Definitions

  • This invention relates generally to a method for the production of aromatics from renewable sources. More specifically, the preferred embodiments related to converting fat- or other lipid-containing oils derived from biomass, such as oil from naturally-occurring non-vascular photosynthetic organisms and/or from genetically modified non-vascular photosynthetic organisms; canola oil and other oils derived from vegetables such as corn, soybean, sunflower, and sorghum; and/or oils from other plant matter, seeds, fungi, bacteria, and other organisms both living and recently living.
  • biomass such as oil from naturally-occurring non-vascular photosynthetic organisms and/or from genetically modified non-vascular photosynthetic organisms
  • canola oil and other oils derived from vegetables such as corn, soybean, sunflower, and sorghum
  • oils from other plant matter, seeds, fungi, bacteria, and other organisms both living and recently living such as corn, soybean, sunflower, and sorghum
  • Aromatics particularly benzene, toluene, ethylbenzene, and the xylenes (ortho, meta, and para isomers), which are commonly referred to as “BTEX” or more simply “BTX,” are extremely useful chemicals in the petrochemical industry. They represent the building blocks for materials such as polystyrene, styrene-butadiene rubber, polyethylene terephthalate, polyester, phthalic anhydride, solvents, polyurethane, benzoic acid, and numerous other components. Conventionally, BTEX is obtained for the petrochemical industry by separation and processing of fossil-fuel petroleum fractions, for example, in catalytic reforming or cracking refinery process units, followed by BTX recovery units.
  • the patent literature describes refinery schemes proposed for processing biomass to produce transportation fuels, such as gasoline, jet, and diesel. See, for example, North Carolina State University, WO 2008/103204, published 28 Aug. 2008, and entitled “Process for Convention of Biomass to Fuel”. See also, Aravanis, et al., Publication US2009/0126260, published 21 May 2009, entitled “Methods of Refining Hydrocarbon feedstocks”, and McCall, et al., Publication US2009/0158637, published 25 Jun. 2009, and entitled “Production of Aviation Fuel from Biorenewable Feedstocks”. The patent literature focuses, however, on transportation fuel production from renewable feedstocks, rather than aromatics production for the petrochemical industry.
  • the patent literature focuses on renewable feedstocks that are comprised mainly of triglycerides, for example, plant oils such as canola, soy bean, camelina and jatropha oils, and animal fats such as beef and lamb tallow and chicken fat, which are approximately 100% triglycerides.
  • plant oils such as canola, soy bean, camelina and jatropha oils
  • animal fats such as beef and lamb tallow and chicken fat, which are approximately 100% triglycerides.
  • the invention comprises methods, catalyst, and/or equipment for converting one or more renewable oils to aromatics, for example, for use in the petrochemical industry and/or for blending components or additives for fuels.
  • the invented processing methods comprise contacting one or more renewable oils with a catalytically-active form of gallium, for example, a catalyst comprising a catalytically-active form of gallium (also called “gallium-modified” catalyst herein).
  • a catalytically-active form of gallium also called “gallium-modified” catalyst herein.
  • Such gallium-modified catalyst may comprise a zeolite or other solid that retains gallium in a catalytically-active form, for example, as gallium cations.
  • the invention may comprise products made by said methods.
  • Said one or more renewable oils may be obtained from biomass, which is defined as a mass, or a material including a substantial amount of said mass, that is alive or that has been alive within the last 50 years.
  • biomass which is defined as a mass, or a material including a substantial amount of said mass, that is alive or that has been alive within the last 50 years.
  • examples of such renewable oils are canola oil and other lipids-based bio-oils derived from vegetables such as corn, soybean, sunflower, and sorghum; oil from naturally-occurring non-vascular photosynthetic organisms and/or from genetically modified non-vascular photosynthetic organisms, and/or oil from other plant matter, seeds, fungi, bacteria, and other organisms.
  • the bio-oils may be extracted from their respective biomass by conventional techniques.
  • the term non-vascular photosynthetic organism includes, but is not limited to, macroalgae, microalgae and cyanobacteria (blue-green algae).
