Abstract

Flash chemical ionizing pyrolysis (FCIP) process. The FCIP includes mixing an iron source material, an alkali or alkaline earth metal chloride source material, an aqueous phase, and an oil component to form a feed emulsion; introducing the feed emulsion into an FCIP reactor at a temperature greater than about 400°C up to about 600°C, a pressure from 10 to 50 psia and a residence time of 0.1 to 10 seconds, to form an FCIP effluent; and condensing a liquid ionizing pyrolyzate (LIP) from the effluent. The feed emulsion can be free of added solids other than the iron source material, the alkali or alkaline earth metal chloride source material, and any sediment in the oil component.

TITLE: LOW-SOLIDS FLASH CHEMICAL IONIZING PYROLYSIS

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application is anon-provisional of and claims the benefit of and priority to US Ser. No. 62/989,303 filed March 13, 2020. All priority documents are herein incorporated by reference in their entireties.

BACKGROUND

[0002] My earlier patent, US 10,336,946 B2, discloses a process for upgrading heavy oil comprising feeding to a reactor an emulsion of heavy oil, water, and solid particulates comprising a mineral support and an oxide or acid addition salt of a Group 3 - 16 metal, and spraying the feed mixture in the reactor at a high temperature and low pressure.

[0003] My earlier patent, US 10,611,969, discloses flash chemical ionizing pyrolysis of a hydrocarbon using a chemical ionizing additive comprising a mineral support and an oxide and/or acid addition salt of a Group 3-16 metal, e.g., by emulsifying water and an oil component with the additive; introducing the emulsion into a flash chemical ionizing pyrolysis (FCIP) reactor maintained at a temperature greater than about 400°C up to about 600°C and low pressure to form a chemical ionizing pyrolyzate effluent. Also disclosed is a process comprising the further steps of condensing a liquid ionizing pyrolyzate (LIP) from the effluent; combining a feedstock oil with the LIP to form a pyrolyzate-feedstock blend; and thermally processing the blend at a temperature above about 100°C. In these processes. A mineral support such as bentonite is introduced into the reactor system and necessitates the need for solids removal steps and equipment.

[0004] There remains a need for more efficient techniques and systems to refine and process petroleum and other hydrocarbons with ever higher yields of lighter, higher-value hydrocarbon products, while reducing the amount of resid and coke that must be handled. A solution would preferably: reduce the amount of solids introduced into the reactor and/or eliminate or reduce the size of solids removal equipment; be an upstream process to treat crude oil; minimize asphaltene and coke yields; improve saturates and/or aromatics yields; improve the quality of the saturates with increased isomerates production; improve lube oil base stock yields; minimize end product blending requirements; employ mild pressure conditions with a short residence time and high throughput using inexpensive chemical additives; reduce the need for feedstock pretreatment or conditioning to remove catalyst poisons; reduce the need for dewatering and/or desalting; facilitate crude pre-heating by minimizing fouling in the pre heaters; and/or avoid adding hydrogen. SUMMARY

[0005] The present invention discloses improvements to the process applicant refers to herein as “flash chemical ionizing pyrolysis” or FCIP, and a liquid ionizing pyrolyzate or LIP produced by the process. FCIP can be used as a method to pretreat crude oil, optionally without dewatering, to convert asphaltenes from the crude, and form a resulting LIP with a reduced sulfide content, increased isomerates content, and other improvements detailed hereinbelow. [0006] It has been found, unexpectedly, that when the chemical ionizing additive is employed as a system of an iron source material and an alkali or alkaline earth metal chloride source material in an emulsion with water, the additive can be used without any mineral support and moreover, can achieve even higher conversion rates to liquid oil, a further reduction of coke make, and/or a further improved oil quality as reflected in lower density, lower viscosity, lower pour point, or the like, and without introducing excessive solids into the reactor system.

[0007] In one aspect, embodiments according to the present invention provide a hydrocarbon conversion process comprising: providing an iron source material (preferably an unsupported iron source material); providing an alkali or alkaline earth metal chloride source material; providing an aqueous phase; mixing the iron source material, the alkali or alkaline earth metal chloride source material, and the aqueous phase with an oil component to form a feed emulsion (preferably wherein the feed emulsion comprises less than 1 part by weight of added undissolved solids per 100 parts by weight of the oil component); introducing the feed emulsion into a flash chemical ionizing pyrolysis (FCIP) reactor maintained at a temperature greater than about 400°C up to about 600°C and a pressure from 10 to 50 psia to form a chemical ionizing pyrolyzate effluent; and condensing a liquid ionizing pyrolyzate (LIP) from the effluent. [0008] In another aspect, embodiments according to the present invention provide a hydrocarbon conversion process comprising: reacting iron with a mixture of hydrochloric acid and nitric acid in the presence of water (preferably aqua regia) to form an iron source material; mixing the iron source material, an alkali or alkaline earth metal chloride source material, and an aqueous phase with an oil component to form an emulsion; introducing the emulsion into a flash chemical ionizing pyrolysis (FCIP) reactor maintained at a temperature greater than about 400°C up to about 600°C and a pressure from 10 to 50 psia for a residence time of from 0.1 to 10 seconds to form a chemical ionizing pyrolyzate effluent; and condensing a liquid ionizing pyrolyzate (LIP) from the effluent.

[0009] In a further aspect, embodiments of the present invention provide a hydrocarbon refinery process comprising the steps of: preparing a feed emulsion comprising (i) 100 parts by weight of an oil component, (ii) from about 1 to 100 parts by weight of water, (iii) from about 0.01 to 5 parts by weight of an iron source material, and (iv) from about 0.01 to 5 parts by weight of an alkali or alkaline earth metal chloride source material; spraying the feed emulsion in a flash chemical ionizing pyrolysis reactor at a temperature from about 400°C to about 600°C; collecting an effluent from the flash chemical ionizing pyrolysis reactor; and recovering a liquid ionizing pyrolyzate (LIP) from the effluent.

In some embodiments, the LIP has blending characteristics indicative of the presence of ionized species and/or stable free radicals that can induce chemical and/or physical rearrangement of molecules or “normalization” in the blend components. For example, blending the LIP with crude containing asphaltenes results in viscosity changes that are more significant than would be predicted from conventional hydrocarbon blending nomographs, which is consistent with molecular rearrangement of the asphaltene molecules, including disaggregation. Such an unexpected viscosity reduction in turn produces unexpected increases in the efficiencies of thermal processes such as distillation, for example, employing the blend.

[0075] In any embodiment, the feed emulsion comprises from 1 to 100 parts by weight water per 100 parts by weight total primary and blend oil components, preferably 5 to 50 parts by weight water, more preferably 5 to 20 parts by weight water.

[0076] In any embodiment, the reactor temperature is preferably from about 425 °C to about 600 °C, preferably 450°C to 500°C. The reaction pressure is preferably equal to or greater than 10 psia up to 30 psia, more preferably equal to or less than 25 psia, even more preferably 1-1.5 atm absolute. Residence time in the flash chemical ionizing pyrolysis reactor can be from 0.1 up to 10 seconds, preferably from 0.5 to 4 seconds, and especially less than 2 seconds. The introduction step preferably comprises spraying the ionized feed emulsion in the flash chemical ionizing pyrolysis reactor, more preferably atomizing the ionized feed emulsion in the flash chemical ionizing pyrolysis reactor.

[0077] In any embodiment, the oil component can comprise hydrocarbons boiling at temperatures both less than and greater than 562 °C, wherein the LIP is enriched in hydrocarbons boiling at a temperature less than 562 °C, as determined by atmospheric distillation in a 15 -theoretical plate column at a reflux ratio of 5: 1, according to ASTM D2892- 18 up to cutpoint 400°C AET, and by vacuum potstill method according to ASTM D5236-18a above the 400°C cutpoint to cutpoint 562°C AET. The oil component can be a crude oil, gas oil, resid, or a mixture thereof, preferably a heavy oil.

[0078] The process preferably further comprises combining a feedstock oil with the LIP to form a pyrolyzate-feedstock blend and thermally processing the blend at a temperature above about 100°C. The thermal processing can include pyrolysis, distillation, cracking, alkylation, visbreaking, coking, and so on, including combinations thereof. As one example, the process can further comprise supplying at least a portion of the pyrolyzate-feedstock blend as the oil component to the FCIP feed emulsion preparation step, i.e., the thermal processing step consists of or comprises the spraying of the FCIP feed emulsion into the FCIP reactor.

[0079] In embodiments, a hydrocarbon conversion process comprises the steps of: reacting iron with a mixture of hydrochloric acid and nitric acid in the presence of water (preferably aqua regia) to form an iron source material; mixing the iron source material, an alkali or alkaline earth metal chloride source material, and an aqueous phase with an oil component to form an emulsion; introducing the emulsion into a flash chemical ionizing pyrolysis (FCIP) reactor maintained at a temperature greater than about 400°C up to about 600°C and a pressure from 10 to 50 psia for a residence time of from 0.1 to 10 seconds to form a chemical ionizing pyrolyzate effluent; condensing a liquid ionizing pyrolyzate (LIP) from the effluent; and optionally blending the LIP with a feedstock oil and thermally processing the blend.

[0080] In embodiments, a hydrocarbon refinery process comprises the steps of: preparing an ionized feed emulsion comprising (i) 100 parts by weight of an oil component, (ii) from about 1 to 100 parts by weight of water, (iii) from about 0.01 to 5 parts by weight (preferably 0.01 to less than 1 part by weight) of an iron source material, and (iv) from about 0.01 to 5 parts by weight of a chloride source material; spraying the ionized feed emulsion in a flash chemical ionizing pyrolysis reactor at a temperature from about 400°C to about 600°C; collecting an effluent from the flash chemical ionizing pyrolysis reactor; and recovering a liquid ionizing pyrolyzate (LIP) from the effluent. The process can also include combining the recovered LIP with a feedstock oil comprising crude oil or a petroleum fraction selected from gas oil, resid, or a combination thereof to form a pyrolyzate-feedstock blend; distilling, cracking, visbreaking, and/or coking a first portion of the blend; and optionally supplying a second portion of the blend as the oil component in the feed emulsion preparation step. The LIP can exhibit a SARA analysis having higher saturates and aromatics contents and a lower asphaltenes content than the feedstock oil.

[0081] In this process, a proportion of the LIP in the oil component in the flash pyrolysis can be effective to improve yield of liquid hydrocarbons boiling at a temperature below 562°C, relative to separate flash chemical ionizing pyrolysis of the LIP and feedstock oil, as determined by atmospheric distillation in a 15 -theoretical plate column at a reflux ratio of 5: 1, according to ASTM D2892-18 up to cutpoint 400°C AET, and by vacuum potstill method according to ASTM D5236-18a above the 400°C cutpoint to cutpoint 562°C AET.

