Definitions
- the present disclosure relates to catalysis for use in dewaxing and other hydrocarbon conversion processes and methods of using such catalysts.
- this disclosure relates to a dewaxing catalyst comprising a zeolite component, a metal component for promoting hydrogenation and a hydro thermally stable binder component, and methods of using such catalysts,
- Waxy feedstocks may be used to prepare basestocks having a high viscosity index (VI).
- VI viscosity index
- Dewaxing may be accomplished by means of a solvent or catalytically.
- Solvent dewaxing is a physical process whereby waxes are removed by contacting with a solvent, such as methyl ethyl ketone, followed by chilling to crystallize the wax and filtration to remove the wax.
- Catalytic dewaxing involves chemically converting the hydrocarbons leading to unfavorable low temperature properties to hydrocarbons having more favorable low temperature properties.
- Catalytic dewaxing is a process for converting these long chain normal paraffins and slightly branched paraffins to molecules having improved low temperature properties.
- Catalytic dewaxing may be accomplished using catalysts that function primarily by cracking waxes to lower boiling products, or by catalysts that primarily isomerize waxes to more highly branched products.
- Catalysts that dewax by cracking decrease the yield of lubricating oils while increasing the yield of lower boiling distillates.
- Catalysts that isomerize do not normally result in significant boiling point conversion.
- Catalysts that dewax primarily by cracking are exemplified by the zeolites ZSM-5, ZSM-1 1, ZSM-12, beta and offretite.
- Catalysts that dewax primarily by isomerization are exemplified by the zeolites ZSM-22, ZSM-23, SSZ-32, ZSM-35, ZSM-48 and ZSM-50.
- zeolite catalysts are generally combined with an inorganic oxide binder, such as alumina.
- Catalysts are needed for the upgrading of renewable basestocks for fuels and lubricant applications.
- a catalyst for fatty acid coupling helps production of a highly flexible feedstock.
- this feedstock can then be hydrogenated and/or isomerized using conventional refinery processing, thereby producing high value products consisting of a mixture of fuels, high viscosity, and low viscosity lubricants.
- This product stream can easily be separated using conventional fractionation and distillation equipment.
- the hydrogenation/isomerization catalyst for renewable feedstocks has several challenges to deal with: 1) a highly oxygenated feed (10% oxygen), 2) high heats of reaction, and 3) generation of water which is converted into steam in the reactor.
- the last challenge is of major concern to current dewaxing catalysts because steam can cause issues with the hydrothermal stability of the catalyst and can cause deactivation by dealuminating the zeolite catalyst and/or degradation of the oxide support/binder leading to agglomeration of the metal.
- U.S. Patent Publication No. 201 1/0192766 mentions a supported catalyst comprising a zeolite having a silica to alumina molar ratio of 500 or less, a first metal oxide binder having a crystallite size greater than 200 A and a second metal oxide binder having a crystallite size less than 100 A, wherein the second metal oxide binder is present in an amount less than 15 wt % of the total weight of the catalyst.

- feeds usable in the present disclosure can include any of those that comprise primarily triglycerides and free fatty acids (FFAs).
- FFAs free fatty acids
- the triglycerides and FFAs typically contain aliphatic hydrocarbon chains in their structure having from 8 to 36 carbons, particularly from 10 to 26 carbons, for example from 14 to 22 carbons.
- Types of triglycerides can be determined according to their fatty acid constituents. The fatty acid constituents can be readily determined using Gas Chromatography (GC) analysis.
- GC Gas Chromatography
- This analysis involves extracting the fat or oil, saponifying (hydrolyzing) the fat or oil, preparing an alkyl (e.g., methyl) ester of the saponified fat or oil, and determining the type of (methyl) ester using GC analysis.
- a majority (i.e., greater than 50%) of the triglyceride present in the lipid material is made of C] 0 to C 26 fatty acid constituents, based on total triglyceride present in the lipid material.
- a triglyceride is molecule having a structure identical to the reaction product of glycerol and three fatty acids.
- a triglyceride is described herein as being comprised of fatty acids, it should be understood that the fatty acid component does not necessarily contain a carboxylic acid hydrogen. If triglycerides are present, a majority of triglycerides present in the feed can particularly be comprised of C !2 to C 22 fatty acid constituents, based on total triglyceride content.
- Other types of feed that are derived from biological raw material components can include fatty acid esters, such as fatty acid alkyl esters (e.g., FAME and/or FAEE).
- an acidic catalyst can be used to promote dimerization and oligomerization.
