool of liquid water, or merely contact the surface of the water pool. In addition, the hot syngas stream may be cooled in a water jacketed chamber having a height that above the top surface of the water pool to allow the hot syngas to both contact the water pool and be cooled in the water jacketed chamber. Molten slag is solidified by the quench water and most of the ash, slag and char are transferred to the water in the quench tank. The partially cooled gas stream, having passed through the water in the quench zone, may be then discharged from the gasifier as a raw syngas stream and passed through a water scrubbing operation to remove any remaining entrained particulate matter.

[0335] The pressure in the quench zone is substantially the same as the pressure in the gasification zone located above the water level in the gasifier, and a portion of the quench water and solids at the bottom of the quench tank is removed by way of a lock hopper system. A stream of quench water carrying fine particles exits the gasifier quench zone in response to a liquid level controller and can be directed to a settler. The solids and water from the lock hopper may then flow into a water sump or settler where optionally the coarse particulate solids may be removed by screens or filter thereby producing a dispersion of fine particulate solids.

[0336] The raw gas stream discharged from the gasification vessel includes such gasses as hydrogen, carbon monoxide, carbon dioxide and can include other gases such as methane, hydrogen sulfide and nitrogen depending on the fuel source and reaction conditions. Carbon dioxide in the raw size reduced textile derived syngas stream discharged from the gasification vessel is desirably present in an amount of less than 20 mole%, or less than 18 mole%, or less than 15 mole%, or less than 13 mole%, or not more than 1 1 mole%, based on all moles of gases in the stream. Some nitrogen and argon can be present in the raw size reduced textile derived syngas stream depending upon the purity of the fuel and oxygen supplied to the process.

[0337] In one embodiment or in combination with any of the mentioned embodiments, the raw size reduced textile derived syngas stream (the stream discharged from the gasifier and before any further treatment by way of scrubbing, shift, or acid gas removal) can have the following composition in mole % on a dry basis and based on the moles of all gases (elements or compounds in gaseous state at 25°C and 1 atm) in the raw size reduced textile derived syngas stream: a. H2: 15 to 60, or 18 to 50, or 18 to 45, or 18 to 40, or 23 to 40, or 25 to 40, or 23 to 38, or 29 to 40, or 31 to 40

b. CO: 20 to 75, or 20 to 65, or 30 to 70, or 35 to 68, or 40 to 68, or 40 to 60, or 35 to 55, or 40 to 52

[0338] The gas components can be determined by FID-GC and TCD-GC or any other method recognized for analyzing the components of a gas stream.

[0339] The molar hydrogen/carbon monoxide ratio is desirably at least 0.65, or at least 0.68, or at least 0.7, or at least 0.73, or at least 0.75, or at least 0.78, or at least 0.8, or at least 0.85, or at least 0.88, or at least 0.9, or at least 0.93, or at least 0.95, or at least 0.98, or at least 1.

[0340] The total amount of hydrogen and carbon monoxide relative to the total amount of size reduced textile derived syngas discharged from the gasifier on a dry basis is high, on the order of greater than 70 mole%, or at least 73 mole%, or at least 75 mole%, or at least 77 mole%, or at least 79 mole%, or at least 80 mole%, based on the size reduced textile derived syngas discharged.

[0341] In another embodiment, the dry size reduced textile derived syngas production expressed as gas volume discharged from the gasifier per kg of solid fuel (e.g. size reduced textiles and coal) charged to all locations on the gasifier is at least 1.7, or at least 1.75, or at least 1.8, or at least 1.85, or at least 1.87, or at least 1.9, or at least 1.95, or at least 1.97, or at least 2.0, in each case as N m3 gas/kg solids fed.

[0342] The carbon conversion efficiency in one pass is good and can be calculated according to the following formula:

100

[0343] The carbon conversion efficiency in the process in one pass can be at least 70%, or at least 73%, or at least 75%, or at least 77%, or at least 80%, or at least 82%, or at least 85%, or at least 88%, or at least 90%, or at least 93%.