[0082] Additionally in this process, a proportion of the LIP in the LIP blend in the distillation, cracking, visbreaking, and/or coking step, is effective to improve yield of liquid hydrocarbons boiling at a temperature below 562°C, relative to separate distillation, cracking, visbreaking, and/or coking of the LIP and feedstock oil, as determined by atmospheric distillation in a 15- theoretical plate column at a reflux ratio of 5:1, according to ASTM D2892-18 up to cutpoint 400°C AET, and by vacuum potstill method according to ASTM D5236-18a above the 400°C cutpoint to cutpoint 562°C AET.

[0083] The feedstock oil may preferably be crude oil, which may be desalted or preferably un- desalted, but can also be, for example, gas oil, resid (atmospheric and/or vacuum), and the like, including mixtures or combinations. The LIP is present in a sufficient amount to enhance light oil enrichment and/or to reduce coke make in the thermal processing, e.g., reducing the Conradson carbon content of the thermal processing products. There is no upper limit on the amount of LIP that can be used, but excessive amounts may not be economical. The pyrolyzate- feedstock blend can comprise the LIP in a weight ratio of about 1 : 100 to 1:1, preferably from 1 : 100 to 1 :2, more preferably from about 1 :20 to 1:3, even more preferably from about 1 : 10 to 1:4. Preferably, the percentages of LIP and feedstock oil total 100, i.e., the blend consists essentially of or consists of the LIP and the feedstock oil.

[0084] The thermal processing is preferably distillation, e.g., atmospheric and/or vacuum distillation, and/or flash chemical ionizing pyrolysis (FCIP), which may optionally be used to produce the LIP, but the thermal processing can also be, for example, heating, cracking (thermal and/or catalytic), alkylation, visbreaking, coking, and so on, including combinations in parallel and/or series. [0085] With reference to the embodiment of the invention shown in the simplified schematic flow diagram of FIG. 1, broadly, in process 100, a liquid ionizing pyrolyzate (LIP) 102 is optionally combined with a feed oil 104 in a blending step (not shown) or otherwise fed separately to emulsification in step 106 with iron source material 108, alkali/alkaline earth metal chloride source material 110 and water 112. LIP 102 from any source can be used, preferably from an FCIP process as described herein. The feed oil 104 can be any suitable hydrocarbon liquid, such as, for example, crude oil (including heavy crude oil), which can be desalted or un-desalted, petroleum distillation fractions (especially medium or heavy gas oil) or residue, waste oil, used lube oil, etc.

[0086] . The emulsion from step 106 is supplied to FCIP instep 114 described in more detail hereinafter. One or more effluent(s) are separated in step 116 to obtain solids 118, water 120, LIP 102, and noncondensable gas 124.

[0087] When the feed oil 102 is crude oil, it is advantageously un-desalted since the inorganic components do not appear to adversely impact FCIP 114 and much of the inorganics can be recovered with the solids from FCIP. Since the inorganics are removed in FCIP process 100, the load on the desalter associated with treatment of the crude oil for feed to an atmospheric distillation can be reduced by the amount fed to the FCIP process 100. Moreover, the water content of the crude oil does not impact the FCIP 114 since the feed is in the form of an oil/water emulsion. In fact, it is preferred to use the water or brine from desalting as all or part of the water 112 for the emulsion preparation, thereby reducing the load on the desalter and reducing the amount of water that must be added to the emulsion in step 106. Further, the salt may form a eutectic mixture with one or more of the other additive components, e.g., FeCb, or otherwise enhance the catalytic and/or reactive activity of the iron and chloride source material. [0088] The LIP 102 may optionally be supplied to the blending and/or emulsion step 106 along with or in lieu of another LIP stream from another FCIP source. The remaining LIP 102 can be produced as product 125 and/or optionally thermally processed by heating, distillation, cracking, visbreaking, coking, alkylation, reforming, etc. and/or directly supplied as product(s). If desired, water 120 recovered from the effluent may be recycled to the supply 112 and/or step 106 for the FCIP feed emulsion.

[0089] Preferably, a portion of the oil component in the FCIP feed emulsion from step 106 comprises a recycled portion of the product LIP via line 105. If used, the LIP can be used in the blend in a weight proportion of LIP 102: feed oil 104 of from 1 : 100 to 1 : 1, preferably in an amount from 1 to 40 wt% based on the total weight of the oil components supplied to the FCIP feed emulsion step 106, e.g., 1 to 40 wt% product LIP and 99 to 60 wt% feed oil, preferably 5 to 35 wt % product LIP and 95 to 65 wt% feed oil, more preferably 10 to 30 wt% product LIP and 90 to 70 wt% feed oil, based on the total weight of the oil component, preferably where the percentages of product LIP and feed oil in the LIP blend total 100.

[0090] One advantage of using emulsion from step 106 is that the oil, water, and iron/chloride source materials are intimately mixed prior to vaporization of the oil and water, which are in close contact with the iron/chloride additives, and the iron/chloride additives are already well- dispersed in liquid, promoting fluidization in the gas phase. For example, iron and/or chloride ions can associate with charged molecules in the oil component in the feed emulsion at low temperature, e.g. hetero atoms in asphaltene constituents, and thereby target these species for reaction upon decomposition or catalytic activation of the associated ion at the high temperature FCIP conditions.

[0091] Another advantageous feature of the present invention is that in some embodiments the emulsion from step 106 can have a viscosity that is lower, preferably an order of magnitude lower, than the corresponding oil components, which facilitates preparation, pumping, spraying, conversion, yield, etc., and can avoid adding solvent or diluent. For example, the feed mixture may be an emulsion having an apparent viscosity at 30°C and 100 s ¹ at least 30% lower than the oil component alone. In embodiments, the emulsion has a viscosity of less than or equal to about 50 Pa-s (50,000 cP) at 50°C, or less than or equal to about 20 Pa-s at 50°C, or less than or equal to about 1 Pa-s (1000 cP) at 50°C, or less than about 500 mPa-s at 50°C. Accordingly, the emulsion may include heavy oil emulsified with water and the finely divided solids to produce a pumpable emulsion which facilitates adequate and uniform injection of the feed mixture into the pyrolysis chamber.

[0092] Also, in some embodiments the emulsion from step 106 can have a high stability that inhibits separation into oil or water phases and solids precipitation, which might otherwise result in a buildup of asphaltenes, wax, mineral particles, etc. The stability can facilitate advance preparation and storage of the emulsion 106. For example, the feed emulsion can have an electrical stability of equal to or greater than 1600 V, when determined according to API 13B-2 at 130°C, preferably greater than 1800 V or even greater than 2000 V. If desired, the emulsion may further comprise an emulsifying agent such as a surfactant or surfactant system. Preferably, the emulsion is substantially free of added surfactant.

[0093] In some embodiments, the process comprises first mixing the feed oil 104 (or blend with LIP 102) and the iron source material 108, and then mixing in the water 112. The alkali/alkaline earth metal chloride source material 110 can be present in the water 112, e.g., as a brine, and/or in the feed oil 104, e.g., un-desalted crude, in the iron source material 108, e.g., as a chloride or as a pretreatment in any support material, or it can be separately added. Preferably, the process further comprises passing (e.g., pumping) the feed emulsion through a line to the reactor 114, as opposed to mixing the oil, water, and/or chloride/iron source materials together in the reactor 114, e.g., introducing them separately and/or at a nozzle used for spraying the mixture. In embodiments, the heavy oil is combined with the water and the chloride/iron source material(s) to form the feed mixture at a temperature of about 25°C to about 100°C, e.g., 30°C to 95°C. The emulsion from step 106 may be fed to the FCIP reactor 114 at a relatively high temperature to minimize viscosity and enhance rapid heating in the pyrolysis chamber, but below boiling, e.g., 30 °C to 70 °C or 40°C to 60°C.

[0094] An exemplary process according to embodiments of the present invention comprises the steps of preparing the FCIP feed emulsion 106 comprising (i) 100 parts by weight of the oil component which comprises from 1 to 50 wt% of the LIP, preferably 5 to 40 wt% LIP, based on the total weight of the oil component, (ii) from about 1 to 100 parts by weight of the water component 412, (iii) from about 0.01 to 5 parts by weight (preferably 0.01 to 1 part by weight) iron source material 108 (preferably comprising iron oxide, iron hydroxide, iron oxide- hydroxide, iron chloride, or a mixture thereol), and (iv) from about 0.01 to 5 parts by weight alkali/alkaline earth metal chloride source material 110 comprising alkali or alkaline earth metal chloride such as NaCl, KC1, LiCl, MgCh. CaCh. BaCh. or a mixture thereof; spraying the FCIP feed emulsion from step 108 in a pyrolysis reactor 114 at a temperature from about 425°C to about 600°C (preferably about 450°C to about 500°C); collecting effluent(s) 116 from the pyrolysis reactor 114; recovering a product LIP 102, 125 from the effluent 116; and optionally supplying a portion 105 of the LIP 102 to the feed emulsion preparation step 106. [0095] Higher amounts of water in the emulsion 106, e. g., more than 50 parts by weight, particularly when processing paraffins, tend to produce more hydrocarbon gases, which may be preferred where olefin production is preferred. On the other hand, when processing asphaltenes, higher amounts of water can control cracking, thereby limiting gas formation and coke make. Optimally, targets of about 15 parts by weight of water per 100 oil are used for the FCIP processing of asphaltene-rich crudes, and about 10 parts by weight of water per 100 oil are used for the FCIP processing of paraffinic crudes.

[0096] In embodiments, the absolute pressure in the FCIP reactor 114 is from below atmospheric or about atmospheric up to about 5 atm, or preferably up to about 3 atm, or more preferably up to about 2 atm, or especially up to about 1.5 atm (7-8 psig). For example, the pressure in the FCIP reactor 114 can be about 10 to 50 psia, or about 1 to 3 atm, preferably 10 to 30 psia, more preferably 1 to 1.5 atm. The higher pressures are less preferred since they require more expensive equipment to handle them and may inhibit reactions necessary for forming the conversion-promoting and/or coke-inhibiting components in the product LIP 102. [0097] The FCIP reactor 114 is operated and/or pyrolyzate exits from the reactor 114 preferably at a temperature between about 425°C and about 600°C, more preferably between about 450°C and about 500°C. The lower temperatures tend to favor more liquid hydrocarbon products and less gas, but total conversion may also be lower. Conversely, the higher temperatures tend to favor more conversion but hydrocarbon gas formation, including olefins, is greater and liquid hydrocarbon yield is less. The temperature depends on the hydrocarbon products desired: for greater liquid hydrocarbon yields, a temperature of 450°C to 500°C is preferred, 450°C to 480°C more preferred; for higher olefin and/or other light hydrocarbon yields, 500°C to 600°C is preferred.