  • said one or more renewable oils feature a H/C mole ratio of greater than 1.5 (typically 1.7-2.1), and oxygen content of about 1 to about 35 wt-% (typically 5-15 wt %).
  • the renewable oil(s) comprise large amounts of fatty acids or fatty acid esters, including free fatty acids and/or glycerol esters of fatty acids such as monoglycerides, diglycerides, and/or triglycerides.
  • the H/C mole ratio, oxygen content, and relative amounts of free fatty acids and glycerol esters in said one or more renewable oils may depend on the source of the renewable oil and/or on the techniques of extraction from the biomass and/or pre-processing prior to contact with the gallium-modified catalyst, for example.
  • the fatty acid moieties may range, for example, from about 4 to about 30 carbon atoms, but typically 10 to 25 carbon atoms, and even more typically, 16 to 22 carbon atoms. Most commonly, the fatty acid moieties are saturated or contain 1, 2 or 3 double bonds.
  • the renewable oil(s) contain at least some triglycerides that are glycerol esters of C16-C22 carboxylic acids and therefore may comprise C50+ compounds, however, many of the diglycerides and/or triglycerides in the renewable oil(s) decompose to their C-16-C-22 components upon heating to elevated temperature.
  • the renewable oil(s) may also comprise other materials such as carotenoids, hydrocarbons, phosphatides, simple fatty acids and their esters, terpenes, sterols, fatty alcohols, tocopherols, polyisoprene, carbohydrates and/or proteins.
  • some embodiments of the invention are expected to produce large amounts of hydrogen, and this hydrogen may be fed to hydrogen-consuming units in the refinery, for example, a hydrotreater or hydrocracker.
  • some embodiments of the invention may be used both for “green” BTEX production and for “green” hydrogen production.
  • the gallium-retaining solid is a shape-selective material, and more typically, the solid is a zeolitic material wherein at least some of the cation-exchange centers are populated with gallium.
  • the gallium-retaining solid(s) is/are gallium-doped version(s) of one or more zeolite-alumina matrix catalysts with pore sizes having 10 oxygen atoms in the pore mouth, for example, ZSM-5, ZSM-11, ZSM-23, MCM-70, SSZ-44, SSZ-58, SSZ-35, and ZSM-22.
  • the inventors have discovered that aromatics-production from the renewable oils is enhanced at higher gallium levels, with one level being Ga occupying at least 90% of the cation sites and the protons or other cations previously at those cation sites having been replaced by Ga.
  • An exemplary gallium level is 90-100% of the cation sites being replaced by Ga, which is called “1.0 Ga/framework-Al” herein.
  • Catalysts in certain embodiments of the invention may have gallium loadings above 1.0 Ga/framework-Al, that is, gallium present in an amount above that equal to 100% cation replacement.
  • extraframework Ga would exist, that is, Ga over and above the amount corresponding to 1 Ga/framework-Al and residing in zeolitic pores or on the exterior of the zeolite crystalline particles.
  • zeolite frameworks may contain other metals, for example, gallium, boron, iron, phosphorous, germanium, indium, etc. Zeolite frameworks containing other metals may be suitable for producing gallium-modified catalyst, for example, for loading with gallium in cationic form for use as catalysts in certain embodiments of the invention.
  • the solid may be adapted to retain gallium by processes known to those of skill in the catalyst arts, for example, incipient wetness impregnation of zeolite with a gallium-composition dissolved in water.
  • Methods for producing gallium-doped catalyst are also described in U.S. Pat. Nos. 4,727,206, 4,746,763, 4,761,511, and 5,149,679, the teachings of which are incorporated herein by this reference.
  • Said one or more renewable oils may comprise “whole crude oil”, that is, the entire oil extract from biomass, and/or one or more fractions of said whole crude oil.
  • Said one or more renewable oils may comprise whole crude oil(s)/fraction(s) that have been pre-processed before being fed to the gallium-catalyst process.
  • pre-processing in this context may include degumming, RBD (Refining, Bleaching, and Deodorizing, which is known in the art), thermal processing, hydrotreating, and/or other processes that deoxygenate or otherwise upgrade the renewable oil to some extent before being fed to the process comprising use of gallium-modified catalyst.
