  • Methods and systems for generating hydrogen and separating carbon dioxide
    Patent number: 8926942
    Abstract: Methods and systems for generating hydrogen and separating carbon dioxide from a feed stream including hydro-carbons and water are disclosed. In some embodiments, the method includes the following: providing a catalytic chamber including a monolithic structure having surfaces coated with carbon dioxide adsorbing materials and one or more washcoated layers of combined steam reforming, water gas shift, and combustion catalysts; directing the feed stream into said catalytic chamber; controlling the feed stream 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 monolithic structure; and adsorbing said carbon dioxide generated by heating the feed stream, wherein said carbon dioxide is adsorbed onto carbon dioxide adsorbing materials on said surfaces of said monolithic structure.