[0098] In some embodiments, the heating of the reactor 114 and/or emulsion 106 can be direct by contact with a hot gas such as a combustion effluent or superheated steam, and/or in indirect heat exchange relationship with the combustion gas or steam, or by using an electrical or induction heating. In direct heating, the flue gas or superheated steam preferably comprises less than about 3 vol% molecular oxygen, or less than about 2 vol% molecular oxygen, or less than about 1 vol% molecular oxygen.

[0099] In some embodiments, the process comprises injecting the emulsion into the reactor, e.g., using an atomizing nozzle, and in some embodiments the injection is into a stream of combustion flue gases or other hot gas such as superheated steam in direct heat exchange to promote rapid heating and mixing, e.g., countercurrently sprayed upstream against an oncoming flow of the steam or combustion gas, for example, spraying the emulsion downwardly against an upward flow of the hot gas from below. If desired the steam, combustion flue gases or other hot gas can be introduced into a lower end of a reactor vessel housing the pyrolysis zone, e.g., through a gas inlet through a side or bottom wall of the reactor. Regardless of heating mode, when sprayed downwardly into the reactor, the residue and solids can accumulate in the bottom of the reactor, and periodically or continuously removed from the reactor, for example, through an outlet for continuous or periodic removal of the solids, e.g., using a rotary valve in the outlet.

[0100] In some embodiments, especially where the feedstock oil is a heavy crude oil or very heavy crude oil, the pyrolyzate vapor phase preferably comprises a condensate upon cooling having an overall API gravity greater than 20 °API or greater than 22.3 °API or greater than 26 °API. In some embodiments, the process further comprises cooling the pyrolyzate vapor phase to form a condensate, and collecting the condensate, wherein the condensate has an overall API gravity greater than 20° or greater than 22.3°.

[0101] In some embodiments, the pyrolyzate vapor phase comprises hydrocarbons in an amount recoverable by condensation at 30°C of at least about 70 parts (preferably 80 parts, more preferably 90 parts) by weight per 100 parts by weight of the oil in the feed mixture, and especially greater than 100 parts by weight liquid hydrocarbons per 100 parts by weight of the oil. Liquid hydrocarbon yields in excess of 100% of the feed oil are made possible by incorporating hydrogen and/or oxygen (from the water), especially hydrogen, into the product oil, and minimizing gas and residue formation. In some embodiments, the pyrolyzate vapor phase comprises less than 5 vol% of non-condensable (30°C) hydrocarbon gases based on the total volume of hydrocarbons in the pyrolyzate vapor phase (dry basis).

[0102] In embodiments, the feed oil 104 can be a crude oil, including heavy crude oil, extra heavy crude oil, tar, sludge, tank bottoms, spent lubrication oils, used motor crankcase oil, oil recovered from oil based drill cuttings, etc., including combinations and mixtures thereof. In embodiments, the feed oil has an API gravity of less than 22.3° API or less than 20° API or less than 10°API. In embodiments, the heavy oil has a viscosity at 50 °C greater than 10,000 cP, or greater than 50,000 cP, or greater than 100,000 cP, or greater than 300,000 cP, whereas the LIP 422 can have a viscosity at 50 °C less than 1000 cP, or less than 100 cP, or less than 30 cP. [0103] As mentioned above, the feed oil need not be dewatered or desalted and can be used with various levels of aqueous and/or inorganic contaminants. Any water that is present, for example, means that less water needs to be added to form the emulsion 106 to obtain the desired water: oil ratio. The salts and minerals that may be present in crude oil do not appear to adversely affect results, and may provide an alkali/ alkaline earth metal chloride source material in addition to or in lieu of the added alkali/alkaline earth metal chloride source material 110. These embodiments are particularly advantageous in being able to process waste emulsions or emulsions such as rag interface that is often difficult to break. Considering that the industry goes to great lengths to break emulsions into clean oil and water phases, feeding such emulsions in the feed mixture herein to the reactor can avoid the need to break such emulsions altogether, or at least reduce the volume of emulsion that must be separated. For example, the rag layer that often forms at the interface between the oil and water, that is often quite difficult to separate, can be used as a blend component in the feed emulsion step 106.

[0104] In some embodiments of the present invention, a hydrocarbon refinery process comprises the steps of: (a) combining an LIP with a feedstock oil to form an LIP blend comprising from 1 to 50 wt% LIP and 99 to 50 wt% feedstock oil, preferably 5 to 35 wt % LIP and 95 to 65 wt% feedstock oil, more preferably 10 to 30 wt% LIP and 90 to 70 wt% feedstock oil, based on the total weight of the oil component, preferably where the percentages of LIP and feedstock oil total 100; (b) preparing an FCIP feed emulsion comprising (i) 100 parts by weight of a first portion of the LIP blend, (ii) from about 1 to 100 parts by weight of a water component, (iii) from about 0.01 to 5 parts by weight (or 0.01 to 1 part by weight) iron source material 108 (preferably comprising iron oxide, iron hydroxide, iron oxide-hydroxide, iron chloride, or a mixture thereof, more preferably where the iron source material is unsupported), and (iv) from about 0.01 to 5 parts by weight chloride source material 110 comprising alkali or alkaline earth metal chloride such as NaCl, KC1, LiCl, MgCh. CaCh. BaCh. or a mixture thereof; (c) spraying the FCIP feed emulsion in a flash pyrolysis reactor at a temperature from about 425°C to about 600°C, preferably 450°C to 500°C; (d) collecting an effluent from the flash pyrolysis reactor; (e) recovering a product LIP from the effluent; (f) incorporating at least a portion of the product LIP into the LIP blend; and (g) distilling a second portion of the LIP blend. The feedstock oil preferably comprises crude oil, more preferably un-desalted crude oil, e.g., the process may further comprise water washing to desalt the second portion of the LIP blend, and distilling the desalted second portion of the LIP blend in step (g).

[0105] In some embodiments of the present invention, a hydrocarbon refinery process comprises the steps of: (a) preparing an FCIP feed emulsion comprising (i) 100 parts by weight of an oil component, (ii) from about 5 to 100 parts by weight of a water component, (iii) from about 0.01 to 5 parts by weight iron source material 108 (preferably comprising iron oxide, iron hydroxide, iron oxide-hydroxide, iron chloride, or a mixture thereof, more preferably where the iron source material is unsupported) and (iv) from about 0.01 to 5 parts by weight alkali/alkaline earth metal chloride source material 110 comprising alkali or alkaline earth metal chloride such as NaCl, KC1, LiCl, MgCh. CaCh. BaCh. or a mixture thereof; (b) spraying the FCIP feed emulsion in a pyrolysis reactor at a temperature from about 425°C to about 600°C, preferably 450°C to 500°C; (c) collecting an effluent from the pyrolysis reactor; (d) recovering LIP from the effluent; (e) combining the recovered LIP with a feedstock oil comprising a petroleum fraction selected from medium weight gas oil, heavy gas oil, resid, or a combination thereof to form an LIP blend; and (f) distilling, cracking, visbreaking, and/or coking the LIP blend. Preferably, the oil component in the feed emulsion from the preparation step (a) comprises the petroleum fraction used in step (d), e.g., the feed emulsion from step (a) may comprise the LIP blend from the combining step (e).

[0106] The LIP 102 is thus produced from a flash chemical ionizing pyrolysis (FCIP) process 114 (see FIGs. 7-9 discussed below), e.g., the process referred to as catalytic pyrolysis in US 10,336,946 B2. In any embodiment, the FCIP preferably comprises the steps of preparing an FCIP feed emulsion comprising (i) an oil component, (ii) a water component, and (iii) finely divided solids comprising a mineral support and the iron source material (preferably comprising iron oxide, iron hydroxide, iron oxide-hydroxide, iron chloride, or a mixture thereof), preferably 100 parts by weight of the oil component, from about 1 to 100 parts by weight of the water component, and from about 1 to 20 parts by weight of the finely divided solids; spraying the FCIP feed emulsion in a pyrolysis reactor, preferably at a temperature from about 425°C to about 600°C, preferably 450°C to 500°C; collecting an effluent from the pyrolysis reactor; and recovering a product LIP from the effluent.

[0107] In any embodiment, the FCIP preferably comprises the steps of preparing an FCIP feed emulsion comprising (i) an oil component, (ii) a water component, (iii) unsupported iron source material, and (iv) an alkali or alkaline earth metal chloride source material, wherein the feed emulsion comprises less than 1 part by weight added solids per 100 parts oil; spraying the FCIP feed emulsion in a pyrolysis reactor, preferably at a temperature from about 425°C to about 600°C, preferably 450°C to 500°C; collecting an effluent from the pyrolysis reactor; and recovering a product LIP from the effluent.

[0108] In any embodiment, the FCIP feed emulsion may preferably comprise from about 20 to about 50 parts by weight of the water, and/or from about 0.01 to about 1 part by weight of each of the iron and alkali/alkaline earth metal chloride source materials, per 100 parts by weight LIP -feedstock blend or other feed oil.

[0109] In embodiments, the iron/chloride source materials may preferably comprise or be prepared as the finely divided solids and/or any of those catalysts disclosed in my earlier patent, US 10,336,946 B2, which is hereby incorporated herein by reference in jurisdictions where permitted. For example, the iron/chloride source materials can comprise the finely divided solids comprising clay and/or a derivative from a clay, such as montmorillonite, for example, bentonite. The mineral support can be any other mineral disclosed in the ‘946 patent, including processed drill cuttings, albite, and so on. The metal can comprise a Group 3 - 16 metal, e.g., iron, lead, zinc, or a combination thereof, preferably a Group 8 - 10 metal, e.g., iron, cobalt, nickel or the like. In any embodiment, the finely divided solids may comprise an oxide and/or acid addition salt of a Group 8 - 10 metal supported on clay, preferably iron oxide, iron hydroxide, iron oxide-hydroxide, iron chloride, or a mixture thereof.

[0110] Preferably, the iron source material comprises iron oxide, iron hydroxide, iron oxide- hydroxide, iron chloride, or a mixture thereof, more preferably where the iron source material is unsupported, and a source of a chloride salt. When present, the montmorillonite or other support is preferably a non-swelling clay such as calcium bentonite. The iron/chloride source materials are preferably the product of the method comprising the steps of: (a) treating iron with an aqueous mixture of hydrochloric and nitric acids to form a solids mixture of iron oxide, iron hydroxide, iron oxide-hydroxide, and iron chloride, preferably wherein the mixture has limited solubility in water and is acid soluble, (b) treating montmorillonite, preferably calcium bentonite, with an alkali or alkaline earth metal chloride brine, preferably NaCl brine and drying the treated montmorillonite; (c) combining the solids mixture with the treated montmorillonite to load the iron oxide, iron hydroxide, iron oxide-hydroxide, iron chloride mixture on the montmorillonite, preferably by incipient wetness or by adding an aqueous slurry of the solids mixture to the essentially dry montmorillonite; and (d) heat treating the loaded montmorillonite at a temperature above 400°C up to the FCIP temperature, preferably 400°C to 425°C (see FIGs. 5-6 discussed below).

