Patent number: 7431831Abstract: A new residuum full hydroconversion slurry reactor system has been developed that allows the catalyst, unconverted oil, products and hydrogen to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is partially separated in between the reactors to remove only the products and hydrogen while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor. In the next reactor, a portion of the unconverted oil is converted to lower boiling point hydrocarbons, once again creating a mixture of unconverted oil, products, hydrogen and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. The oil may alternately be partially converted, leaving a highly concentrated catalyst in unconverted oil which can be recycled directly to the first reactor. The slurry reactor system is, in this invention, preceded by an in-line pretreating step, such as hydrotreating or deasphalting.Type: GrantFiled: December 16, 2005Date of Patent: October 7, 2008Assignee: Chevron U.S.A.

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.Type: GrantFiled: October 16, 1987Date of Patent: March 28, 1989Assignee: HRI, Inc.Inventors: Joseph B. McLean, Alfred G. Comolli, James B. MacArthur

Patent number: 4750991Abstract: A method for hydrogenating a solvent-refined coal, comprising:(a) hydrogenating coal in the presence of a hydrocarbon solvent and an iron catalyst;(b) obtaining a solvent-refined coal material therefrom, which has a boiling point of at least 400.degree. under atmospheric pressure conditions;(c) removing preasphaltenes from said solvent-refined coal material to obtain a substantially preasphaltene free solvent-refined coal; and(d) hydrogenating the solvent-refined coal in a fixed bed under hydrogen pressure.Type: GrantFiled: July 3, 1985Date of Patent: June 14, 1988Assignees: Mitsubishi Chemical Industries, Ltd., Kabushiki Kaisha Kobe Seiko Sho, Idemitsu Kosan Company Limited, Asia Oil Company Limited, Nippon Brown Coal Liquefaction Co., Ltd.Inventors: Yoichi Kageyama, Hironori Kageyama, Jun Imai, Yukio Nakako

Patent number: 4740294Abstract: A method for sequentially co-processing heavy hydrocarbon materials and carbonaceous materials comprising first subjecting the heavy hydrocarbon material in the presence of a disposable metal catalyst to produce and separate therefrom a first distillate stream and a first non-distillable effluent stream containing the disposable metal catalyst. The first non-distillable effluent stream then is mixed with the carbonaceous material and the mixture subjected to liquefaction conditions in the presence of said disposable metal catalyst. The liquefaction product then is subjected through the use of sequential fractionation and critical solvent extraction processing steps to separate and recover various heavy hydrocarbon and carbonaceous-derived light hydrocarbon liquid products therefrom.Type: GrantFiled: September 25, 1984Date of Patent: April 26, 1988Assignee: Kerr-McGee CorporationInventor: Donald E. Rhodes

Patent number: 4661237Abstract: A process for thermally cracking carbonaceous substances, such as coal, is described, comprising: rapidly heating the carbonaceous substance to 500.degree. to 950.degree. C. in an atmosphere consisting essentially of hydrogen gas at a pressure of 35 to 250 kg/cm.sup.2 (gauge pressure) in the presence of at least one compound selected from the group consisting of halides, sulfates, nitrates, phosphates, carbonates, hydroxides, and oxides of Group VIII metal elements of the Periodic Table. The process increases the cracking of the carbonaceous substances and accelerates the conversion of the carbonaceous substances into gas and liquid products, greatly increasing the yields of the gasoline fraction and light oils.Type: GrantFiled: March 29, 1983Date of Patent: April 28, 1987Assignee: Asahi Kasei Kogyo Kabushiki KaishaInventors: Muneaki Kimura, Tadashi Kai

Patent number: 4602991Abstract: A liquefaction process for coal or lignite is set forth. In the preferred and illustrated embodiment, coal or lignite is ground to a suitable particle size and placed in a reactor vessel. The reactor vessel is located within a pressure vessel. Pressure in the vessel is reduced to about 10.sup.-2 torr.Heat is applied. One procedure is to convert the carbon (in the coal or lignite) at an elevated temperature (600.degree.-900.degree. F.) in the presence of hydrogen (at pressures as high as 2,000 psi) into a hydrocarbon mix; depressurization avoids making various oxides and nitrides, and also can be optionally carried out in the presence of iron or iron ore in particulate form acting as a catalyst.Type: GrantFiled: October 17, 1983Date of Patent: July 29, 1986Inventor: Prabhakar Kulkarni