  • said one or more renewable oils may be co-processed (“co-fed”) with other oils, such as fossil petroleum oils/fractions, to the aromatics-production processes of this invention.
  • said existing, revamped, or new units for certain embodiments of the invention may include those that are the same or similar to fluidized catalytic cracking (FCC) units (for example, see FIG. 23 ), UOP CCRTM CyclarTM units (for example, see FIG. 24 ), a UOP CCR PlatformerTM naphtha reformer fixed-bed reactor(s), or other fixed-bed reactor units, all of which originated as fossil petroleum technology.
  • FCC units fluidized catalytic cracking
  • UOP CCRTM CyclarTM units for example, see FIG. 24
  • UOP CCR PlatformerTM naphtha reformer fixed-bed reactor(s) or other fixed-bed reactor units, all of which originated as fossil petroleum technology.

  • Example III Conclusions from Example III, and Comparison of Example I (Canola Oil) and Example III (Algae Oil)
  • HZSM-5 Adding gallium to HZSM-5 increases BTEX yield and gasoline yield for algae oil cracking at 400° C. GaZSM-5 also produced significantly more hydrogen than HZSM-5, which is consistent with an increased aromatics production.
  • This Example describes the catalytic cracking of gas oil (from Conoco Phillips) over HZSM-5 and Ga-doped ZSM-5 (GaZSM-5) at 400 degrees C., for comparison to canola oil and algae oil results from Examples I and III.
  • the goal of this work was to compare the formation of aromatics between these two catalysts, specifically benzene, toluene, and xylenes (BTEX), for fuel blending, or for use as feedstocks in the chemical industry. It was observed that Ga/ZSM-5 produced more BTEX and less paraffins (especially propane) compared to HZSM-5 gas oil cracking at the same reaction temperature. However, the boost in BTEX yield when Ga was added to the catalyst was much greater for the renewable oils (algae and canola oils) and the overall gasoline yields are also greater for the renewable oils.
  • GaZSM-5 was made according to the method reported in Example I, but the only gallium loading level that was used in this Example corresponded to 1.0 Ga/framework-Al in the zeolite (Ga/ZSM-5).
  • the base ZSM-5 material was used in its fully protonated form (H-ZSM-5). Because H-ZSM-5 gave the highest BTEX yield at 400 degrees C. for algae oil feedstock in Example III, the gas oil cracking experiments of this Example were also done at this temperature.
  • the Ga/ZSM-5 catalyst was activated at 500 degrees C. under a 100 ml/min stream of 30% hydrogen in nitrogen for at least 1 hour. This activation process is known to accelerate the ion-exchange of Ga cations for protons in the zeolite.

  • Reactor temperature was set to 400° C.
  • the total mass balance for each run was performed based upon the difference between grams of reactant fed and product collected.
  • Product collected is separated into three parts: 1) the gaseous product which, is continuously measured by the micro-GC system, 2) a condensed liquid product which, was collected from the reactor's effluent in a trap and glass adapter at 0° C., and 3) the coke which, is left on the catalyst and simply measured by mass difference between the fresh and used catalyst.
  • Table 11 gives the overall mass balances obtained from gas oil cracking over Ga/ZSM-5 and H-ZSM-5. It can be seen clearly Ga/ZSM-5 produced more liquid and less gas compared to H-ZSM-5. The detailed product analysis is discussed below.
  • FIG. 9 shows the gas phase products produced during cracking of gas oil. It is clear that the C1-C3 paraffin yield decreased with doping of the zeolite with gallium, and the amount of propane decreased by a factor of three. It is also clear that a higher amount of hydrogen product was present in the run utilizing Ga/ZSM-5 compared to the run utilizing H-ZSM-5. The increased hydrogen product with the gallium-doped zeolite correlated well with the previous work involving algae (Example III) and canola oil (Example I) cracking over Ga/ZSM-5, showing that an increased amount of BTEX is formed through the addition of Ga.
  • a simulated distillation of the Conoco Phillips gas oil is compared to the simulated distillation of algae oil in FIG. 11 .