[0111] Preferably, the iron and alkali metal/alkaline earth metal chloride source materials comprise iron compound derived from the treatment of iron with an aqueous mixture of hydrochloric and nitric acids to form a solids mixture of mixed valences of iron and iron oxides, iron hydroxides, iron oxide-hydroxides, and iron chlorides. The admixture of one part by weight iron and 1-2 parts by weight aqua regia (HCkFfeCkHNCb at 3:2:1 by weight) forms hematite, magnetite, beta-iron oxide hydroxide, and chlorides, which is consistent with the reddish black coloration of the solids that is observed. The aqua regia is preferably slowly added to the iron, or may be added in several aliquots, to avoid excessive heat formation and reactant vaporization since the reaction is very exothermic. The proportion of iron may be increased somewhat, but too much iron may form insufficient ferric material as indicated by a generally brown or rust color. Greater proportions of aqua regia do not yield much if any benefit and thus may lead to lower yields of the solids mixture and/or excessive reagent costs. The admixture of solids can also contain elemental iron, since the iron may be present in excess. Also, other iron chlorides, nitrates, nitrites, oxides, oxychlorides, hydrochlorides, hydroxides, hydrates or combinations and/or mixtures of these may also be present. For example, treatment of iron with aqua regia may in theory form ferrates such as tetrachloroferrate (III), hexachloroferrate (VI) and so on. Further, since water is present, these compounds may be hydrated to varying degrees, e.g., especially upon slurrying with water, or decomposed by the water.

[0112] The iron source materials preferably have limited solubility, e.g., less than 50 wt% will dissolve in hot water when mixed at a ratio of 1 g solids to 30 ml distilled water, preferably less than 40 wt%; and the iron source material is preferably acid soluble, e.g., more than 50 wt% will dissolve in 20 wt% aqueous HC1 when mixed at a ratio of 1 g solids to 30 ml aqueous HC1, preferably at least about 65 wt%. The solids mixture may be dried, e.g., in an oven at a temperature above 100°C, for example, 100°C to 150°C, and ground as needed. When the iron source materials is slurried in water and partially dissolved, the aqueous solution phase may comprise an excess of chloride ions, e.g., a molar ratio of chloride to total dissolved iron that is greater than 3:1, such as between 4 and 5 moles chloride per mole of solubilized iron. The aqueous phase of the slurry may also contain nitrite and/or nitrate in lesser amounts, e.g., 0.04- 0.8 mole nitrite per mole of dissolved iron and/or 0.01-0.2 mole nitrate per mole of iron. [0113] FIG. 2 shows the preparation of the iron source compound in exemplary embodiments according to method 200. In the summarized method 200, iron 202 is treated with acid 204, which may be an aqueous mixture of HC1 and HNCb, in iron source material preparation step 206. In step 206, finely-divided elemental iron 202, e.g., 100 mesh carbon steel or high purity iron shavings, are admixed with aqua regia 204, preferably an excess where the total moles of HC1 and HNCb are at least 3-6 times greater than the moles of iron, e.g., at a weight ratio of 1:1-2 (Fe: aqua regia) where the aqua regia has a weight ratio of nitric acid:hydrochloric acid:water of about 1:3:2. The aqua regia is preferably added in multiple aliquots while stirring, and the temperature may increase, e.g., to about 95°C or greater, forming .

[0114] The solid iron compound can be recovered from the aqueous phase, e.g., by filtration, water washing, and drying, for example in an oven as shown in step 208. In step 210, the recovered solids can be ground, e.g., to pass a 100 mesh screen, preferably a 325 mesh or 400 mesh screen.

[0115] The aqua-regia-treated Fe solids (“AR-Fe”) at this point can comprise a complex mixture of iron oxide, iron hydroxide, iron oxide-hydroxide, iron chloride, or a mixture thereof, with the iron in various valence states, e.g., Fe(0), Fe(II), Fe(III), and so on. Primarily, solids comprise hematite, magnetite, and beta-ferric oxide hydroxide. The AR-Fe unexpectedly has a low fractional solubility in water so that no more than 40 wt%, preferably no more than about 35 wt% or 30 wt%, dissolves and/or digests in an aqueous mixture of 1 g AR-Fe in 30 ml total mixture (33.33 g/L) at 100°C, but has a high fractional solubility in 20 wt% aqueous hydrochloric acid such that at least 90 wt%, preferably at least about 95 wt % or 98 wt%, dissolves and/or digests in an aqueous mixture of 1 g AR-Fe in 30 ml total mixture (33.33 g/L) at 100°C.

[0116] The method 300 seen in FIG. 3 shows the alternative preparation of a supported iron/chloride source compound. Brine 302, preferably 1M sodium chloride, is admixed in step

304 with calcium bentonite 306, preferably passing through a 100 mesh screen. Preferably, the weight ratio of Ca-bentonite to brine is 1:2. The mixture can be stirred, e.g., for 1 h, and allowed to stand, e.g., for 16-24 h. In step 308, the excess brine is discarded, e.g., by decantation and/or filtration, and in step 310 the solids are dried, e.g., dried in an oven at 120-130 ^°C for 4-6 h. When the NaCl-bentonite is dry, it can be optionally ground in step 312, e.g., to pass through an 80 mesh screen. Separately the iron compound is prepared. In step 320, finely-divided elemental iron 322 is admixed with aqua regia 324. In step 326, the solid iron compound can be recovered and dried. In step 328, the recovered solids can be ground as desired. In step 330 the solids are slurried in water, e.g., at 4 weight percent solids. Then, in step 332 the slurry from step 330 is admixed with the dry, ground NaCl-bentonite from step 312, e.g., at a weight ratio of 2:3 (slurry: NaCl-bentonite) to load the AR-Fe on the NaCl-bentonite by incipient wetness. The mixture from step 332 is then dried and calcined, e.g., at 400°C for 2 h in step 334, cooled and ground in step 336, e.g., to pass an 80 mesh screen, and recovered as the supported iron-based solids 338.

[0117] While not wishing to be bound by theory, as mentioned above one advantage of using a feed emulsion is that iron and/or chloride ions can pre-associate with heteroatoms in the asphaltene molecules and thereby target these species for reaction upon decomposition and/or catalytic activation of the associated ions at the high temperature FCIP conditions. The ionized species present in the emulsion presents a level of molecular-scale pre-mixing of oil, water, catalysts and other reactants that cannot occur where the reactants and catalysts are supplied separately to the reactor.

[0118] While not wishing to be bound by theory, it is believed that hydrogen radicals and/or molecular hydrogen are generated in situ during flash pyrolysis by reaction and/or catalysis of one or more iron compound(s) at the pyrolysis conditions, e.g., at 450 - 500 °C. For example, hydrogen may be formed by the decomposition of ferric chloride in the presence of steam, according to the following reactions, e.g.:

FeCb FeCl₂(s) + Cl⁺

Cl⁺ + 2H2O HCIO + H⁺

Here, the formation of hydrogen may be favored due to an excess of water (steam).

[0119] Ferric chloride can be formed by the decomposition of iron chloride compounds in the iron source material, e.g., FeOCl may decompose into FeCb, according to the equation:

3FeOCl Fe₂Cb + FeCb.

[0120] Ferric chloride can also be formed by the decomposition of the chloride source material to form HC1, which then reacts with iron oxides, e.g., according to the reactions:

NaCl + H₂0 (Superheated steam) HC1 + NaOH Fe203 + 6HCL 2FeCb + 3H₂0

[0121] In turn, organic carboxylic acids can be decarboxylated according to the reactions:

R-COOH + NaOH R-COONa + HOH R-COONa + NaOH RH + Na₂C0₃ (s) where R is a hydrocarbyl.

[0122] In addition to the chemical production of hydrogen radicals by decomposition, FeCh per se and bentonite (if present) can function as Lewis and/or Bronsted acids, and thus in theory can initiate ionic cracking reactions to form liquid ionizing pyrolyzate. Another possibility in theory is that iron compound(s) having higher oxidation states relative to Fe(III) may be formed during the preparation of the iron compounds with aqua regia and/or during heat treatment, e.g., hexachloroferrate ion (Fe(VI)Cb)³ which might also help form ions and/or free radicals to propagate thermal and/or catalytic cracking reactions.

[0123] Furthermore, iron compounds such as magnetite, hematite, iron oxide hydroxide, iron oxychloride, ferrates, and the like, can act as catalysts per se in various hydrocarbon reactions. [0124] While not wishing to be bound by theory, it is believed that FCIP using the Fe/Cl system at low pressure and a specific range of temperatures achieves extensive conversion of heavy hydrocarbons such as asphaltenes and/or resins to lighter hydrocarbons, and removal of heteroatoms such as nitrogen, sulfur, metals, etc., by reactions normally seen in high pressure catalytic cracking and hydrocracking, e.g., isomerization, cracking, dealkylation, aromatic saturation, decyclization, etc. For example, there is evidence that sulfur is both reduced, presumably by hydrogen radicals, and oxidized, presumably by reaction with HCIO that is formed, as indicated above, by the reaction between the chlorine radical liberated from the iron chloride decomposition and the water that is present in the emulsion. The LIP product is unexpectedly characterized by low noncondensable gas yield, e.g., only small quantities of methane may be formed; the light products may be primarily C1-C6 hydrocarbons; small quantities of or no C4+ olefins may be seen; and there may be significant formation of branched chain alkanes, isomerates, dealkylated aromatics, and naphthene cracking products. At the same time, the yield of coke can be minimized.