- the dimers and oligomers are branched or having cyclic structures, so that subsequent hydrogenation under the action of the hydrogenation catalyst produces saturated branched or cyclized hydrocarbons than can be naturally very low in wax and require little if any dewaxing.
- action of a basic catalyst produces straight chain products that are subsequently hydrogenated to relatively straight chain hydrocarbons that normally require some dewaxing to make them suitable lube stocks. Dewaxing can be provided by the hydrogenation catalyst, as further described below.
- One method for characterizing the triglycerides in a feedstock is based on the number of carbons in the side chains. While some feedstocks may have consistent numbers of carbons in each side chain, such as in a tristearm feedstock, many types of triglycerides will have variations in chain length between molecules and even within molecules. In order to characterize these variations, the average number of carbons per side chain in the triglycerides can be determined.
- a triglyceride contains three side chains. Each side chain contains a number of carbons, as mentioned above. By averaging the number of carbons in each side chain for the triglycerides in a feedstock, an average side chain length can be determined.
- the average number of carbons (also referred to as average carbon number) per side chain in the feedstock can be used as a comparative value for characterizing products.
- the average number of carbons per side chain in the feedstock can be compared with the average number of carbons in hydrocarbons generated by converting and/or isomerizing the triglyceride-containing feedstock.
- the production of fatty acid coupling products and corresponding hydrogenated products is based on processing of triglycerides within the feed.
- the feed can include at least 10 wt% of feed based on a renewable source or sources, such as at least 25 wt%.
- the renewable portion of the feed is at least 50 wt%, or at least 75 wt%, or at least 90 wt%, or at least 95 wt%.
- Such higher amounts of feed from a renewable source provide an advantage based on the greater amount of renewable material.
- the feed can be entirely a feed from a renewable source, or the feed can include 99 wt% or less of a feed based on a renewable source, or 90 wt% or less, or 75 wt% or less, or 50 wt% or less.
- a temperature increase across the bed of 100°F (55°C) or less. If deoxygenatio of a renewable feed with high oxygen content is performed using a sufficiently reactive catalyst, an exotherm of greater than 100°F across the catalyst bed can be generated. Blending a renewable feed with a portion that does not contain oxygen can reduce the exotherm generated across a catalyst bed used for performing deoxygenation.
- the feedstock can contain a number of components. It can be supplied as a solution in a suitable solvent (particularly a non-reactive solvent such as a hydrocarbon), or the feedstock can be supplied neat.
- the main reactions are thought to be coupling or oiigomerizing the fatty acid components (which produces intermediate products of suitable carbon number to be useful as diesei fuel and lube base stocks upon hydrogenation), and hydrogenating the resulting products to remove functional groups and produce a saturated hydrocarbon.
- the feed may contain various amount of mineral feed as diluent.
- the advantages of increased mineral feed content are largely due to dilution of the renewable feed, as the processing conditions effective for deoxygenation of a renewable feed will have a low or minimal impact on a typical hydroprocessed mineral feed. Therefore, while the deoxygenation conditions are effective for deoxygenation of renewable feeds at a variety of blend ratios with mineral feeds, it may be preferable to have at least 75 wt% of the feed from a renewable source, such as at least 90 wt% or at least 95 wt%.
- One option for increasing the renewable content of a feed while retaining some of the benefits of adding a feed with reduced oxygen content is to use recycled product from processing of renewable feed as a diluent.
- a recycled product from processing a renewable feed is still derived from a renewable source, and therefore such a recycled product is counted as a feed portion from a renewable source.
- a feed containing 60% renewable feed that has not been processed and 40% of a recycled product from processing of the renewable feed would be considered as a feed that includes 100% of feed from a renewable source.
- at least a portion of the product from processing of a renewable feed can be a diesel boiling range product.
- Such a recycled diesel boiling range product will be deoxygenated, and therefore incorporation of the recycled diesel boiling range product in the feed will reduce the exo therm generated during deoxygenation.
- Adding a recycled diesel boiling range product is also likely to improve the cold flow properties of a renewable feed. More generally, any convenient product from processing of a renewable feed can be recycled for blending with the renewable feed in order to improve the cold flow properties and/or reduce the oxygen content of the input flow to a deoxygenation process.
- the amount of recycled product can correspond to at least 10 wt% of the feed to the deoxygenation process, such as at least 25 wt%, or at least 40 wt%, Additionally or alternately, the amount of recycled product in a feed can he 60 wt% or less, such as 50 wt% or less, 40 wt% or less, or 25 wt% or less.
