摘要： An integrated process for producing liquid fuel and lubricating base oil from Fischer-Tropsch derived products which comprises (a) recovering separately from a Fischer-Tropsch synthesis reactor a Fischer-Tropsch wax and condensate; (b) hydroprocessing the wax and recovering a waxy intermediate and a hydrogen-rich normally, liquid fraction; (c) mixing the condensate and at least part of the hydrogen-rich normally liquid fraction to form a Fischer-Tropsch condensate mixture; (d) hydrotreating the condensate mixture and recovering a Fischer-Tropsch condensate product; (e) recovering from the condensate product a liquid fuel; (f) separately dewaxing the waxy intermediate and recovering a base oil; (g) hydrofinishing the base oil; (h) recovering from the hydrofinishing zone a stabilized base oil and a hydrogen-rich gas; and (i) recycling the hydrogen-rich gas to the wax hydroprocessing zone wherein the total pressure in the hydrofinishing zone is at least as high as the total pressure in the wax hydroprocessing zone.

摘要： An integrated process for producing Fischer-Tropsch derived products boiling in the range of liquid fuel and lubricating base oil comprises (a) recovering from a Fischer-Tropsch synthesis a Fischer-Tropsch wax 2 and a Fischer-Tropsch condensate 78; (b) hydroprocessing the wax in zone 6 and recovering a waxy intermediate 12 and a hydrogen-rich normally liquid fraction 72; (c) mixing the Fischer-Tropsch condensate 78 from step (a) and at least part of the hydrogen-rich normally liquid fraction 72 from step (b) to form a Fischer-Tropsch condensate mixture 74; (d) hydrotreating the Fischer-Tropsch condensate mixture in zone 76 and recovering a Fischer-Tropsch condensate product 78; (e) recovering from the Fischer-Tropsch condensate product a Fischer-Tropsch derived hydrocarbon boiling within the range of liquid fuel 96,98; (f) dewaxing the waxy intermediate from step (b) in a catalytic dewaxing zone 26 and recovering a base oil 32; (g) hydrofinishing 30 the base oil from step (f); (h) recovering from the hydrofinishing zone 30 a UV stabilized lubricating base oil 56 and a hydrogen-rich gas 4; and (i) recycling the hydrogen-rich gas from step (h) to the wax hydroprocessing zone of step (b) and wherein the total pressure in the hydrofinishing zone is at least as high as the total pressure in the wax hydroprocessing zone. The process has a common higher pressure H2 loop for the hydrotreatment and hydrofinishing steps, and a lower pressure H2 loop for the dewaxing step.

摘要： A flexible once-through process for hydroprocessing heavy oil feedstock is disclosed. The process employs a plurality of contacting zones and at least a separation zone to convert at least a portion of the heavy oil feedstock to lower boiling hydrocarbons, forming upgraded products. The contacting zones operate under hydrocracking conditions, employing a slurry catalyst which comprises an active metal catalyst having an average particle size of at least 1 micron in a hydrocarbon oil diluent, at a concentration of greater than 500 wppm of active metal catalyst to heavy oil feedstock. The plurality of contacting zones and separation zones are configured in a permutable fashion allowing the once-through process to be flexible operating in various modes: a sequential mode; a parallel mode; a combination of parallel and sequential mode; all online; some online and some on stand-by; some online and some off-line; a parallel mode with the effluent stream from the contacting zone being sent to at least a separation zone in series with the contacting zone; a parallel mode with the effluent stream from the contacting zone being combined with an effluent stream from at least another contacting zone and sent to the separation zone; and combinations thereof. In one embodiment, the effluent from a contacting zone is sent to the next contacting zone in series for further upgrade, with the next contacting zone having a pressure drop of at most 100 psi, with the pressure drop is not due to a pressure reducing device as in the prior art. In one embodiment, at least an additive material selected from inhibitor additives, anti-foam agents, stabilizers, metal scavengers, metal contaminant removers, metal passivators, and sacrificial materials, in an amount of less than 1 wt. % of the heavy oil feedstock, is added to at least one of the contacting zones.

摘要： Applicants have developed a new residuum full hydroconversion slurry reactor system that allows the catalyst, unconverted oil, hydrogen, and converted oil to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is separated internally, within one of more of the reactors, to separate only the converted oil and hydrogen into a vapor product while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor as a liquid product. A portion of the unconverted oil is then converted to lower boiling point hydrocarbons in the next reactor, once again creating a mixture of unconverted oil, hydrogen, converted oil, and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. The oil may alternately be partially converted, leaving a concentrated catalyst in unconverted oil which can be recycled directly to the first reactor.

摘要： A new residuum full hydroconversion slurry reactor system has been developed that allows the catalyst, unconverted oil and converted oil 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 converted oil while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor where a portion of the unconverted oil is converted to lower boiling point hydrocarbons, once again creating a mixture of unconverted oil, converted oil, 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. Fully converted oil can be subsequently hydrofinished for the nearly complete removal of hetoroatoms such as sulfur and nitrogen.
