摘要： A dispersed fine-sized anion-modified and phosphorus-promoted iron-oxide slurry catalyst having high surface area exceeding 100 m.sup.2 /gm and high catalytic activity, and which is useful for hydrogenation and hydroconversion reactions for carbonaceous feed materials is disclosed. The catalyst is synthesized by rapid aqueous precipitation from saturated salt solutions such as ferric sulfate and ferric alum, and is promoted with phosphorus. The iron-based catalysts are modified during their preparation with anionic sulfate (SO.sub.4.sup.2-). The resulting catalyst has primary particle size smaller than about 50 Angstrom units, and may be used in a preferred wet cake or gel form which can be easily mixed with a carbonaceous feed material such as coal, heavy petroleum fractions, mixed waste plastics, or mixtures thereof. Alternatively, the catalyst can be dried and/or calcined so as to be in a fine dry particulate form suitable for adding to the feed material. The invention includes methods for making the catalyst and processes for using the catalyst for hydroprocessing of carbonaceous feed materials to produce desirable low-boiling hydrocarbon liquid products.

摘要： A multi-stage catalytic hydrogenation and hydroconversion process for heavy hydrocarbon feed materials such as coal, heavy petroleum fractions, and plastic waste materials. In the process, the feedstock is reacted in a first-stage, back-mixed catalytic reactor with a highly dispersed iron-based catalyst having a powder, gel or liquid form. The reactor effluent is pressure-reduced, vapors and light distillate fractions are removed overhead, and the heavier liquid fraction is fed to a second stage back-mixed catalytic reactor. The first and second stage catalytic reactors are operated at 700-850° F. temperature, 1000-3500 psig hydrogen partial pressure and 20-80 lb./hr per ft3 reactor space velocity. The vapor and light distillates liquid fractions removed from both the first and second stage reactor effluent streams are combined and passed to an in-line, fixed-bed catalytic hydrotreater for heteroatom removal and for producing high quality naphtha and mid-distillate or a full-range distillate product. The remaining separator bottoms liquid fractions are distilled at successive atmospheric and vacuum pressures, low and intermediate-boiling hydrocarbon liquid products are withdrawn, and heavier distillate fractions are recycled and further upgraded to provide additional low-boiling hydrocarbon liquid products. This catalytic multistage hydrogenation process provides improved flexibility for hydroprocessing the various carbonaceous feedstocks and adjusting to desired product structures and for improved economy of operations.

摘要： A highly dispersed iron-based ionic liquid or liquid-gel catalyst which may be anion-modified and metals-promoted has high catalytic activity, and is useful for hydrocracking/hydrogenation reactions for carbonaceous feed materials. The catalyst is produced by aqueous precipitation from saturated iron salt solutions such as ferric sulfate and ferric alum, and may be modified during preparation with anionic sulfate (SO.sub.4.sup.2-) and promoted with small percentages of at least one active metal such as cobalt, molybdenum, palladium, platinum, nickel, or tungsten or mixtures thereof. The resulting catalyst may be used in a preferred ionic liquid form or in a liquid-gel form, and either fluidic form can be easily mixed and reacted with carbonaceous feed materials such as coal, heavy petroleum fractions, mixed plastic waste, or mixtures thereof. The invention includes methods for making the ionic liquid or liquid-gel catalyst, and processes for using the fluidic catalysts for hydroprocessing the carbonaceous feed materials to produce desirable low-boiling hydrocarbon liquid products.

摘要： A process for two-stage catalytic hydrogenation and liquefaction of coal to produce increased yields of low-boiling hydrocarbon liquid and gas products. In the process, the particulate coal is slurried with a process-derived liquid solvent and fed at temperature below about 650.degree. F. into a first stage catalytic reaction zone operated at conditions which promote controlled rate liquefaction of the coal, while simultaneously hydrogenating the hydrocarbon recycle oils at conditions favoring hydrogenation reactions. The first stage reactor is maintained at 650.degree.-800.degree. F. temperature, 1000-4000 psig hydrogen partial pressure, and 10-60 lb coal/hr/ft.sup.3 reactor space velocity. The partially hydrogenated material from the first stage reaction zone is passed directly to the close-coupled second stage catalytic reaction zone maintained at a temperature at least about 25.degree. F. higher than for the first stage reactor and within a range of 750.degree.-875.degree. F. temperature for further hydrogenation and thermal hydroconversion reactions. By this process, the coal feed is successively catalytically hydrogenated and hydroconverted at selected conditions, which results in significantly increased yields of desirable low-boiling hydrocarbon liquid products and minimal production of undesirable residuum and unconverted coal and hydrocarbon gases, with use of less energy to obtain the low molecular weight products, while catalyst life is substantially increased.