- the feedstock can include at least 10 wt%, such as at least 25 wt%, and particularly at least 40 wt%, or at least 60 wt%, or at least 80 wt%. Additionally or alternately, the feed can be composed entirely of triglycerides, or the triglyceride content of the feed can be 90 wt% or less, such as 75 wt% or less, or 50 wt.% or less.
- the methods described herein are suitable for conversion of triglycerides to lubricant and diesel products in a single reactor, so higher contents of triglycerides may be advantageous. However, to the degree that a recycle loop is used to improve the feed flow properties or reduce the reaction exotherm across catalyst beds, lower triglyceride contents may be beneficial.
- feed dilution can be used to control the exotherm generated across a catalyst bed used for deoxygenation
- some processing options can also impact the exotherm.
- One alternative is to use a less reactive catalyst, so that a larger amount of catalyst is needed at a given liquid hourly- space velocity (LHSV) in order to deoxygenate a feed to a desired level.
- Another option is to reduce the amount of hydrogen provided for the deoxygenation process.
- Still another option could be to introduce additional features into a reactor to assist in cooling and/or transporting heat away from a deoxygenation catalyst bed. in combination with selecting an appropriate amount of product recycle and/or blending of another non-oxygenated feed, a desired combination of a flow characteristics and heat generation during deoxygenation can be achieved,
- Oxygen is the major heteroatom component in renewable base feeds.
- a renewable feedstream based on a vegetable oil, prior to hydro treatment includes up to 10 wt% oxygen, for example up to 12 wt% or up to 14 wt%.
- Such a renewable feedstream also called a biocomponent feedstream, normally includes at least 1 wt% oxygen, for example at least 2 wt%, at least 3 wt%, at least 4 wt%, at least 5 wt%, at least 6 wt%, or at least 8 wt%.
- the renewable feedstream, prior to hydrotreatment can include an olefin content of at least 3 wt%, for example at least 5 wt% or at least 10 wt%.

- a liquid hourly space velocity is from 0.2 to 10 v/v/hr, or 0.5 to 3.0
- a hydrogen circulation rate is 35.6 to 1781 rrrVm J (200 to 10,000 scf/B), particularly 178 to 890.(5 m J /m 3 (1,000 to 5000 scf/B). Further non-limiting examples of conditions are given in working examples.
- Loading of the catalyst is 1 to 30% by weight of the weight of the feedstock in the reactor, for example 2 to 20%, or 5 to 10% by weight.
- the reaction time or residence time can range from 5 minutes to 50 hours depending on types of catalysts used, reaction temperature and the amount (wt %) of catalyst in the reactor.
- a residence time is 10 minutes to 10 hours. Shorter residence time gives better efficiency for reactor usage. Longer residence time ensures high conversion to pure hydrocarbons. Usually an optimized reactor time is most desirable.
- the duration of the reaction is 1-48 hours, 1-20 hours, 12-36 hours, or 24-30 hours.
- the reactions are carried out in a fixed bed reactor, a continuous stir tank reactor, or a batch reactor. In any of these operations, it is advantageous to maintain partial pressure of hydrogen above 300 psi, above 400 psi, above 500 psi, above 600 psi, or above 700 psi.
- carbon dioxide and water generated from the action of the acidic or basic catalyst on the feedstock fatty acids are present in gaseous form, and thus increase the total reactor pressure. Under this condition, it can be important to maintain hydrogen partial pressure.
- this can be achieved by intermittently purging the reactor gas and recharging with hydrogen gas in batch or CSTR operation.
- this can be achieved by withdrawing reactor gas at different locations along the fixed bed reactor; or alternatively by stage injection of hydrogen.
- Other means to maintain hydrogen pressure are also possible.
- the hydrogenation catalyst can introduce branches into the final hydrocarbon products to provide a dewaxmg function.
- the combination of fatty acid coupling (particularly using a basic material as the first catalyst) and hydrogenation will be relatively unbranched hydrocarbons.
- the combination of fatty acid coupling and hydrogenation will be mixtures of branched hydrocarbons (containing one or more branches of various lengths in the range of 1 to 10 carbons) and naphthenics substituted with various lengths of hydrocarbon chains.
- the side chains of the triglycerides contain other types of heteroatoms, such as nitrogen or sulfur, other types of molecules may be generated,
- the stacked bed configuration of the fatty acid coupling catalyst and hydrogenation catalyst will result in production of hydrocarbon molecules that boil in the lubricant boiling range as a primary product, with some production of hydrocarbon molecules that boil in the diesel boiling range.