[0344] In another embodiment, the raw size reduced textile derived syngas stream contains particulate solids in an amount of greater than 0 wt.% up to 30 wt. %, or greater than 0 wt.% up to 10 wt.%, or greater than 0 wt.% up to 5 wt.%, or greater than 0 wt.% up to 1 wt.%, or greater than 0 wt.% up to 0.5 wt.%, or greater than 0 wt.% up to 0.3 wt.%, or greater than 0 wt.% up to 0.2 wt.%, or greater than 0 wt.% up to 0.1 wt.%, or greater than 0 wt.% up to 0.05 wt.%, each based on the weight of solids in the feedstock composition. The amount of particulate solids in this case is determined by cooling the size reduced textile derived syngas stream to a temperature of below 200°C, such as would occur in a scrubbing operation.

[0345] The cold gas efficiency of the process using the size reduced textiles/solid fossil fuel as a percent can be calculated as:

[0346] The cold gas efficiency is at least 60%, or at least 65%, or at least

66%, or at least 67%, or at least 68%, or at least 69%, or desirably at least

70%, or at least 71 %, or at least 72%, or at least 73%, or at least 74%, or at least 75%, or at least 76%, or at least 77%, or at least 78%, or at least 79%. [0347] In embodiments, hydrogen and carbon monoxide from the raw size reduced textile derived syngas stream discharged from the gasifier or from a scrubbed or purified size reduced textile derived syngas stream are not recycled or recirculated back to a gasification zone in a gasifier. Desirably, carbon dioxide from the raw size reduced textile derived syngas stream discharged from the gasifier or from a scrubbed or purified size reduced textile derived syngas stream is not recycled or recirculated back to a gasification zone in a gasifier. Desirably, no portion of the size reduced textile derived syngas stream discharged from the gasifier or from a scrubbed or purified size reduced textile derived syngas stream is recycled or recirculated back to a gasification zone in a gasifier. In another embodiment, no portion of the size reduced textile derived syngas discharged from the gasifier is used to heat the gasifier. Desirably, no portion of the size reduced textile derived syngas made in the gasifier is burned to dry the solid fossil fuel.

[0348] The feedstock stream is gasified with the oxidizer such as oxygen desirably in an entrained flow reaction zone under conditions sufficient to generate a molten slag and ash. The molten slag and ash are separated from the syngas and quench cooled and solidified. In a partial oxidation reactor, the coal/size reduced textiles/water mixture is injected with oxygen and the coal/rubber will react with oxygen to generate a variety of gases, including carbon monoxide and hydrogen (syngas). The molten slag and unreacted carbon/size reduced textiles accumulate into a pool of water in the quench zone at the bottom part of the gasifier to cool and solidify these residues.

[0349] In embodiments, the slag is discharged from the gasifier as a solid. Slag is cooled and solidified within the gasifier in a quench zone within the shell of the gasifier, and is discharged from the gasifier shell as a solid. The same applies to ash and char. These solids discharged from the gasifier are accumulated into a lock hopper which can then be emptied. The lock hopper is generally isolated from the gasifier and the quench zone within the gasifier.

[0350] The process can be practiced on an industrial scale and on a scale sufficient to provide size reduced textile derived syngas as a raw material to make chemicals on an industrial scale. At least 300 tons/day, or at least 500 t/d, or at least 750 t/d, or at least 850 t/d, or at least 1000 t/d, or at least 1250 t/d, and desirably at least 1500 t/d, or at least 1750 t/d, or even at least 2000 t/d of solids can be fed to the gasifier. The gasifier is desirably not designed to be mobile and is fixed to and above the ground, and desirably stationary during operations.

[0351] The size reduced textile derived syngas compositional variability produced by gasifying the feedstock containing the solid fossil fuel and size reduced textiles are quite low over time. In one embodiment or in

combination with any of the mentioned embodiments, the compositional variability of the size reduced textile derived syngas stream is low during a time period when the feedstock composition contains the solid fossil fuel and the size reduced textiles. The compositional variability of the size reduced textile derived syngas stream can be determined by taking at least 6 measurements of the concentration of the relevant gaseous compound in moles in equal time sub-periods across the entire time that the feedstock solids content is consistent and contain size reduced textiles, such entire time not to exceed 12 days. The mean concentration of the gaseous compound is determined over the 6 measurements. The absolute value of the difference between the number farthest away from the mean and the mean number is determined and divided into the mean number x 100 to obtain a percent compositional variability.