摘要： A coal hydrogenation and liquefaction process in which particulate coal feed is pressurized to an intermediate pressure of at least 500 psig and slurried with CO.sub.2 liquid to provide a flowable coal/CO.sub.2 slurry feedstream, which is further pressurized to at least 1000 psig and fed into a catalytic reactor. The coal particle size is 50-375 mesh (U.S. Sieve Series) and provides 50-80 W % coal in the coal/CO.sub.2 slurry feedstream. Catalytic reaction conditions are maintained at 650.degree.-850.degree. F. temperature, 1000-4000 psig hydrogen partial pressure and coal feed rate of 10-100 lb coal/hr ft.sup.3 reactor volume to produce hydrocarbon gas and liquid products. The hydrogen and CO.sub.2 are recovered from the reactor effluent gaseous fraction, hydrogen is recycled to the catalytic reactor, and CO.sub.2 is liquefied and recycled to the coal slurrying step. If desired, two catalytic reaction stages close coupled together in series relation can be used. The process advantageously minimizes the recycle and processing of excess hydrocarbon liquid previously needed for slurrying the coal feed to the reactor(s).

摘要： A multi-stage catalytic process for hydrogenation and liquefaction of coal using ebullated-bed catalytic reactors to produce low-boiling hydrocarbon liquid products, in which used catalyst is removed from a lower temperature first stage reactor operating at temperature not exceeding about 800.degree. F. and cascaded forward to a higher temperature second stage reactor for further use therein. Reaction conditions in the first stage reactor are preferably 700.degree.-800.degree. F. temperature, 1000-4000 psig hydrogen partial pressure, and a coal feed rate of 10-90 lb coal/hr per ft.sup.3 catalyst settled volume in the reactor. Useful higher temperature or second stage reaction conditions are 750.degree.-850.degree. F. temperature, and 1000-4000 psig hydrogen partial pressure. The used catalyst withdrawn from the lower temperature of first stage reactor has a catalyst age of 300-3000 lb coal proceses/lb fresh catalyst, and is transferred forward to the higher temperature second stage reactor for further use to catalyst age of 1000-6000 lb coal processed per lb fresh catalyst. If desired, a higher temperature third catalytic reactor can be provided and used catalyst from the second stage reactor cascaded forward into the third reactor for further use therein. Useful catalysts include metal oxides of cobalt, iron, molybdenum, nickel, tin, or tungsten deposited on a base of alumina, magnesia, silica, or titania, with cobalt moly and nickel moly on alumina catalyst being preferred. This process advantageously requires a smaller quantity of fresh catalyst per ton of coal processed to produce the low-boiling hydrocarbon liquid products.
摘要翻译：一种用于使用沸腾床催化反应器来加氢和液化煤的多阶段催化方法，用于生产低沸点烃液体产物，其中使用的催化剂在不超过约800°F的温度下操作的较低温度的第一级反应器中除去。并级联到较高温度的第二级反应器中以便在其中进一步使用。第一级反应器中的反应条件优选为700-800°F的温度，1000-4000psig的氢分压，以及在反应器中的10-90lb煤/小时/ ft 3催化剂沉降体积的煤进料速率。有用的较高温度或第二阶段反应条件为750-850°F的温度和1000-4000 psig的氢分压。从第一阶段反应器的较低温度取出的使用催化剂的催化剂年龄为300-3000磅煤/ lb新鲜催化剂，并转移到较高温度的第二阶段反应器中进一步用于催化剂年龄为1000-6000磅每磅新鲜催化剂加工煤。如果需要，可以提供更高温度的第三催化反应器，并将来自第二级反应器的催化剂用于向前进入第三反应器以供其进一步使用。有用的催化剂包括沉积在氧化铝，氧化镁，二氧化硅或二氧化钛的基体上的钴，铁，钼，镍，锡或钨的金属氧化物，优选钴钼和镍钼氧化铝催化剂。该方法有利地需要每吨处理生产低沸点烃液体产品的较少量的新鲜催化剂。
