  • Patent number: 7378452
    Abstract: A method for separating and filtering solid particles from a hydrocarbon slurry liquid includes two or more filter sections in fluid communication with the hydrocarbon slurry. At least one filter section is comprised of one or more filter elements having a mean pore size of less than 10 microns, and at least one other section is comprised of one or more filter elements having a mean pore size of 10 microns or greater. The small pore filter (less than 10 microns) will exclude all or substantially all of the smaller catalyst fines produced by catalyst particle attrition. The liquid product removed from the small pore filters will be substantially free of particulates. The large pore filters (10 microns or greater) will exclude larger catalyst particles, but will allow the smaller fines to pass. The liquid product removed from the large pore filters will contain the fines generated from catalyst particle attrition.

  • Patent number: 7375143
    Abstract: Embodiments of the invention relate to processes and apparatus for the washing and recovery of metal-containing catalyst solids in a form suitable for reclamation. More specifically, a catalyst recovery process comprises removing an organic residue with a washing medium from a metal-containing catalyst solids, recovering washed solids, and treating the washed solids under oxidative conditions to form non-reactive solids. The treatment oxidative conditions may be effective to convert the metal(s) into an oxide form and/or may facilitate the removal of remaining organic residue from the washed solids. The treatment of the washed solids may comprise calcination. In some embodiments, the metal-containing catalyst solids may be recovered from a slurry stream, and the process further comprises passing the slurry stream though a separation unit to obtain a catalyst-enriched retentate slurry.

  • Patent number: 7375142
    Abstract: A carbonaceous feedstock to alcohol conversion process in which carbon dioxide and a portion of the hydrogen produced are removed from the syngas stream issuing from a feedstock reformer, to yield a reduced hydrogen, carbon monoxide and methane syngas stream. The hydrogen and the carbon dioxide are passed through a Fischer Tropsch reactor which is catalyzed to favor the production of methanol. The methanol produced in the Fischer-Tropsch reactor is passed with the reduced hydrogen syngas through a second Fischer-Tropsch reactor which is catalyzed to favor the production of ethanol. Also disclosed, without limitation, are a unique catalyst, a method for controlling the content of the syngas formed in the feedstock reformer, and a feedstock handling system.

  • Patent number: 7365102
    Abstract: In a process for forming a methane-enriched fuel, a hydrocarbon feedstock that includes hydrocarbons having molecular weights greater than that of methane (CH4) is mixed with an oxidizable gaseous reactant that includes water (H2O) and is free of molecular oxygen (O2). The mixture, which has a H2O/total hydrocarbon (H2O/C) ratio of less than about 1, is heated to an elevated temperature in the presence of a catalyst to form a methane-enriched pre-reformate product. At least a portion of the feedstock hydrocarbons having molecular weights greater than that of methane is converted to methane (CH4) in the process.

    Abstract: A process and apparatus for producing a synthesis gas for use as a gaseous fuel or as feed into a Fischer-Tropsch reactor to produce a liquid fuel in a substantially self-sustaining process. A slurry of particles of carbonaceous material in water, and hydrogen from an internal source, are fed into a hydro-gasification reactor under conditions whereby methane rich producer gases are generated and fed into a steam pyrolytic reformer under conditions whereby synthesis gas comprising hydrogen and carbon monoxide are generated. A portion of the hydrogen generated by the steam pyrolytic reformer is fed through a hydrogen purification filter into the hydro-gasification reactor, the hydrogen therefrom constituting the hydrogen from an internal source. The remaining synthesis gas generated by the steam pyrolytic reformer is either used as fuel for a gaseous fueled engine to produce electricity and/or process heat or is fed into a Fischer-Tropsch or similar reactor under conditions whereby a liquid fuel is produced.
