    Abstract: A process for catalytic two-stage hydrogenation and liquefaction of coal with selective extinction recycle of all heavy liquid fractions boiling above a distillation cut point of about 600.degree.-750.degree. F. to produce increased yields of low-boiling hydrocarbon liquid and gas products. In the process, the particulate coal feed is slurried with a process-derived liquid solvent normally boiling above about 650.degree. F. and fed 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. The first stage reactor is maintained at 710.degree.-800.degree. F. temperature, 1000-4000 psig hydrogen partial pressure, and 10-90 lb/hr per ft.sup.3 catalyst space velocity. Partially hydrogenated material withdrawn from the first stage reaction zone is passed directly to the second stage catalytic reaction zone maintained at 760.degree.-860.degree. F. temperature for further hydrogenation and hydroconversion reactions. A 600.degree.-750.degree. F..sup.+ fraction containing 0-20 W % unreacted coal and ash solids is recycled to the coal slurrying step. If desired, the cut point lower boiling fraction can be further catalytically hydrotreated. By this process, the coal feed is successively catalytically hydrogenated and hydroconverted at selected conditions, to provide significantly increased yields of desirable low-boiling hydrocarbon liquid products and minimal production of hydrocarbon gases, and no net production of undesirable heavy oils and residuum materials.

    Abstract: This invention utilizes a novel method and set of operating conditions to efficiently and economically process a potentially very fouling hydrocarbon feedstock. A multi-stage catalytic process for the upgrading of coal pyrolysis oils is developed. Coal Pyrolysis Oils are highly aromatic, olefinic, unstable, contain objectionable sulfur, nitrogen, and oxygen contaminants, and may contain coal solids which will plug fixed-bed reactors. The pyrolysis oil is fed with hydrogen to a multi-stage ebullated-bed hydrotreater and hydrocracker containing a hydrogenation or hydrocracking catalyst to first stabilize the feed at low temperature and is then fed to downstream reactor(s) at higher temperatures to further treat and hydrocrack the pyrolysis oils to a more valuable syncrude or to finished distillate products. The relatively high heat of reaction is used to provide the energy necessary to increase the temperature of the subsequent stage thus eliminating the need for additional external heat input. A refined heavy oil product stream is recycled to the fresh feed to minimize feedstock fouling of heat exchangers and feed heaters.

    Abstract: A process for two-stage catalytic co-processing of coal and heavy petroleum hydrocarbon liquid fractions to produce increased yields of low-boiling hydrocarbon liquid and gas products. In the process, the particulate coal is slurried with a petroleum residuum and optionally with a process-derived hydrocarbon liquid solvent and fed into a first stage catalytic reaction zone operated at relatively mild conditions which promote controlled rate liquefaction of the coal while simultaneously hydrogenating the petroleum and 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 10-100 lb/hr/ft.sup.3 space velocity for the total coal and oil feed. From the first stage reaction zone, the partially hydrogenated effluent material is passed directly to the close-coupled second stage catalytic reaction zone maintained at more severe conditions of 750.degree.-900.degree. F. temperature for further catalytic; and hydrogenation and hydroconversion reactions. By this process, the blended coal and petroleum feed materials are successively catalytically hydrogenated and hydroconverted at the 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, while catalyst life is substantially increased.

    Abstract: A multi-stage catalytic process for the direct liquefaction of coal is utilized with a hydrotreater to first liquefy and subsequently treat the product in one integrated process. A fresh hydrogenation catalyst is used to reduce heteroatoms (S, N) from coal liquids in the downstream hydrotreater. This catalyst is then cascaded and re-used in the direct coal liquefaction process, first in the low temperature Stage 1, and then re-used in the high temperature Stage 2. Coal liquid products have very low contaminants and can be readily used to produce gasoline and diesel fuel. Catalyst requirements are substantially lowered utilizing this novel process.

    Abstract: The invention described herein relates to a novel process that eliminates the need for post combustion CO2 capture from fired heaters (at atmospheric pressure and in dilute phase) in a petroleum refinery to achieve environmental targets by capturing CO2 in a centralized facility and providing fuel gas low in carbon to the fired heaters. It combines the pre-combustion capture of carbon dioxide with production of a hydrogen fuel source within a refinery to drastically reduce the carbon dioxide emissions of the plant. The hydrogen fuel is utilized for the process fired heaters and the fuel quality (carbon content) can be set to meet the refinery's emissions objectives. Moreover, the carbon dioxide captured can be sequestered and/or utilized for enhanced oil recovery (EOR).

    Abstract: 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.
