Abstract:
1. A method of generating hydrogen and separating carbon dioxide from a feed stream including hydrocarbons and water, the method comprising: providing a first catalytic chamber including surfaces coated with carbon dioxide adsorbing materials and one or more washcoated layers of combined steam reforming and water gas shift catalysts; providing a second catalytic chamber including surfaces coated with carbon dioxide adsorbing materials and one or more washcoated layers of combined steam reforming and water gas shift catalysts; controlling the feed stream to be alternatingly fed to at least one of said first and second catalytic chamber so that it has a temperature range that allows the reactive generation of carbon dioxide and hydrogen gas but does not cause substantial development of coke between hydrocarbons in the feed stream and said surfaces of said catalytic chamber; and adsorbing and desorbing said carbon dioxide generated by heating the feed stream, wherein said carbon dioxide is alternatingly adsorbed onto and desorbed from said surfaces of said first and second catalytic chambers coated with carbon dioxide adsorbing materials.