[0125] The montmorillonite support, if present, is preferably a non-swellable bentonite such as calcium bentonite. The bentonite is preferably treated with a chloride brine to replace calcium ions with the cation, e.g., by treating the bentonite with 1 molar NaCl or other chloride brine. The treated bentonite may then be dried, e.g., in an oven at a temperature above 100°C, for example, 100°C to 150°C, and ground as needed to prepare it for loading with the iron/chloride source materials slurry by incipient wetness. The loading is thus achieved by mixing the iron/chloride source materials slurry with the dried chloride brine-treated bentonite, which may form a paste. In this mixture, Na ions in the bentonite may theoretically be displaced with iron and/or iron complex cations to form, e.g., possible species such as Fe(II)X-(0-Si- bentonite) and/or Fe(III)X2(-0-Si-bentonite), where X is an anion. The mix of iron compound and dried, chloride brine-treated bentonite is then preferably heat treated or calcined. Heat treating the finely divided solids involves heating at a temperature above 200°C, such as from about 300°C up to 600°C, for a period of time from less than 1 minute up to 24 hours or more, e.g., 1 to 16 hours. Heating at a temperature above 400°C for a period of 4 to 6 hours is preferred. High temperatures above 400°C are preferred to activate the iron/chloride source materials, and may result in isolated Lewis and/or Bronsted acid sites in the bentonite being formed and/or other hydrate compounds, e.g., iron compound hydrates, may be dehydrated. Lower temperatures may result in insufficient activation or require longer periods of heating. Substantially higher temperatures may cause undesirable reaction, volatilization, and/or deactivation of the chemical species in the solids. Preferably, the heat treatment is at a temperature lower than the FCIP temperature, which may avoid premature reaction and/or deactivation of the solids material prior to FCIP, more preferably the heat treating is at a temperature of equal to or greater than 400°C up to a temperature equal to or less than 425°C. [0126] Although not wishing to be bound by theory, it is believed salts or ions present in the iron/chloride source materials can form a eutectic mixture with one or more metal compounds or reaction products thereof, especially where the metal compound melts or boils at the heat treatment temperature and the eutectic mixture is non-volatile. For example, where the iron compound includes or forms FeCb, which has a normal boiling point of 315°C and is thus normally quite volatile at 400°-425°C, the presence of NaCl or another salt may form a eutectic mixture of FeCb-NaCl with substantially lower volatility. This allows the FeCb to remain on the support during heat treatment at 400°-425°C and to be available as a reactant and/or catalyst at a higher pyrolysis temperature. Other iron compounds such as nitrates and/or nitrites may or may not decompose during the heat treatment step, e.g., to form iron oxides. In theory, similar eutectic systems such as FeCb-Na-bentonite may also form. Also, the iron compound resulting from the aqua regia treated iron has unexpectedly limited solubility in water suggesting that other complexes may be formed which could also limit volatility during heat pretreatment. As an example, the aqua regia-treated iron compounds might form covalent bonds with the bentonite, e.g., Fe(III)Ch(-0-Si-bentonite), to limit premature volatility. When used, the solids mixture of iron compounds or other iron source may be loaded on the bentonite in an amount from 1 mg/kg to 10 wt%, for example, from about 1000 mg/kg to 5 wt%, preferably 2-4 wt%, based on the total weight of the finely divided solids.

[0127] Liquid ionizing pyrolyzate (LIP) products obtained when a feedstock oil is processed by FCIP according to embodiments disclosed herein, especially when an oil with high contents of asphaltenes and/or resins is processed, include various medium-length hydrocarbon fractions having from about 12 to about 30 carbons, and various light oil fractions having from about 6 to 12 carbons. The LIP is thus enriched in hydrocarbons similar to those seen in catalytic and/or hydrocracking products.

[0128] Additionally, the LIP from the FCIP disclosed herein has an unexpectedly low viscosity for its density, compared to other hydrocarbons, suggesting the presence of relatively high levels of isomerates. Moreover, blends of the LIP with other crude oils, heavy oils, resids, and the like also have an unexpectedly low viscosity compared to conventional crude oil blends. Applicant is not bound by theory, but believes there may be ionized species in the LIP such as stable radicals that can inhibit asphaltene aggregation and/or decyclize asphaltenes, which is reflected in a significant reduction in coking tendency. The asphaltenes and other hydrocarbon molecules subjected to FCIP can form relatively stable free radical species, and can also form hydrogen donor species such as hydroaryl compounds. Some rearrangement of molecules appears to occur at ambient temperatures upon blending, whereas at moderate thermal processing temperatures, e.g., 100-250°C, the free radicals and hydrogen donors can facilitate conversion to saturates, aromatics, and lube oil base stock molecules, and reducing the amount of Conradson carbon residue and coke make.

[0129] In any case, when a feedstock oil is blended with the LIP, the viscosity reduction and reduced tendency to form coke results in unexpected improvements in thermal processing. For example, a crude-LIP blend can be heated more rapidly, e.g., during preheating for feed to the distillation column, since fouling from coke formation and deposition is markedly reduced. Distillation of a crude-LIP or resid-LIP blend results in liquid oil yields that are substantially and synergistically higher, and resid yields that are substantially and synergistically lower, than could be obtained by separate distillation of the LIP and crude or resid. Flash pyrolysis of a crude-LIP or resid-LIP blend, by FCIP as described herein, or otherwise, likewise results in similarly increased yields of liquid oil products and decreased yields of coke and also noncondensable gases. Unexpectedly, the resid from thermal processing of such LIP -modified blends exhibits a remarkably low viscosity, suggesting it contains an unusually high proportion of lube oil base stock. Moreover, the production of olefins by FCIP can be controlled by the selection of appropriate operational parameters, e.g., increasing the water content in the emulsion feed to the pyrolysis reactor and/or increasing the pyrolysis temperature can produce relatively larger amounts of olefins such as ethylene and propylene.

[0130] With reference to the embodiment of the invention shown in the simplified schematic flow diagram of FIG. 4, in FCIP process 400, feed oil 402 and liquid ionizing pyrolyzate (LIP) from stream 404 are optionally blended in step 406 or otherwise fed separately to emulsification in step 408 with chloride source 409, iron source 410 and water 412. The emulsion from step 408 is supplied to FCIP step 414. One or more effluents are separated in step 416 to obtain solids 418, water 420, LIP 422, and noncondensable gas 424.

[0131] With reference to the embodiment of the invention shown in the simplified schematic flow diagram of FIG. 5, a hydrocarbon refinery process 500 comprises combining a liquid ionizing pyrolyzate (LIP) 502 from FCIP 504 with a feed oil 506 in step 508 to form an LIP blend comprising the LIP. A first portion 520 of the LIP blend from 508 is supplied for FCIP 504, and a second portion 509 for distillation 514.

[0132] The LIP can be used in the blend in a weight proportion of LIP 502: feed oil 502 of from 1:100 to 1:1, e.g., or from 1:20 to 1:2, preferably in an amount from 1 or 5 to 35 wt%, e.g., about 10 to 30 wt%, based on the total weight of the feed oil 506 and LIP 502 supplied to the blending step 508. Lesser amounts of the LIP have diminishing improvement of the blend, whereas higher amounts may not be economically attractive.

[0133] Surprisingly, it has been found that a blend of the LIP and crude oil can have a substantially lower viscosity than would be expected from traditional API viscosity prediction methods for blends.

[0134] The first LIP blend portion 520 can be pyrolyzed in FCIP 504. In step 522, there is prepared an FCIP feed emulsion comprising (i) 100 parts by weight of the first portion 520 of the LIP blend, (ii) from about 1 to 100 parts by weight water 528, (iii) from about 0.01 to 5 parts by weight of the iron source material 526, and (iv) from about 0.01 to 5 parts by weight of the chloride source material 525, e.g., from about 5 to about 50 parts by weight of the water 528, and from about 0.05 to about 1 parts by weight each of the iron/chloride source materials 525, 526, per 100 parts by weight of the LIP blend from step 508. In step 504, the FCIP feed emulsion from 522 is injected, preferably sprayed, in a pyrolysis reactor at a temperature from about 425°C to about 600°C. An effluent 530 is collected from the pyrolysis reactor, a product LIP 502 is recovered from the effluent, and at least a portion is incorporated into the LIP blend in step 508 as mentioned above. [0135] Feed oil 524, which can be the same feed oil as 506 or another oil source can optionally be supplied to the emulsion step 522 along with or in lieu of stream 520. Where blend stream 520 and feed oil 524 are both used, they can optionally be blended together in a vessel or line (not shown) before the emulsion step 522. Preferably, the blend stream 520 is the exclusive oil source for the emulsion 522 fed to FCIP 504, i.e., feed oil 524 is not supplied to the emulsion 522, thereby avoiding a duplication of oil blending equipment.

[0136] The emulsion step 522 emulsifies the blend stream 520 and/or feed oil 524 with chloride source material 525, iron source material 526, and water 528. The emulsion is pyrolyzed in FCIP step 504, and separated in step 530 to obtain solids 532, water 534, LIP 502, and noncondensable gas 536. Use of the blend stream 520 in this manner can facilitate pyrolysis by reducing fluid viscosities, improving emulsion stability, enhancing atomization, improving conversion, improving liquid yield of LIP 502, and improving the isomerization and/or alkylation promoting qualities of the product LIP 502, relative to the feed oil 506 and/or feed oil 524.

[0137] The second portion 509 of the LIP blend from 508 is fractionated in distillation 514. In any embodiment, the feed oil 506 may be a crude oil, preferably un-desalted crude oil, preferably where the process further comprises water washing in step 510 to desalt the second portion 509 of the LIP blend, preheating the crude in step 512, and distilling in step 514 to obtain light and heavy products 516, 518. In practice, the crude is often partially preheated to reduce viscosity, desalted, and then preheated to the distillation feed temperature. The distillation step 514 can include atmospheric and/or vacuum distillation, with which the skilled person is familiar.

[0138] Desalting 510 of the LIP blend portion 509 is facilitated due to lower salt and water content, synergistically lower viscosity and lower density, relative to the feed oil 506 by itself, and can thus be separated from water or brine more readily than the crude. Because some of the inorganic contaminants are removed by FCIP 504 from the first portion 520, the load on the desalter 510 is likewise reduced. If desired, the water 536 for the desalting 510 may come from the FCIP water 534, and/or the brine 538 may be supplied to water 528 for preparing the emulsion in 522.

[0139] Heating 512 can likewise be improved by less tendency to form coke or otherwise foul the heat transfer surfaces, allowing a higher differential temperature to be applied. To avoid this, refineries often use a series of heaters, e.g., more than a dozen, to incrementally raise the crude to the desired temperature. The LIP blend may reduce the number of heaters required.

Also, the LIP blend has an unexpectedly lower viscosity and may provide higher heat transfer coefficients. Finally, distillation 514 is improved by providing a higher yield of light products 516, a lower yield of heavy products 518, and improved quality of both the light and heavy products 516, 518. For example, the lighter products 516 tend to have an unexpectedly high proportion of the type of hydrocarbons normally obtained by isomerization and/or alkylation, which can be reflected in a lower density, lower viscosity, higher viscosity index, etc.

[0140] With reference to the embodiment according to the present invention shown in the simplified schematic flow diagram of FIG. 6, a hydrocarbon refinery process 600 is shown in which (i) a blend of the heavy products 610 from distillation 612 and a portion 602 of the product LIP 604 is treated in FCIP 606 for improved conversion, liquid yield, and LIP quality, and a reduction in the amount of coke that is formed, relative to treatment of the heavy products 610 alone and especially relative to conventional processing of the heavy products 610, e.g., in a delayed coker; and/or (ii) a portion 616 of the product LIP 604 is supplied to distillation 612 for improved yield and quality of distillates, and a reduction in the yield of the heavy products 610 and/or the amount of coke that is formed, relative to distillation of the feed oil 618 alone. [0141] Optionally, the feed oil 618 used for distillation 612 can be processed for feed to the distillation 602 in the manner as shown in FIG. 5 for the feed oil 506 in process 500 that is fed to distillation 514. In this arrangement, FIG. 5 can be seen as the front end or pretreatment of the crude supplied in a blend with the LIP to the distillation 514, 612, and FIG. 6 as a downstream processing of the heavy products 518, 610 from distillation 514, 612. In other words, processes 500 and 600 can be integrated where distillation 514 and 612 are equivalent, light products 516 and 620 are equivalent, and heavy products 518 and 610 are equivalent. The feed oil 618 is preferably a washed, preheated crude oil, e.g., the oil from heating step 512 in FIG. 5.