[0352] The compositional variability of any one of:

a. CO amount, or

b. H2 amount, or

c. C02 amount, or

d. CH4 amount, or

e. H2S amount, or

f. COS amount, or

g. H2 + CO amount, or its molar ratio in sequence (e.g. H2:CO ratio), or h. H2 + CO + C02 amount, or its molar ratio in sequence, or i. H2 + CO + CH4 amount, or its molar ratio in sequence, or j. H2 + CO + C02 + CH4 amount, or its molar ratio in sequence, or k. H2S + COS amount, or its molar ratio in sequence, or

L. H2 + CO + CO2 + CH4 + H2S + COS,

can be not more than 5%, or not more than 4%, or not more than 3%, or not more than 2%, or not more than 1 %, or not more than 0.5%, or not more than 0.25% during the shorter of a 12-day period or the time that size reduced textiles are present in the feedstock composition.

[0353] In another embodiment, variability of the size reduced textile derived syngas stream generated by all feedstock sources containing fuel (liquid, gas, or solid) at least one of which contains size reduced textiles (“textile case”) is compared to a benchmark variability of the size reduced textile derived syngas stream generated from the same feedstocks without the size reduced textiles and the size reduced textiles amount is replaced by a corresponding amount of the same fuel (“base case”) and processed under the same conditions to obtain a % switching variability, or in other words, the size reduced textile derived syngas variability generated by switching between the two feedstock compositions. The size reduced textile derived syngas variation of the textile case can be less than, or no different than, or if higher can be similar to the size reduced textile derived syngas variation of the base case. The time periods to determine variations is set by the shorter of a 12- day period or the time that size reduced textiles are present in the feedstock composition, and that time period is the same time period used for taking measurements in the solid fossil fuels only case. The measurements for the base case are taken within 1 month before feeding a feedstock containing size reduced textiles to the gasifier or after the expiration of feeding a feedstock containing size reduced textiles to the gasifier. The variations in size reduced textile derived syngas composition made by each of the streams is measured according to the procedures stated above. The size reduced textile derived syngas variability from the textile case is less than, or the same as, or not more than 15%, or not more than 10%, or not more than 5%, or not more than 4%, or not more than 3%, or not more than 2%, or not more than 1 %, or not more than 0.5%, or not more than 0.25% of the size reduced textile derived syngas variability of the base case. This can be calculated as:

where %SV is percent size reduced textile derived syngas switching variability on one or more measured ingredients in the size reduced textile derived syngas composition; and

Vt is the size reduced textile derived syngas compositional variability using feedstock(s) containing size reduced textiles and a second source of fuel together in one stream or in separate feedstock streams; and

Vb is the size reduced textile derived syngas compositional variability using the base case streams (same type and amount of fuel feedstock without the size reduced textiles), where the solids concentration is the same in both cases, the fuel is the same in both cases other than the presence of absence of the size reduced textiles, and the feedstocks are gasified under the same conditions, other than temperature fluctuations which may autogeneously differ as a result of having size reduced textiles in the feedstock, and the variabilities are with respect to any one or more of the size reduced textile derived syngas compounds identified above. In the event that the %SV is negative, then the size reduced textile derived syngas textile case variability is less than the size reduced textile derived syngas base case.

[0354] In another embodiment, the ratio of carbon monoxide/hydrogen generated from one or more streams that contain size reduced textiles and other fuel sources (textile case) is similar to the carbon monoxide/hydrogen ratio generated from the same stream(s) replacing the size reduced textiles content with the same fuel (base case). The carbon monoxide/hydrogen ratio between the textile case and the base case can be within 10%, or within 8%, or within 6%, or within 5%, or within 4%, or within 3%, or within 2%, or within 1.5%, or within 1 %, or within 0.5% of each other. The percentage similarity can be calculated by taking the absolute value of the differences in CO/H2 ratios between the textile case and the base case and dividing that number into the CO/H2 ratio of the base case x 100.

[0355] In another embodiment, the amount of C02 generated from a textile case is similar to the amount of carbon dioxide generated from a base case. The process can be conducted such that the amount of CO2 generated from textile case is no more than 25%, or no more than 20%, or no more than 15%, or no more than 13%, or no more than 10%, or no more than 8%, or no more than 7%, or no more than 6%, or no more than 5%, or no more than 4%, or no more than 3%, or no more than 2%, or no more than 1 %, or no more than 0.75%, or no more than 0.5%, or nor more than 0.25%, or no more than 0.15%, or no more than 0.1 % greater than the amount of carbon dioxide generated from a base case. The percentage similarity can be calculated by subtracting the amount of CO2 generated in a syngas stream using the textile case from the amount of CO2 generated in a syngas stream using the base case, and dividing that number by the C02 generated in a size reduced textile derived syngas stream using the base case.