- the lubricant boiling range molecules correspond to fatty acid coupling products that were formed during conversion of the triglycerides in the feedstock. These fatty acid coupling products are subsequently hydrogenated and isomerized.
- the process of converting triglycerides will typically occur at percentages approaching 100%, less than all of the side chains in the triglycerides may result in formation of coupling products.
- the average number of carbons (i.e., average carbon number) in hvdrogenated molecules derived from triglycerides can be compared with the average number of carbons in the fatty acid side chains of the triglycerides.
- the average number of carbons in hydrocarbon molecules derived from triglycerides in a feed can be at least 1.5 times the average number of carbons in the fatty acid side chains of the corresponding triglycerides, such as at least 1.75 time the average number of carbons in the fatty acid side chains or at least 1.9 times the average number of carbons in the fatty acid side chains.
- the average carbon number of hydrocarbons produced by conversion of feedstock based triglycerides or other fatty esters is two times or more that of the fatty acid components of the feedstock.
- the first catalyst is believed to increase carbon number in the product by a factor of approximately two or more comparing to the carbon numbers of the fatty acid side chains in the feed, by the process of coupling (oligomerization, ketonization, and aldol condensation).
- the product of the reaction described herein is a mixture of hydrocarbons, largely saturated, having a carbon number in the diesel fuel and lube base stock range.
- the reaction product can be hydrofinished by subjecting it to low pressure hydrogen. This process can clean up residual unsaturations and oxygenates that may result when the products are being heated in the presence of the hydrogenation catalyst, which can have some cracking power given that it may contain an acidic carrier such as a zeolite.
- the hvdro finishing can be carried out either in a fixed-bed or in an autoclave reactor.

- the title catalyst (0.6 wt% Pt impregnated 65/35 ZSM-48/alumina) was prepared by the following method: add 245 lbs. of ZSM-48 Si0 2 /Al 2 0 3 90 to the muller. Mull the mixture for ten minutes. Add 162 lbs. of Versal 300 alumina. Mull the mixture for ten minutes after adding all of the alumina. Add 292 lbs. of de-ionized water while mulling. Mull the mixture for forty minutes or until reasonable consistency is achieved. Extrude the mixture o an extruder equipped with a die plate using 1/16" quadrulobe inserts. Dry the extrudate at 250°F in a forced draft oven.
- EXAMPLE 12 Steaming of the 0.6 wt% Pt impregnated 65/35 ZSM-48/ TiQ 2
- Catalyst candidates were first screened through a "severe steaming process" which consisted of steaming each potential lead at 1,000°F for 24 hours in order to examine the effects that exposure to water at high temperatures would have on the crush strength and metal dispersion of each material. Pt dispersions were measured by H 2 chemisorption. A promising lead candidate for this application would maintain its crush strength with minimal metal agglomeration. Catalyst from Example 1 1 was included in the study as a point of reference. The results of the severe steaming study are shown in Table 1 . Table 1 : Summary of Steaming Study Results
- side branches on the backbone of an iso-paraffin have unique chemical shifts and the presence of side-chain causes a unique shift at the tertiary site on the backbone to which it is anchored. It also perturbs the chemical shifts within three sites of the tertiary site, imparting unique chemical shifts ( ⁇ ', ⁇ ' and ⁇ ') to the adjacent sites when they occur in the center of a long backbone.
- the number of free ends of molecules can be estimated by measuring the number of , ⁇ , y and ⁇ carbons.
- Unique shifts also enable measuring the number of pendant side-chains of different length (which are called P-Me, P-Et, P-Pr, and P-Bu).
- the molecular ends that have a side branch at the 2, 3, 4, or 5 sites can also be measured.
- the branching features are particularly valuable in characterizing lube hasestocks.
- the products can be characterized by the 'Tree Carbon Index", which represents the measure of carbon atoms in an average molecule that are epsilon carbons:
- FCi (% epsilon carbons) (Carbon Number) / 100, where the Carbon Number is determined by l3 C NMR as following:
- Carbon Number 2 / ((mole% a carbon + mole% T-Me carbon + mole% T-Et carbon + mole% T-Pr carbon)/ 100)
- C NMR also revealed that the products are significantly free of carbonyl carbon, consistent with high conversions seen by GC.
- the dewaxed products had, on average, 1-3 side chain per molecule, indicating effective dewaxing of the ketone feed.