[0142] A first portion 602 of LIP 604 from FCIP 606 can be blended in step 608 with heavy products 610 from distillation 612. The blend, iron source material 613a, and chloride source material 613b are supplied with water 615 to the emulsion preparation step 614 for the FCIP 606.

[0143] A second portion 616 of the LIP 604 is optionally collected as a product stream and/or supplied to the distillation 612 for improved conversion of the feed oil 618 to light products 620 from the distillation, improved yield and quality of light products 620, and decreased yield of heavy products 610 and/or a reduced flow rate to resid processing 622. If desired, the LIP in stream 616 may be blended in step 508 with the feed oil 618 (corresponding to feed oil 506 in FIG. 5) upstream from the desalting 510, heating 512, and so on. When the LIP 604 derived from the heavy product 610 in FIG. 6 is supplied to the blending 508 in FIG. 5, the treatment loop through line 520 to FCIP 504 and return from LIP 502 may or may not be used, and if used, the processing rate through FCIP 504 may be reduced in size relative to the flow scheme of FIG. 3 alone.

[0144] Effluent 624 from FCIP 606 is separated to recover LIP 604, noncondensable gas 626, water 628, and solids 630. Recovered water 628 may optionally be supplied for re-use as the water 615 fed to the emulsion step 614 and/or water 528 (see FIG. 5).

[0145] With reference to FIG. 7, an apparatus 700 that may be used to prepare the feed mixture in accordance with some embodiments of the present invention comprises a mixing tank 702A equipped with an agitator 704A, which may be driven by motor 706A. If desired, redundant pumps 708A, 710A can be provided with valved lines for selective recirculation and transfer to an optional holdup tank 712 and/or directly to reactor 714. If desired, an optional second mixing train 716, including mixing tank 702B, agitator 704B, motor 706B, and pumps 708B, 710B, can be provided to facilitate batch, semi-batch or continuous feed mixture preparation. [0146] In batch operation, feed oil 718, water 720, chloride source material 721, and iron source material 722 are charged to the mixing tank 702 A (or 702B) in any order, preferably by transferring the feed oil into the mixing tank, then any solids, and then the water while maintaining agitation via agitator 704 A (or 704B) and/or providing agitation before and/or after each addition. Alternatively, the solids can be dispersed and/or dissolved in the water, e.g., in the mixing tank, and then the oil added, e.g., as a first portion to form a pre-mix emulsion to aid dispersion of the iron source material, and then as a second portion comprising the remainder of the oil. One of the pumps 708A, 710A (708B, 710B) can recirculate the mixture via valved line 711 A (71 IB) while agitating to facilitate mixing. Once the mixture has been prepared, the pumps 708A, 710A (708B, 710B) can transfer the mixture to holding tank 712 via valved line 724A (724B), or directly to FCIP reactor 714 via valved lines 726A (726B) and 728.

[0147] If desired, the feed oil 718 may be heated or mixed with a hydrocarbon diluent to reduce viscosity and facilitate pumping and mixing. The water 720 may also be optionally heated to facilitate mixing. Also, if desired, the tanks 702A, 702B, 712 and the associated lines and pumps may also be heated to keep the viscosity of the mixture low; however, the mixture in some embodiments has a lower viscosity than the feed oil 718, so it may be possible to maintain a lower temperature for the mixture or to avoid heating altogether. Furthermore, the mixing operation may be exothermic providing a source of heat in situ for the mixture. Moreover, the emulsion of the feed mixture is stable in some embodiments and so it may be prepared in advance, e.g., up to several days or more, and stored until use without phase separation, before transfer to the tank 712 and/or reactor 714. The emulsion can also be prepared off-site and pumped or trucked to the pyrolysis site. The feed mixture preparation apparatus shown in FIG. 7 may be used in or with any of the embodiments of the invention as shown in the other figures. [0148] In some embodiments, the feed mixture may be mixed using an in-line mixer(s) and/or produced in-situ within the FCIP reactor 714 by adding at least one of the feed oil, water and/or the finely divided solids directly into the FCIP reactor 714 and/or by the addition of water and/or addition of solids directly to the pyrolysis chamber, depending on the composition of the feed oil and the end use of the product LIP.

[0149] In some embodiments, the pyrolyzate vapor phase is condensable to form an oil phase lighter than the feed oil. In some embodiments the pressure in the FCIP reactor 714 is sufficiently low and the temperature sufficiently high such that the pyrolyzate exits the reactor in the vapor phase or primarily in the vapor phase, e.g. with at least 70 wt% of the recovered hydrocarbons, preferably at least 80 wt%, or at least 90 wt%, or at least 95 wt%, or at least 98 wt%, or at least 99 wt% or at least 99.9 wt%, or 100 wt% of the recovered hydrocarbon exit the reactor 146 in the vapor phase, based on the total weight of the recovered hydrocarbons. In general, the pyrolyzate effluent 148 is primarily or mostly gas phase, comprised of hydrocarbons, steam, and in the case of direct heating, additional steam or flue gases such as carbon dioxide or monoxide, nitrogen, additional steam, etc., but may entrain relatively minor amounts of liquid droplets and/or small-particle solids (fines) that may be removed by filtration, cyclonic separation and/or condensation with the recovered hydrocarbons when they are subsequently condensed to produce the catalytic pyrolysis oil product.

[0150] In an embodiment, the absolute pressure in the reactor 714 is from about 10 to 50 psia, e.g. from about 10 to 30 psia, or from about 1 atm to about 1.5 atm, or to about 1.1 atm, and the pyrolyzate vapor 148 exits from the reactor at a temperature above 425°C, e.g., above 450°C, up to about 480°C, up to about 500°C, or up to about 600°C, e.g., 450°C-500°C, 450°C- 480°C, or 500°C-600°C.

[0151] The feed mixture from line 728 may be heated in the pyrolysis chamber by hot gas 730, e.g., steam, combustion effluent or another gas at a temperature from about 300 °C or 600 °C up to about 1200°C, either in direct heat exchange relation via line 732 or indirect heat exchange relation via line 734. In practice only one arrangement is present in the apparatus 700, either direct or indirect heating. In embodiments the hot gas 730 comprises steam, or combustion gas from a fuel-rich combustion, e.g., comprising less than about 1 vol% molecular oxygen, or another effluent having a sufficiently low oxygen content to inhibit combustion in the reactor 714. In direct heating, the hot gas 730 may have a temperature from about 300 °C to about 1200 °C, and is contacted or mixed directly with the feed mixture or reaction products thereof, and the hot gas exits the FCIP reactor 714 with the pyrolyzate in effluent stream 736. In indirect heating, the hot gas 730, preferably supplied at an inlet temperature from about 600°C to about 1200°C, enters a heat exchanger 737 within the FCIP reactor 714 and cooled gas 738 is collected from an outlet of the heat exchanger. Solids 740 accumulating in the reactor 714 may be periodically or continuously removed for disposal or for recycling in the process (re-used as the finely divided solids and/or its preparation), with or without regeneration. [0152] In embodiments, the effluent 736 with the product LIP exits the FCIP reactor 714 at a temperature greater than about 425°C, or greater than about 450°C. In embodiments, the effluent 736 exits the FCIP reactor 714 at a temperature of about 600°C or below, or below about 500°C. The effluent 736 from the reactor 714 can be processed as desired, e.g., in separator 742 to remove entrained fines 744 and/or in separator 746 to recover water 748 and one or more oil fractions, e.g., LIP 750, and to exhaust non-condensable gases 752. The separator 742 can comprise a cyclone separator, a filter such as a baghouse, an electric precipitator, etc. Separator 746 can comprise condensers to recover condensate and gravity separation devices, e.g., a centrifuge or oil-water separator tank, to phase separate condensate comprising oil and water mixtures. Separator 746 can if desired optionally further include recovery of light hydrocarbons, e.g., hydrogen, methane, ethane, ethylene, propane, propylene, fuel gas, or the like, using a cryogenic process, membrane separators, and so on.

[0153] In embodiments, the FCIP reactor 714 comprises a turbulent environment, and may contain a bed of particulate inert solids (see FIG. 9), which may comprise silica, alumina, sand, or a combination thereof, and/or may include nonvolatile residues from previously treated mixtures such as ash, coke, and/or heavy hydrocarbons (i.e., having 40 carbons or more). These residues may collect and/or may be continuously or periodically removed from the FCIP reactor 714. In embodiments, the feed mixture in line 728 is fed to FCIP reactor 714 at a point below a bed, thus fluidizing the bed, and/or the feed mixture may enter just over the bed, e.g., downwardly directed such as onto the bed or on an impingement plate (fixed or partially fluidized bed) from which the more volatile compounds rise immediately and the less volatile compounds are converted to more volatile compounds in the bed.

[0154] In embodiments, the combustion gases utilized as the hot gas 730 in any of the processes disclosed herein, especially in the direct heating embodiments, are sub- stoichiometric with respect to oxygen (oxygen lean/fuel rich) such that the concentration of molecular oxygen Ch in the reactor is less than about 1 vol%, or less than 0.1 vol%, or the combustion gas is essentially free of molecular oxygen. Accordingly, in embodiments, the pyrolysis reactor 714 comprises a reducing atmosphere.

[0155] With reference to FIG. 8, a process 800 according to some embodiments of the present invention comprises a mixer and/or mixing tank 802 to combine feed oil 804, water 806, chloride source 807, and iron source 808 into an emulsion as described herein (cf. discussion of FIG. 7). The emulsion is transferred via pump 810 to FCIP reactor 812. An oxygen source 814 such as air, oxygen or oxygen-enriched air is combined with fuel 816 in combustion burner 818 to supply combustion effluent in line 820 to the reactor 812, as described herein (cf. discussion of FIG. 7). Control system 821 is provided to control the operating conditions of the FCIP reactor 812, e.g., by manipulation or adjustment of the feed rate(s) and/or combustion rates to maintain the pyrolysis zone at a temperature, pressure and residence time to form an LIP vapor phase. In the case of indirect heating, cold gas 822 is recovered; otherwise the combustion gases are mixed with the steam and LIP vapors and recovered in effluent line 824. Solids 826 may be recovered from the reactor 812 continuously or periodically.

