Methods For Producing Syngas

View page
US Patent:
8153027, Apr 10, 2012
Filed:
Jul 1, 2008
Appl. No.:
12/166167
Inventors:
Robert E. Klepper - Arvada CO, US
Arie Geertsema - Westminster CO, US
Shakeel H. Tirmizi - Matawa NJ, US
Francis M. Ferraro - Westminster CO, US
Assignee:
Range Fuels, Inc. - Denver CO
International Classification:
C01B 3/22
US Classification:
252373
Abstract:
This invention features methods and apparatus for producing syngas from any carbon-containing feed material. In some embodiments, a substoichiometric amount of oxygen is used to enhance the formation of syngas. In various embodiments, both oxygen and steam are added during the conversion of the feed material into syngas. The syngas can be converted to alcohols, such as ethanol, or to other products.

US Patent:
20090014689, Jan 15, 2009
Filed:
Jul 1, 2008
Appl. No.:
12/166194
Inventors:
Robert E. Klepper - Arvada CO, US
Francis M. Ferraro - Westminster CO, US
Shakeel H. Tirmizi - Matawa NJ, US
Arie Geertsema - Westminster CO, US
Jerrod Hohman - Superior CO, US
Ronald C. Stites - Brighton CO, US
Assignee:
Range Fuels, Inc. - Broomfield CO
International Classification:
C01B 3/38
B01J 19/00
B01D 1/00
US Classification:
252373, 159 431, 422198, 159 471
Abstract:
This invention features methods and apparatus for producing syngas from any carbon-containing feed material. In some embodiments, a substoichiometric amount of oxygen is used to enhance the formation of syngas. In various embodiments, both oxygen and steam are added during the conversion of the feed material into syngas. Some variations employ eductors for facilitating flow of solid and gas phases in the processes of the invention. The syngas can be converted to alcohols, such as ethanol, or to other products.

US Patent:
20090018371, Jan 15, 2009
Filed:
Jul 1, 2008
Appl. No.:
12/166203
Inventors:
Robert E. KLEPPER - Arvada CO, US
Arie GEERTSEMA - Westminster CO, US
Heinz Juergen ROBOTA - Arvada CO, US
Ronald C. STITES - Brighton CO, US
Richard RIDLEY - Loveland CO, US
Assignee:
Range Fuels, Inc. - Broomfield CO
International Classification:
C07C 29/32
US Classification:
5689022
Abstract:
Methods and apparatus for producing alcohols from syngas are disclosed herein. In some variations, syngas is catalytically converted to methanol in a first reaction zone, and residual syngas from the first reaction zone is then catalytically converted to ethanol in a second reaction zone. Also, in some variations, syngas is catalytically converted to methanol in high yield in a first reaction zone, and the methanol is then converted (optionally, with additional syngas) to ethanol in a second reaction zone.

US Patent:
20090093555, Apr 9, 2009
Filed:
Dec 16, 2008
Appl. No.:
12/336138
Inventors:
Ronald C. STITES - Brighton CO, US
Jerrod HOHMAN - Superior CO, US
Robert E. KLEPPER - Arvada CO, US
Arie GEERTSEMA - Westminster CO, US
Shakeel H. TIRMIZI - Matawan NJ, US

Assignee:
Range Fuels, Inc. - Broomfield CO
International Classification:
C07C 27/00
US Classification:
518702
Abstract:
This invention features methods and apparatus for producing syngas from any carbon-containing feed material. In some embodiments, a substoichiometric amount of oxygen is used to enhance the formation of syngas. In various embodiments, a catalyst is derived from the ash content of the feed material, and this catalyst is used to enhance syngas formation. The syngas can be converted to alcohols, such as ethanol, or to other products.