  • Gasoline yields of each of the products from gas oil, canola oil, and algae oil over the H-ZSM-5 and GaZSM-5 catalysts were also obtained via simulated distillation, and these results are included in the last line of Table 12. It may be noted that, when the feedstock was gas oil, addition of Ga had virtually no effect on the gasoline yields, which were about 48% in both cases. However, for the renewable oils, a significant effect of the addition of Ga was noted.
  • FIG. 12 also shows how much different the products from the various feedstocks were.
  • the renewable oils produced much lighter liquid products than the gas oil produced.
  • the algae oil and canola oil feedstocks were heavier than gas oil, a much greater disparity in the overall reduction in boiling point distribution of the feedstock resulted when the renewable oils were the feedstocks.

  • FIG. 13 compares the conversion (percent of the feed converted to distillate and to lighter components such as gasoline, plus coke) at a range of catalyst-to-oil ratios (C/O) for the algae oil feed and the reference petroleum VGO feed.
  • C/O catalyst-to-oil ratios
  • FIG. 14 shows that the coke yield for the algae oil feed is significantly higher than for the VGO. This is important because commercial-scale FCC units operate in such a way that the heat balance drives the conversion of feeds to lower levels when they have high coke yields. Consequently, the algae oil feed of this Example is expected to exhibit much lower conversion than VGO in commercial units due to its high coke yield.

  • Certain methods of this Example may comprise, consist essentially of, or consist of method steps a-e above.
  • Algae oils/fractions may range from very little to all of the feedstock for the processing unit(s) in steps b and e above, for example, from about 0.1 volume percent up to 100 volume percent of the liquid feedstock being fed to said processing unit(s).
  • the hydrotreated oil derived from the crude algae oil will be a minor portion of the entire FCC feedstock (for example, 1-20 wt % or 5-10 wt %) and the gallium-cation catalyst will be only a portion of the entire FCC catalyst loading (for example, 1-20 wt % or 5-10 wt %).
  • Certain crude algae oils may be thermally treated prior to being fed to FCC operations such as described in Example VI. Because of the complex composition and/or the high molecular weight materials of said certain algae oils extracted from biomass, thermal treatment prior to processing in any catalytic unit may be effective in reducing one or more of the following characteristics: oxygen content and/or other heteroatom content, metals content, high molecular weight content, 1000 degree F.+ content, 1020 degree F.+ content, boiling range/distribution, viscosity, and/or catalyst poisons and/or coke-on-catalyst precursors.
  • catalyst deactivation due to poisoning of catalyst active sites (such as acidic sites being poisoned by basic nitrogen compounds) and/or producing coke-on-catalyst.
  • thermal treatment will reduce most or all of these characteristics.
  • thermal treatment of whole crude algae oil obtained from biomass is expected to mitigate catalyst deactivation and/or coke-on-catalyst production caused by the crude algae oil, thereby extending catalyst life in such units as a hydrotreater, or improving heat balances in continuous catalyst regeneration systems such as FCC units.
  • the thermal treatment methods of this Example may be used in conjunction with hydrotreating over large-pore catalysts (see Example VI) to improve catalyst lives and/or heat balances in downstream units.
  • a thermal treatment method may be applied to certain crude algae oils, the method comprising:
  • End products from the above process may include one or more of BTX plant feedstock, gasoline, kerosene, jet fuel, diesel fuel, or lube base stock, for example.
  • Certain methods of this Example may comprise, consist essentially of, or consist of method steps a-g above.
  • Algae oils/fractions may range from very little to all of the feedstock for the processing unit(s) in steps b, d, and g above, for example, from about 0.1 volume percent up to 100 volume percent of the liquid feedstock being fed to said processing unit(s).
  • the hydrotreated oil derived from the crude algae oil will be only a portion of the entire FCC feedstock (for example, 1-20 wt % or 5-10 wt %) and the gallium-modified catalyst will be only a portion of the entire FCC catalyst loading (for example, 1-20 wt % or 5-10 wt %).
  • the above steps of this Example may be modified so that only a portion of the crude algae oil, such as a heavy fraction, is thermally-treated, but both the thermally-treated portion (minus any solids/coke and gasses formed in the thermal treating) and the un-thermally-treated portion of the crude algae oil are combined for hydrotreating and subsequent fluid catalytic cracking.