[0156] The effluent from line 824 is optionally processed in fines removal unit 828, to separate fines 830, optionally including any liquid droplets or other solids, and the remaining vapor can optionally be supplied directly to an oil or heavy oil reservoir recovery process (see Fig. 11 of US 2016/0160131 Al), or after conditioning to remove any undesirable components, supplement any additional components needed, compress to injection pressure, heat to the desired injection temperature, and/or cool to recover waste heat. Where the iron source material is unsupported, the fines removal can be eliminated or designed for substantially reduced fines content.

[0157] The remaining vapor can be cooled in exchanger 834 and hydrocarbon condensate (LIP I) 836 recovered from separator 838. The process temperature in the exchanger 834 and separator 838 is preferably above the water dew point so that the condensate 836 is essentially free of water, e.g., less than 1 wt%. The vapors from separator 838 are then cooled in exchanger 840 and condensate 842 recovered from separator 844. The process temperature in the exchanger 840 and separator 844 is preferably below the water dew point so that the condensate 842 is a mixture of water and oil, which can be further separated in separator 846, which can be a centrifuge or gravity settling tank, for example, to obtain oil product (LIP II) 848 and water 850. The overhead vapor from the separator 844 can be exhausted and/or used as a fuel gas, or it can optionally be further processed in exchanger 852 for cooling and separated in separator 854 into non-condensable gases 856 and or product 858 comprised of one or more streams of hydrogen, methane, ethane, ethylene, propane, propylene, carbon dioxide, fuel gas, including combinations thereof. The separator 854 can be any one or suitable combination of a cryogenic separator, membrane separator, fractionator, solvent extraction, pressure swing absorption, or the like.

[0158] With reference to FIG. 9, a process 900 comprises a reactor 902 that is directly heated by combustion gases or steam supplied from burner 904 and combustion chamber or boiler906 through duct 908, which can direct the combustion effluent/steam through distributor 908a located to fluidize the solids 909. Feed mixture 910 can be prepared, for example, as described above (cf. discussion of FIGs. 7-8). The feed mixture 910 is supplied to nozzle 912 and forms a preferably conical spray pattern 914 in the reactor 902.

[0159] The nozzle 912 is directed downwardly and can be positioned near the upper end of the reactor, e.g., 1/3 of the way down from the top of the reactor toward the bottom. The nozzle 912 is preferably designed and positioned so that the spray pattern 914 avoids excessive impingement on the inside surfaces of the reactor 902 that can lead to caking and/or buildup of solids on the walls. For example, the nozzle 912 can provide a conical spray pattern. The feed mixture 910 is thus introduced countercurrently with respect to the flue gas or steam from combustion chamber or boiler 906 to promote mixing and rapid heating to facilitate the conversion and volatilization of hydrocarbons.

[0160] The pyrolyzate vapor phase exits the reactor 902 together with the combustion gas and steam from the feed mixture water into duct 916. The upward flow rate of the gases in the reactor 902 in some embodiments is sufficiently low to avoid excessive entrainment of solid particulates. The solid particulates can thus fall to the bottom of the reactor 902 and can be periodically and/or continuously withdrawn, e.g., via rotary valve 918, for disposal and/or regeneration and recycle to the slurry preparation. Regeneration can be effected in some embodiments by contacting the solids with an oxygen containing gas at high temperature to promote combustion of hydrocarbon residue and coke from the particles. In any embodiment, regeneration can be in situ in reactor 902, e.g., by supplying oxidant gas into the solids bed 909 for combustion of coke.

[0161] The gases from the reactor 902 in some embodiments are optionally passed into cyclone 920 for removal of fines. Where an unsupported iron source material is used, for example, the cyclone 920 may not be needed and/or can be designed for removal of substantially reduced fines content. Fines, when present, can be periodically and/or continuously withdrawn from the cyclone 920, e.g., via rotary valve 926. The solids-lean gases in some embodiments are then passed through condensers 922 and 924. The first condenser 922 preferably condenses hydrocarbons, which have a relatively higher boiling point than water, at a temperature above the water dew point so that the oil 928 (LIP I) has a low water content, e.g., essentially free of water so that water separation is not needed. The second condenser 924 preferably condenses the hydrocarbons and water which may be processed, if desired, in separator 932 to separate an oil phase 934 (LIP II) from a water phase 936, e.g., by gravity settling, centrifuge, or the like. The recovered water in this and any of the other embodiments illustrated herein can, if desired, be recycled for preparation of the feed mixture to the FCIP reactor (cf. FIGs. 1, 4-8), the desalting 510 (FIG. 5), and so on. Non-condensed exhaust gases 938 are recovered overhead from the condenser 924.

EXAMPLES

[0163] Example 1A: Preparation of iron solids: Preferred finely divided solids according to the present invention were prepared by mixing with constant stirring 1 part by weight 100 mesh hydrogen reduced iron shavings with 1 part by weight aqua regia (1 part by weight nitric acid, 3 parts by weight hydrochloric acid, 2 parts by weight water). The aqua regia was added in three aliquots (1 part each, i.e., 1/3, 1/3, 1/3), and the temperature increased to 95°C. The material dried considerably, leaving wet solids. The oxidized iron solids were dried in an oven at 130°C, and ground to pass a 100 mesh screen. The oxidized iron solids had a reddish black or dark violet color.

[0164] The oxidized iron solids were analyzed by wet chemistry by sequential digestion in hot water, followed by digestion of the water-insoluble solids in 20 wt% HCl(aq), and recovery of the insoluble material which was not further analyzed. Initially, a 5 g sample of the oxidized iron solids was placed in 150 ml of 100°C water, and the water-insoluble solids remaining were recovered and weighed. The amount digested in the water was surprisingly only 1.4488 g, or 28.98 wt%. The filtrate was diluted to 1 L and the solute was found by spectrophotometry to contain 11.32 wt% total Fe consisting of 3.24 wt% Fe(II) and 8.08 wt% Fe(III), 32.79 wt% chloride, 3.52 wt% nitrite, and 1.17 wt% nitrate. The water-soluble fraction was thus determined to be mostly chloride and nitrite salts with some nitrate salts.

[0165] The water-insoluble fraction was then digested in 150 ml of 20% HC1 in water, and 3.478 g went into solution, or 69.56 wt% of the initial oxidized iron sample. The acid soluble fraction was found to contain 62.23 wt% total Fe consisting of 7.04 wt% Fe(II) and 55.19 Fe(III), 51.18 wt% nitrate, and 0.2587 wt% nitrite. The acid soluble fraction was thus found to contain mostly ferric oxides and/or nitrates, with some ferrous iron and a small amount of nitrite. From a relatively small proportion of ferrous iron seen in the acid soluble fraction, it was inferred that little or no elemental iron was present. The acid insoluble fraction was just 1.46 wt% of the original sample, and appeared from its red color to be Fe(III) oxide, hematite. The wet chemistry data are summarized in Table 1.

[0166] Example IB: Preparation of iron solids with 2X aqua regia : The finely divided solids were prepared as in Example 1A except 1 part by weight 100 mesh hydrogen reduced iron shavings was mixed with 2 parts by weight aqua regia comprising 1 parts by weight nitric acid, 3 parts by weight hydrochloric acid, and 2 parts by weight water. Following the reaction between 25 kg of the iron and 50 kg of the aqua regia, the reaction mass weighed 58.5 kg. After drying at 130 °C, the acidified iron product weighed 36 kg and had a reddish black color. XRD analysis showed the presence of hematite, magnetite, and beta-ferric oxide hydroxide. SEM analysis showed 65.5 wt% Fe; 23.0 wt% O; 8.08 wt% Cl; 1.97 wt% Cu; and less than 1 wt% of Cr, Si, Al, and Sr. The acidified iron product or one similar to it was used in the following examples 2A-3B.

[0167] Example 2A: Flash Chemical Ionizing Pyrolysis Tests on Texistepec Crude Oil-LIP Blend in a Lab Reactor with High-Chloride Iron Additive : These flash chemical ionizing pyrolysis (FCIP) tests used an externally heated lab scale reactor equipped with a condenser and a bag for non-condensable gases. The feed emulsion was pulsed into the reactor using a spray nozzle at a rate to keep the reactor within a range of about +/- 10 °C of the average, 460 °C. [0168] Texistepec crude oil was pretreated by heating to a temperature of 150 °C for 1 h to remove water and sediment that settled out. The pretreated crude oil (s.g. 1.221 g/cm³, viscosity 5,676,000 cP at 50 °C, Flash point 200 °C, boiling point 280 °C, Conradson carbon 18.2%) was blended at 70 °C with an LIP obtained from previous FCIP at a weight ratio of crude: LIP of 90:10 to obtain a blend having s.g. of 1.1 g/cm³, viscosity 57,900 cP at 50 °C, and Conradson carbon 14.4%. The blend contained 9.96 wt% soluble inorganics.

[0169] The feed emulsion was prepared by first mixing the high-chloride iron additive of Example IB (168 g per 100 kg oil) with 1 M NaCl (876 g NaCl per 100 kg oil) and water (total water 15 kg/100 kg oil) using a high speed blender at ambient temperature, and then mixing the water-NaCl-Fe additive mixture with the oil blend at 70 °C. The resulting feed emulsion had density of 1.1 g/cm³ and viscosity at 50 °C of 34,980 cP. The feed emulsion had the composition shown in Table 2:

[0170] FCIP of the feed emulsion yielded two immiscible oil layers, a light oil layer (67.5 wt%, hydrocarbons basis) and a heavy oil layer (17.5 wt%, hydrocarbons basis), non-condensable gas (12.8 wt%, hydrocarbons basis), and coke (2.2 wt%, hydrocarbons basis). These surprising results indicate that 97.8 wt% of the Texistepec crude can be recovered as high quality oil and light hydrocarbons. Also recovered were 82.6 wt% of the water (feed basis) and 69.5 wt% of the inorganic solids (total feed basis). The product mix is listed in Table 3: TABLE 3. FCIP PRODUCT MIX, EXAMPLE 2A

Notes: 1 - based on hydrocarbons in feed emulsion; 2 - based on water in feed emulsion; 3 - based on total feed soluble inorganics, NaCl, and Fe compound [0171] The recovered oils were markedly improved with lower density, lower viscosities, lower flash points, lower boiling points, and lower pour points. A comparison of properties with the pretreated Texistepec crude oil and the LIP blend is listed in Table 4:

[0172] It is seen from Tables 3 and 4 that the LIP-1 and LIP-2 are recovered from the FPIC of the Texistepec crude oil in surprisingly high yield. Moreover, LIP-1 and LIP-2 have unexpectedly improved properties indicative of astonishingly high quality as reflected in low densities, low viscosities, low flash points, low boiling points, low pour points and low Conradson carbon contents. The low conversion to coke in the FCIP and the low Conradson carbon contents in the LIP products indicate that thermal processing, e.g., distillation, will result in very little coke make.