[0356] In another embodiment, there is provided a continuous process for feeding a gasifier with a continuous feedstock composition containing solid fossil fuel and intermittently feeding a feedstock composition containing size reduced textiles and solid fossil fuel, while maintaining a negative, zero, or minimal size reduced textile derived syngas compositional switching variability over time frames that includes feedstocks with and without the size reduced textiles using size reduced textile derived syngas produced using feedstocks without the size reduced textiles as the benchmark. For example, switching frequency between feedstocks without the size reduced textiles (base case) and the identical feedstocks except replacing a portion of the fuel with the size reduced textiles (textile case) can be at least 52x/yr, or at least 48x/yr, or at least 36x/yr, or at least 24x/yr, or at least 12x/yr, or at least 6x/yr, or at least 4x/yr, or at least 2x/yr, or at least 1 x/yr, or at least 1 x/2yr, and up to 3x/2yr, without incurring a size reduced textile derived syngas switching variability beyond the percentages express above. One switch is counted as the number of times in a period that the textile case is used.

[0357] To illustrate an example of a slurry fed slagging entrained flow process, reference made to Figure 1. Coal is fed through line 1 into a coal grinding zone 2 wherein it is mixed with a water from stream 3 and ground to the desired particle size. A suitable coal grinding process includes a shearing process. Examples of a suitable apparatus include ball mill, a rod mill, hammer mill, a raymond mill, or an ultrasonic mill; desirably a rod mill. The rod mill is desirably the wet grind type to prepare a slurry. A rod mill contains a number of rods within a cylinder where the rods rotate about a horizontal or near horizontal axis. The coal is ground when it is caught between the rods and cylinder wall by the rolling/rotating action of the rods. The rod mill can be the overflow type, end peripheral discharge, and center peripheral discharge, desirably the overflow type.

[0358] The grinder can also be equipped with a classifier to remove particles above the target maximum particle size. An example of a classifier is a vibrating sieve or a weir spiral classifier.

[0359] The coal grinder zone (which includes at least the grinding equipment, feed mechanisms to the grinder, and any classifiers) is a convenient location for combining size reduced textiles particles through line 4 to the coal. The desired amount of coal and size reduced textiles can be combined onto a weigh belt or separately fed though their dedicated weigh belts that feed the grinding apparatus. The water slurry of ground coal and size reduced textiles are discharged through line 5 and pumped into a storage/charge tank 6 that is desirably agitated to retain a uniform slurry suspension. Alternatively, or in addition to the grinder 2 location, size reduced textiles can be added into the charge/storage tank 6 through line 7, particularly when this tank is agitated. [0360] The feedstock composition is discharged from tank 6 directly or indirectly to the gasifier 9 through line 8 into the injector 10 in which the coal/rubber/water slurry is co-injected with an oxygen-rich gas from line 1 1 into the gasification reaction zone 12 where gasification takes place. The injector 10 may optionally be cooled with a water line 13 feeding a jacket on the injector and discharged through line 14. After start-up and in a steady state, the reaction in the reaction zone 12 takes place spontaneously at an autogenous temperature in the ranges noted above, e.g. 1200°C to 1600°C and at a pressure in the ranges note above, e.g. 10 - 100 atmospheres. The gaseous reaction products of the partial oxidation reaction include carbon monoxide, hydrogen, with lesser amounts of carbon dioxide and hydrogen sulfide. Molten ash, unconverted coal or rubber, and slag may also be present in the reaction zone 12.

