US Patent:

8168686, May 1, 2012

Filed:

Dec 22, 2010

Appl. No.:

12/976763

Inventors:

Randy Blevins - West Des Moines IA, US
Joshua B. Pearson - Englewood CO, US
Harold A. Wright - Longmont CO, US

Assignee:

Rentech, Inc. - Los Angeles CA

International Classification:

C07C 27/00

US Classification:

518705, 518700, 518704

Abstract:

A method and system for reforming a carbonaceous feedstock comprising the steps, reforming the feedstock produce a first synthesis gas, subjecting a portion of the first synthesis gas to catalytic conversion, separating from the synthesis gas conversion product at least one byproduct, and utilizing at least a portion of the at least one byproduct during reforming of additional carbonaceous material. In certain instances, the method and system may be used to produce a liquid fuel.

C07C 27/06

US Classification:

518704, 252373

Abstract:

A method of producing synthesis gas by mixing a carbonaceous feed comprising at least one carbonaceous material with superheated steam to produce a reformer feedstock and reforming the reformer feedstock to produce a first synthesis gas comprising hydrogen and carbon monoxide by introducing the reformer feedstock into a plurality of coiled tubes within a reformer at a reformer temperature and a reformer pressure at which at least a portion of the reformer feedstock is converted to synthesis gas.

Appl. No.:

13/246451

Inventors:

Randy BLEVINS - West Des Moines IA, US
Joshua B. PEARSON - Englewood CO, US
Harold A. WRIGHT - Longmont CO, US

International Classification:

B01J 19/00

US Classification:

422187

Abstract:

A system for the production of conversion products from synthesis gas, the system including a mixing apparatus configured for mixing steam with at least one carbonaceous material to produce a reformer feedstock; a reformer configured to produce, from the reformer feedstock, a reformer product comprising synthesis gas comprising hydrogen and carbon monoxide from the reformer feedstock; a synthesis gas conversion apparatus configured to catalytically convert at least a portion of the synthesis gas in the reformer product into synthesis gas conversion product and to separate from the synthesis gas conversion product a tailgas comprising at least one gas selected from the group consisting of carbon monoxide, carbon dioxide, hydrogen and methane; and one or more recycle lines fluidly connecting the synthesis gas conversion apparatus with the mixing apparatus, the reformer, or both.

Assignee:

RENTECH, INC. - Los Angeles CA

International Classification:

B01J 7/00
B01F 13/06

US Classification:

422162, 366139

Abstract:

A system for the production of synthesis gas, the system including a mixing apparatus configured for combining steam with at least one carbonaceous material to produce a reformer feedstock; and a reformer comprising a cylindrical vessel containing a plurality of coiled tubes, wherein each of the plurality of coiled tubes has a vertical height in the range of from about 40 feet 12.2 m) to about 100 feet (30.5 m) and a coil length that is at least four times the vertical height; at least one burner configured to combust a fuel and provide heat to maintain the reformer at a reformer temperature; at least one outlet for reformer product comprising synthesis gas; and at least one outlet for flue gas produced via combustion of fuel in the burners. A suitable mixing apparatus is also provided.
