Synthesis Gas Production Method And Reactor

US Patent:
2007029, Dec 20, 2007
Filed:
Jun 19, 2006
Appl. No.:
11/454884
Inventors:
John William Hemmings - Katy TX, US
Leo Bonnell - Houston TX, US
Earl T. Robinson - Mentor OH, US
International Classification:
C01B 3/26, B01J 12/00
US Classification:
423651, 422168
Abstract:
A method of producing a synthesis gas from a hydrocarbon containing gaseous feed in which the hydrocarbon containing gaseous feed is reacted in an autothermal reactor having separated reaction stages in which partial oxidation and steam methane reforming reactions occur. Each of the reaction stages has alternating separation zones and catalytic reaction zones. Oxygen separated by oxygen ion transport in the separation zone supports the partial oxidation reactions occurring in the catalytic reaction zones. Reactants are separately metered to the reaction stages to control temperatures within the reaction stages so that use of expensive high temperature materials is confined to one or more final reaction stages. Reaction stages can incorporate perforated planar members with regions of oxygen ion transport membrane material in registry with such perforated regions form the separation zones and the catalytic reaction zones.

Method And Apparatus For Producing Synthesis Gas

US Patent:
2011014, Jun 16, 2011
Filed:
Dec 14, 2009
Appl. No.:
12/637308
Inventors:
John William Hemmings - Katy TX, US
Leo Bonnell - Houston TX, US
Earl T. Robinson - Mentor OH, US
International Classification:
B01J 19/00, B01J 8/00, B01D 53/22
US Classification:
422149, 96 4
Abstract:
A method and apparatus for reacting a hydrocarbon containing feed stream by steam methane reforming reactions to form a synthesis gas. The hydrocarbon containing feed is reacted within a reactor having stages in which the final stage from which a synthesis gas is discharged incorporates expensive high temperature materials such as oxide dispersed strengthened metals while upstream stages operate at a lower temperature allowing the use of more conventional high temperature alloys. Each of the reactor stages incorporate reactor elements having one or more separation zones to separate oxygen from an oxygen containing feed to support combustion of a fuel within adjacent combustion zones, thereby to generate heat to support the endothermic steam methane reforming reactions.