[0173] Example 2B: Flash Chemical Ionizing Pyrolysis Tests on Texistepec Crude Oil-LIP Blend in a Lab Reactor with Supported Iron Additive: These flash chemical ionizing pyrolysis (FCIP) tests used an externally heated lab scale reactor equipped with a condenser and a bag for non-condensable gases as in Example 2A. The feed emulsion was pulsed into the reactor using a spray nozzle at a rate to keep the reactor within a range of about +/- 10 °C of the average, 470 °C, similar to Example 2A.

[0174] As in Example 2 A, Texistepec crude oil was pretreated by heating to a temperature of 150°C for 1 hto remove water and sediment that settled out. The pretreated crude oil (s.g. 1.221 g/cm³, viscosity 5,676,000 cP at 50 °C, Flash point 200 °C, boiling point 280 °C, Conradson carbon 18.2%) was blended at 70 °C with an LIP obtained from previous FCIP, at a weight ratio of crude:LIP of 90: 10 to obtain a blend having s.g. of 1.1 g/cm³, viscosity 57,900 cP at 50 °C, and Conradson carbon 14.4%. The blend contained 10.1 wt% soluble inorganics.

[0175] The feed emulsion was prepared by first mixing the supported iron additive of Example 1C (5 kg per 100 kg oil, 5.4 wt% acidified iron, 4.5 wt% NaCl) with the oil blend at 70 °C using a high speed blender, and then adding the water (15 kg per 100 kg oil). The resulting feed emulsion had density of 1.1 g/cm³ and viscosity at 50 °C of 32,000 cP. The feed emulsion had the composition shown in Table 5:

TABLE 5. FCIP FEED EMULSION, EXAMPLE 2B

Hydrocarbons 76.52

Soluble inorganics _ 8 58

Total crude oil _ 85 1

Water 11.50

Total 100.00 [0176] FCIP of the feed emulsion yielded two immiscible oil layers, a light oil layer (61.9 wt%, hydrocarbons feed basis) and a heavy oil layer (27.7 wt%, hydrocarbons feed basis), non condensable gas (5.1 wt%, hydrocarbons basis), and coke (5.3 wt%, hydrocarbons basis). These results indicate that 94.7 wt% of the Texistepec crude can be recovered as high quality oil and light hydrocarbons. Also recovered were 93 wt% of the water (feed basis) and 100.2 wt% of the inorganic solids (total feed basis). Compared to Example 2A, Example 2B using the supported catalyst produced less LIP-3 and more coke. The product mix is listed in Table 6: TABLE 6. FCIP PRODUCT MIX, EXAMPLE 2B

Component _ Wt%

LIP-3, light oil phase yield¹ 61.9

LIP-4, heavier oil phase yield¹ _ 27.7

Total oil yield¹ _ 896

Gas yield¹ 5.1

Coke yield¹ _ 5 3

Total hydrocarbon yield¹ _ 100.0

Water yield² _ 93 0

Solid inorganics yield³_ 100.2

Notes: 1 - based on hydrocarbons in feed emulsion; 2 - based on water in feed emulsion; 3 - based on total feed soluble inorganics, NaCl, and Fe compound [0177] It is thus seen that the coke make is greater and the LIP-3 yield is lower when the bentonite was present. Moreover, the solid inorganics yield included spent bentonite, which would require solids removal equipment.

[0178] The recovered oils were markedly improved with lower density, lower viscosities, lower flash points, lower boiling points, and lower pour points. However, the values for the LIP-3 were not as good compared to the LIP-1 obtained from Example 2A which was run bentonite-free. A comparison of properties with the pretreated Texistepec crude oil and the LIP blend is listed in Table 7:

[0179] It is seen from Tables 6 and 7 that the LIP-3 and LIP-4 are recovered from the FCIP of the Texistepec crude oil in surprisingly high yield using the bentonite-loaded iron compound and NaCl. Moreover, LIP-3 and LIP-4 have unexpectedly improved properties indicative of high quality as reflected in low densities, low viscosities, low flash points, low boiling points, low pour points and low Conradson carbon contents. The low conversion to coke in the FCIP and the low Conradson carbon contents in the LIP products indicate that thermal processing, e.g., distillation, will result in very little coke make. It is further seen from a comparison of the properties that the LIP-1 of Example 2 A prepared without bentonite has a higher proportion of lower molecular weight hydrocarbons than the LIP-3 prepared using bentonite, indicating a higher degree of conversion, as reflected in the lower pour point of LIP-1. It is further seen that the LIP-4 prepared with bentonite has a higher proportion of light fractions and higher quality compared to LIP-3 if the goal is to produce gasoline ranges of hydrocarbons.

[0180] Example 3A: Flash Chemical Ionizing Pyrolysis on Maya Crude Oil in a Lab Reactor with High-Chloride Iron Additive: These flash chemical ionizing pyrolysis (FCIP) tests used the same lab scale reactor as Example 2A. The feed emulsion was pulsed into the reactor using a spray nozzle at a rate to keep the reactor within a range of about +/- 10 °C of the average, 500 °C.

[0181] A 22 °API Maya crude oil was used having s.g. 0.92 g/cm³, viscosity 450 cP at 50 °C, flash point 133 °C, boiling point 155 °C, Conradson carbon 12%, and 1 wt% inorganic solids content. The feed emulsion was prepared by first mixing the high-chloride iron additive of Example IB (168 g per 100 kg crude) with 0.25 M NaCl (219 g NaCl per 100 kg crude) and water (total water 15 kg/100 kg crude) using a high speed blender at ambient temperature, and then mixing the water-NaCl-Fe additive mixture with the crude oil. The feed emulsion had the composition shown in Table 8:

These surprising results indicate that 99.3 wt% of the Maya crude can be recovered as high quality oil and light hydrocarbons. Also recovered were 81.8 wt% of the water (feed basis) and 97.0 wt% of the inorganic solids (total feed basis). The product mix is listed in Table 9: TABLE 9. FCIP PRODUCT MIX, EXAMPLE 3A

[0184] It is seen from Tables 9 and 10 that the LIP-5 was recovered from the FPIC of the Maya crude oil in surprisingly high yield. Moreover, the LIP-5 had unexpectedly improved properties indicative of astonishingly high quality as reflected in low density, low viscosity, low flash point, low boiling point, low pour point and low Conradson carbon content. The low conversion to coke in the FCIP and the low Conradson carbon content in the LIP-5 product indicate that thermal processing, e.g., FCIP and distillation, will result in very little coke make. [0185] Example 3B: Flash Chemical Ionizing Pyrolysis on Maya Crude Oil in a Lab Reactor with Supported Iron Additive: These flash chemical ionizing pyrolysis (FCIP) tests used the same lab scale reactor and Maya crude oil as Example 3A. The feed emulsion was pulsed into the reactor using a spray nozzle at a rate to keep the reactor within a range of about +/- 10 °C of the average, 510 °C. [0186] The feed emulsion was prepared by first mixing the supported iron additive of Example

1C (5 kg per 100 kg oil, 5.4 wt% acidified iron, 4.5 wt% NaCl) with the oil blend at 70 °C using a high speed blender, and then adding the water (15 kg per 100 kg oil). The resulting feed emulsion had density of 0.96 g/cm³ and viscosity at 50 °C of 270 cP. The feed emulsion had the composition shown in Table 11:

These surprising results indicate that 98 wt% of the Maya crude can be recovered as high quality oil and light hydrocarbons. Also recovered were 84.2 wt% of the water (feed basis) and 99.7 wt% of the inorganic solids (total feed basis). The product mix is listed in Table 12: TABLE 12. FCIP PRODUCT MIX, EXAMPLE 3B

[0190] It is further seen that the LIP-5 of Example 3 A prepared without bentonite is even better than the LIP-6 of Example 3B prepared with bentonite in that the LIP-5 has a lower density and comparable Conradson carbon content. There appear to be no untoward effects from eliminating the bentonite but using the same or similar amounts of the iron compound and NaCl.

[0191] Example 4A: Flash Chemical Ionizing Pyrolysis on Texistepec Crude Oil in a Lab Reactor with Mixed Iron Additive: This flash chemical ionizing pyrolysis (FCIP) test used commercially obtained iron compounds hematite (Fe203, industrial grade), magnetite (Fe304, industrial grade), and prepared b-FeOOH, and FeOCl.

[0192] b-FeOOH was prepared by adding 100 mL of a 5.4 M NaOH solution (20.147 g NaOH/100 mL of distilled water) dropwise over an equal volume of a solution of FeCh/itLO (53.8 g in 100 mL of distilled water) at a temperature of 40 °C ± 2 °C and with constant agitation. The mixture was then placed in an oven at 100 °C for 6 hours. After this time the reaction was stopped by rapid cooling in cold water. The product (15.45 g) was collected by filtration, washed with distilled water, dried at room temperature and crushed to obtain a fine powder.

[0193] FeOCl was prepared in a 500 mL ball flask to which was added 7.00 g of Fe203 and 8.20 g of FeCb · 6H2O. The flask was purged with argon and heated to 370 °C for 30 minutes to carry out the reaction. After cooling, the product (11.16 g) was crushed to obtain a fine powder.

[0194] The iron compounds were screened to remove +100 mesh particles, using only the fines that passed through the sieve. The iron compound used in this example was a mixture of equal parts by weight of Fe203, Fe304, b-FeOOH, and FeOCl.

[0195] Texistepec crude oil was pretreated by heating to a temperature of 150 °C for 1 h to remove water and sediment that settled out. The pretreated crude oil had s.g. 1.2 g/cm³, viscosity 833,800 cP at 50 °C, Flash point 228 °C, boiling point 314 °C, Conradson carbon 15%. The feed emulsion was prepared by first mixing the blended iron additive (240 g per 100 kg oil) with 1 M NaCl (220 g NaCl per 100 kg oil) and water (total water 15 kg/100 kg oil) using a high speed blender at ambient temperature, and then mixing the water-NaCl-Fe additive mixture with the pretreated Texistepec crude at 70 °C. The resulting feed emulsion had density of 1.2 g/cm³ and viscosity at 50 °C of 199,400 cP. The flash chemical ionizing pyrolysis (FCIP) used the same lab scale reactor as Example 2A. The feed emulsion was pulsed into the reactor using a spray nozzle at a rate to keep the reactor within a range of about +/- 5 °C of the average, 530 °C.

[0196] FCIP of the feed emulsion yielded liquid oil (85.8 wt%, hydrocarbons basis), non condensable gas (1.6 wt%, hydrocarbons basis), and coke (12.7 wt%, hydrocarbons basis). These surprising results indicate that 97.8 wt% of the Texistepec crude can be recovered as high quality oil and light hydrocarbons. Also recovered were 75.2 wt% of the water (feed basis) and 95.6 wt% of the inorganic solids (total feed basis). The product mix is listed in Table 14: TABLE 14. FCIP PRODUCT MIX, EXAMPLE 4A

These would be further improved by using the Texistepec in a blend with the LIP-7 in the feed emulsion.