  • Certain embodiments may comprise “spiking” relatively small amounts of renewable oil(s) into a refinery unit previously operating on non-renewable feedstocks, and providing at least some gallium-cation catalyst in the unit.
  • relatively small amounts may be meant that the renewable oil may be added as 1-20 wt % (more typically 5-10 wt %) of a unit's feedstock, with gallium-cation catalyst being added as 1-20 wt % (more typically 5-10 wt %) of the unit's catalyst.
  • Such a “spiking” approach may be particularly effective in an fluidized catalyst process unit, for example, an FCC unit, as further described below.
  • conventional FCC feedstock is heated and sprayed into the base of a riser (a vertical or upward-sloped pipe), where the pre-heated feedstock contacts fluidized zeolite catalyst typically at about 950 to 1030 degree F. (approximately 510 to 555 degree C.).
  • the hot catalyst vaporizes the feedstock and catalyzes the cracking reactions that break down the high molecular weight hydrocarbons into lighter components including LPG (liquid petroleum gas such as C3-C4 olefins), and acyclic or cyclic hydrocarbons (C5-C12).
  • LPG liquid petroleum gas such as C3-C4 olefins
  • C5-C12 acyclic or cyclic hydrocarbons
  • the catalyst-hydrocarbon mixture flows upward through the riser for just a few seconds (for example, 2-4 seconds) and then the mixture is separated via cyclones.
  • the catalyst-free hydrocarbons are routed to a fractionation column for separating shorter hydrocarbon products (for example, C3-C12 hydrocarbons) from the heavier fuels.
  • the shorter hydrocarbons many of which are suitable as gasoline products, are more volatile than the heavier fuels.
  • the heavier fuels include diesels and jet fuels that fractionally distill between approximately 200 degree C. and 350 degree C. at atmospheric pressure.
  • the cracking catalyst is “spent” by reactions that deposit coke on the catalyst and greatly reduce activity and selectivity.
  • the process of coke formation is important to the overall process because it increases the H/C (hydrogen to carbon) ratio of the gaseous products to a range more suitable for gasoline.
  • the spent catalyst is disengaged from the cracked hydrocarbon vapors and sent to a stripper where it is contacted with steam to remove hydrocarbons remaining in the catalyst pores.
  • the spent catalyst then flows into a fluidized-bed regenerator where air (or in some cases air plus oxygen) is used to burn off the coke to restore catalyst activity and also provide the necessary heat for the next reaction cycle.
  • the regenerated catalyst then flows to the base of the riser, repeating the cycle.
  • Catalyst and additives are typically added to FCC units using systems each comprising a bin and a lock hopper.
  • the minimum catalyst addition rates are determined by the physical attrition and loss of the FCC catalyst as fines that escape capture in the cyclone systems in both the regenerator flue gas and the oil that goes from the riser/reactor to the main fractionators. Thus, catalyst fines show up in the slurry oil that is also sometimes called decant oil or DCO.
  • Catalyst/additives are added to the FCC at rates above this physical loss depending on the activity for conversion and yields that are desired in the FCC. For example, if a higher activity of catalyst/additive is required, fresh catalyst/additive will be added at a higher rate.
  • a refinery unit may be purpose-built for processing solely renewable oil(s) over catalyst that is only, or substantially, a gallium-cation catalyst, to produce excellent yields of BTEX and/or gasoline and hydrogen.
  • One such purpose-built unit may be similar to a UOP CyclarTM unit, which comprises a moving bed of said gallium-cation catalyst and a coke-burning regeneration section, as schematically portrayed in FIG. 24 .
  • a purpose-built fixed-bed reactor unit may be effective. Regeneration in both units may be limited to solely coke-burning followed by reduction during normal operation in the reactor.
  • Both units would be optimized with respect to temperature, pressure, flowrates, gallium loading, etc., as would be understood by those of skill in the art.
  • These purpose-built units would preferably operate on 80-100 wt %, and more preferably 90-100 wt % renewable oil(s), for example, algae oil, with the catalyst being 80-100 wt %, or more preferably, 90-100 wt %, gallium-cation-retaining catalyst.