[0361] The gasifier 9 is illustrated in more detail in Figure 2, also as shown in US Patent 3,544,291 , the entire disclosure of which is incorporated herein by reference. The gasifier comprises a cylindrical pressure vessel 50 with a refractory lining 75 defining a cylindrical, compact, unpacked reaction zone 54. The mixture of coal, size reduced textiles, water and oxygen is injected through an injector axially into the upper end of reaction zone 54 through inlet passageway 76. Products of reaction are discharged axially from the lower end of reaction zone 54 through an outlet passageway 77 into a slag quench chamber 71. The quench chamber 71 and the reaction zone 54 are within the outer shell 50 of the gasifier and are in continuous gaseous and fluid communication with each other during the combustion and reaction in reaction zone 54. A pool of water 78 is maintained in the lower portion of quench chamber 71 and a water jacket 79 is provided in the upper portion of the quench chamber 71 to protect the pressure vessel shell from becoming overheated by hot gases from the gasification zone 54. Unconverted solid fuel and molten slag and ash from the solid fuel is discharged with the product gas stream through outlet 77 into the quench chamber 71 where the larger particles of solid and any molten ash or slag drops into the pool of water. The partially cooled gas is discharged from the quench chamber 71 through line 58, which optionally is also provided with a refractory lining 75.

[0362] Turning back to Figure 1 , the hot reaction product gas from reaction zone 12 along with the slag formed on the surfaces of refractory facing the reaction zone 12 are discharged into the quench chamber 15 where they are quickly cooled and solidified below the reaction temperature in zone 12 to form solid slag, ash, and unconverted coal which separates from the hot raw size reduced textile derived syngas to form a raw size reduced textile derived syngas stream which is discharged from the gasifier vessel. The process effectuates a separation of ash, slag, and unconverted products from the reaction product gases, and has the advantage over a fixed or moving bed waste gasifier in that within the gasifier vessel, a first step of purification of the gaseous reaction products from the reaction zone 12 has occurred prior to discharging the raw size reduced textile derived syngas stream from the gasification vessel. At the same time that the slag and vaporized unconverted fossil fuel elements are solidified in the quench water in quench zone 15, and part of the quench water is vaporized producing steam which is useful in subsequent operations, for example, for the water-gas shift reaction of the scrubbed raw size reduced textile derived syngas stream in which hydrogen is produced by reaction of carbon monoxide with water vapor in the presence of a suitable catalyst such as an iron oxide-chromic oxide catalyst.

[0363] The temperature of the raw size reduced textile derived syngas stream exiting the gasification vessel through line 16 can be within a range of 150°C to 700°C, or from 175°C to 500°C. Desirably, the temperature of the raw size reduced textile derived syngas discharged from the gasifier is not more than 500°C, or less than 400°C, or not more than 390°C, or not more than 375°C, or not more than 350°C, or not more than 325°C, or not more than 310°C, or not more than 300°C, or not more than 295°C, or not more than 280°C, or not more than 270°C. The temperature of the raw size reduced textile derived syngas exiting the gasification vessel is substantially reduced from the temperature of the reaction product gases within the reaction zone. The temperature reduction between the gasification zone gas temperature (or alternatively all reaction zones if more than one stage is used) and the raw size reduced textile derived syngas temperature discharged from the gasifier vessel can be at least 300°C, or at least 400°C, or at least 450°C, or at least 500°C, or at least 550°C, or at least 600°C, or at least 650°C, or at least 700°C, or at least 800°C, or at least 900°C, or at least 1000°C, or at least 1050°C, or at least 1 100°C.

[0364] As shown in Figure 1 , the raw size reduced textile derived syngas is discharged from the gasifier through line 16 to a suitable scrubber 17 where it is contacted with water from line 18 for the removal of remaining solid particles from the raw syngas stream. Gas scrubber 17 may comprise a venturi scrubber, a plate type scrubber or a packed column, or a combination thereof, in which raw size reduced textile derived syngas stream is intimately contacted with water to effect the removal of solid particles from the raw size reduced textile derived syngas stream. The scrubbed raw syngas stream is discharged through line 19 for further use in other processes, such as acid gas (e.g. sulfur compounds) removal processes to make the resulting purified size reduced textile derived syngas stream suitable for manufacture of chemicals. Suitable process for acid gas removal include the Rectisol™ and Selexol™ acid gas removal processes. Once the sulfur species are removed from the size reduced textile derived syngas stream, elemental sulfur can be recovered and converted to sulfuric acid and other sulfur products that can be commercialized through processes such as the Claus™ process.

[0365] As shown in Figure 1 , the solids-water mixture from gas scrubber 17 is discharged from the scrubber passed through line 20 optionally to line 21 where it is mixed with quench water containing solids drawn from quench zone 15 via line 22 and the mixture passed through pressure reducing valve 23 into settling tank 24. A heat exchanger 25 serves to heat by heat exchange with hot quench water from line 22 the relatively cool make-up and recycle water supplied through line 26 from a suitable source and pumped to lines for quenching and/or scrubbing the product gas from the gas generator. [0366] Solids, including unconverted particulate coal, settle by gravity from the water in settling tank 24 and are drawn off through line 27 as a

concentrated slurry of ash, unconverted coal and soot in water. This slurry may be optionally be recycled to grinding zone 2 via line 28. If desired, a portion of the slurry from line 27 may be diverted through line 29 into mix tank 6 to adjust the concentration of solids in the water-coal-rubber slurry feed stream charged to the gasifier. Also, as shown in Figure 2, water and solids from settler tank 66 may be drawn off in line 83 for processing, while water and ash, unconverted coal and soot may be drawn off the settle tank 66 through line 84 and combined with the feedstock of coal, size reduced textiles and water.

[0367] As shown in Figure 1 , gases released in settler 24 may be discharged through line 30 and recovered as potential fuel gases. Clarified water from settler 24 is withdrawn through line 31 and recirculated to the quench water system through line 32. A portion of the water from line 32, after passing through heat exchanger 25, is supplied to the quench zone 15 through line 33 and a further portion of the water is passed through line 18 to gas scrubber 17. Further, water from the quench zone can be withdrawn through line 22 to settler 24 through a control valve 23. The water level can be controlled through a liquid level controller on the gasifier to maintain a substantially constant water level in quench zone.

[0368] Alternatively, or in addition, the quench water through line 33 feeding the quench water zone can supplied from a size reduced textile derived syngas scrubber downstream from the gasifier as shown in Figure 2. The quench water stream optionally also fed to the quench zone may be clarified or may contain from about 0.1 weight % soot to about 1.5 weight % soot based on the weight of the quench water stream feeding the gasifier.

[0369] If desired, high temperature surfactants can be added to the quench water directly into the quench zone/chamber. Examples of such surfactants include any one of the surfactants mentioned above to stabilize the feedstock composition, such as ammonium lignosulfonate or an equivalent surfactant which is thermally stable at temperatures of about 300° F. to about 600° F. Other surfactants include organic phosphates, sulfonates and amine surfactants. The surfactants are used to establish a stable suspension of soot in the water at the bottom of the quench chamber, where the soot

concentration can be at least 1 wt.%, or in the range of about 3.0 weight % to about 15.0 weight %, each based on the weight of the water in the quench chamber. The concentration of active surfactants in the bottom of the quench zone can vary from about 0.01 weight % to about 0.30 weight %.

[0370] Also, as illustrated in Figure 2, an internal water jacket 79 is provided within the pressure vessel shell 50 at the upper portion of the quench zone 71. Water jacket 79 prevents overheating of the pressure vessel shell below the level of refractory 75 surrounding reaction zone 54. Water is introduced into water jacket 79 from line 80 and discharged therefrom through line 81 through valve 82 and can be fed directly or indirectly (through a settler tank 66) to a scrubber 59.

[0371] As shown in Figure 1 , periodically slag and other heavy

incombustible solids settling to the bottom of quench zone 15 are withdrawn as a water-solids slurry through line 34 and valve 35 into lock hopper 36.

Accumulated solid material from lock hopper 36 is discharged through line 37 as controlled by valve 38. In the operation of the lock hopper, valve 35 is opened and valve 38 closed during the filling period in which solid material from quench chamber 15 is transferred to lock hopper 36. Valve 35 is then closed and the lock hopper 36 emptied through line 37 by opening valve 38. From lock hopper 36, solid residue and water are discharged through line 37. The equivalent equipment and lines are shown in Figure 2 as outlet 85, valves 86 and 88, line 89, and lock hopper 87.

[0372] In an alternative embodiment as shown in Figure 1 , fresh water can be charged to the lock hopper 36 to displace the sour water in the lock hopper 36. Cold clean water from line 39 is introduced through valve 40 into the lower part of lock hopper 36. Valve 41 in line 42 is opened to establish communication between line 33 and lock hopper 36. As the cold clean water enters the lower part of lock hopper 36, hot sour water is displaced from the lock hopper and flows through line 42 and line 33 into the quench zone 15 as part of the make-up water for the quench system. After the sour water has been displaced from lock hopper 36 valves 40 and 41 are closed and valve 38 opened to permit discharge of slag and clean water from the lock hopper through line 37.

[0373] In an alternate embodiment, as shown in Figure 1 , stripping gas such as carbon dioxide, or gases produced by the gasifier from which acid gases have been removed by chemical treatment, can be introduced into the lower portion of lock hopper 36 through line 43 after the lock hopper has been charged with slag and sour water from the quench zone 15 and valve 35 closed. Stripping gas under pressure is introduced into the lower portion of lock hopper 36 by opening valve 44 in line 43. At the same time, valve 41 in line 42 is opened allowing gas to pass through lines 42 and 33 into the quench zone 15. The stripping gas from line 43 desorbs sour gases, i.e.

sulfides, cyanides, and other noxious gases, from the water in lock hopper 36. When the desorbed gases are introduced back into the gasifier, they mix with hot product gases and, after passing through the quench zone are discharged through line 16 to gas scrubber 17 as a part of the product gas stream for further purification and utilization.

[0374] An example of the operation of the gasifier and scrubber is illustrated in Figure 2. The coal/size reduced textiles feedstock slurry is fed to the gas generator 50 through injector 51 mounted at the top 52 of the gasifier and is fed with oxygen through line 53 and injected into the gasification zone 54 to generate a raw size reduced textile derived syngas. The raw size reduced textile derived syngas gases discharged from the gasifier is fed to a contactor 55. Water is injected into contactor 55 from line 56 through injectors 56 and 57. Intimate contact between the raw size reduced textile derived syngas from line 58 and water from line 56 is effected desirably by way of a venturi, nozzle, or plate orifice. In contactor 55, the size reduced textile derived syngas stream is accelerated, and water is injected into the accelerated gas stream at the throat of the nozzle, venturi or orifice, from a plurality of injectors 56 and 57.

[0375] The resulting mixture of gas and water formed in contactor 55 is directed into scrubber 59 through a dip leg 60 which extends downwardly into the lower portion of scrubber 59. The gas stream from contactor 55 also carries entrained solid particles of unconsumed fuel or ash. A body of water is maintained in the scrubber 59, the level of which may be controlled in any suitable manner, for example by means of a liquid level controller 61 , shown diagrammatically. The dip leg 60 discharges the mixture of water and gas below the level of water contained in the scrubber 59. By discharging the mixture of gas and water through the open end of dip leg 60 into intimate contact with water, solid particles from the gas stream are trapped in the water.

[0376] Scrubber 59 is suitably in the form of a tower having an optionally packed section 62 above the point of entry of the gas stream from contactor 55. Water from line 63 is introduced into scrubber 59 above the level of the packing material 62. In packed section 62, the gas stream is intimately contacted with water in the presence of suitable packing material, such as ceramic shapes, effecting substantially complete removal of solid particles from the gas stream. Product gas, comprising carbon monoxide and hydrogen and containing water vapor, atmospheric gases, and carbon dioxide, is discharged from the upper end of scrubber 59 through line 64 at a temperature corresponding to the equilibrium vaporization temperature of water at the pressure existing in scrubber 59. Clean size reduced textile derived syngas from line 64 may be further processed, for example, for the production of higher concentrations of hydrogen by water-gas shift reaction and suitable downstream purification to remove sulfur.

[0377] Water from the lower portion of scrubber 59 is passed by pump 65 through line 56 to injectors 56 and 57. Clarified water from settler 66 also may be supplied to line 56 by pump 67 through line 68. Water is withdrawn from scrubber 59 by pump 69 and passed through valve 70 responsive to liquid level control 61 on the scrubber and passed into quench zone 71 via line 72 to control the liquid level in scrubber 59.

[0378] Any heavy solid particles removed from the gas stream in the dip leg 60 settling into water slurry are collected the water bath at the bottom of the scrubber 59 and discharged at the bottom leg 73 at periodic intervals through line 74 as controlled by valve 75.

[0379] Any suitable scrubber design can be used in the process. Other scrubber designs include a tray type contacting tower wherein the gases are counter currently contacted with water. Water is introduced into the scrubber at a point near the top of the tower.

[0380] To illustrate one embodiment of an injector, reference is made to Figure 3, showing a partial cut-away view of a synthesis gas gasifier at the injector location. The gasifier vessel includes a structural shell 90 and an internal refractory liner 91 (or multiple liners) around an enclosed gasification zone 93. Projecting outwardly from the shell wall is an injector mounting neck 94 for supporting an elongated fuel injection injector assembly 95 within the gasifier vessel. The injector assembly 95 is aligned and positioned so that the face 96 of the injector nozzle 97 is substantially flush with the inner surface of the refractory liner 91. An injector mounting flange 96 secures the injector assembly 95 to a mounting neck flange 97 of the gasifier vessel to prevent the injector assembly 95 from becoming ejected during operation. A feed of oxygen flows into a central inner nozzle through conduit 98. The feedstock stream is fed to the injector assembly through line 99 into an annular space around the central oxidant nozzle. A cooling jacket surrounding the injector assembly 95 above the injector mounting flange 96 is fed with cooling water 100 to prevent the injector assembly from overheating. An optional second feed of oxidant flows through line 101 into an annular space around at least a portion of the outer surface of the shell defining the feedstock annulus.

[0381] A more detailed view of the injector is shown in Figure 4. A sectional view of a portion of the injector assembly 80 toward the injector nozzle tip is illustrated. The injector assembly 80 includes an injector nozzle assembly 125 comprising three concentric nozzle shells and an outer cooling water jacket 1 10. The inner nozzle shell 1 1 1 discharges from an axial bore opening 1 12 the oxidizer gas that is delivered along upper assembly axis conduit 98 in Figure 3. Intermediate nozzle shell 1 13 guides the feedstock stream into the gasification zone 93. As a fluidized solid, this size reduced textile/coal slurry is ejected from the annular space 1 14 defined by the inner shell wall 1 11 and the intermediate shell wall 1 13. The outer, oxidizer gas nozzle shell 1 15 surrounds the outer nozzle discharge annulus 1 16. The upper assembly port 101 , as shown in Figure 3, supplies the outer nozzle discharge annulus with an additional stream of oxidizing gas. Centralizing fins

1 17 and 1 18 extend laterally from the outer surface of the inner and

intermediate nozzle shell walls 1 1 1 and 1 13, respectively to keep their respective shells coaxially centered relative to the longitudinal axis of the injector assembly. It will be understood that the structure of the fins 1 17 and

1 18 form discontinuous bands about the inner and intermediate shells and offer small resistance to fluid flow within the respective annular spaces.

[0382] The internal nozzle shell 1 1 1 and intermediate nozzle shell 1 13 can both be axially adjustable relative to the outer nozzle shell 115 for the purpose flow capacity variation. As intermediate nozzle 1 13 is axially displaced from the conically tapered internal surface of outer nozzle 1 15, the outer discharge annulus 1 16 is enlarged to permit a greater oxygen gas flow. Similarly, as the outer tapered surface of the internal nozzle 1 1 1 is axially drawn toward the internally conical surface of the intermediate nozzle 1 13, the feedstock slurry discharge area 1 14 is reduced.

[0383] Surrounding the outer nozzle shell 1 15 is a coolant fluid jacket 1 10 having an annular end closure 1 19. A coolant fluid conduit 120 delivers a coolant, such as water, from the upper assembly supply port 100 in Figure 3 directly to the inside surface of the end closure plate 119. Flow channeling baffles 121 control the path of coolant flow around the outer nozzle shell to assure a substantially uniform heat extraction and to prevent the coolant from channeling and producing localized hot spots. The end closure 1 19 includes a nozzle lip 122 that defines an exit orifice or discharge opening for the feeding of reaction materials into the injection injector assembly.

[0384] The planar end of the cooling jacket 1 19 includes an annular surface 123 which is disposed facing the combustion chamber. Typically, the annular surface 123 of cooling jacket is composed of cobalt base metal alloy materials. Although cobalt is the preferred material of construction for the nozzle assembly 125, other high temperature melting point alloys, such as molybdenum or tantalum may also be used. The heat shield 124 is formed from a high temperature melting point material such as silicon nitride, silicon carbide, zirconia, molybdenum, tungsten or tantalum.

[0385] While this discussion was based on a injector and feed stream arrangement as previously described, it is understood that the injector may consist of only two passages for introducing and injecting the oxidant and feedstock stream, and they may be in any order with the feedstock stream passing through the central axial bore opening while the feedstock is fed through an annulus surrounding at least a portion of the central oxidant conduit, or the order may be reversed as described above.
