Method and system for removing carbon monoxide from a reformate gas stream for fuel cell application

摘要

A method of reducing carbon monoxide from a hydrocarbon reformate includes sequentially channeling an inital amount of reformate into a plurality of reactors comprising a bifunctional material. The carbon monoxide is preferentially chemisorbed by the bifunctional material such that a chemisorption capacity of the bifunctional material is reduced. An additional amount of the reformate is sequentially restricted into the reactors. A heated oxygen containing gas is sequentially passed through the reactors to convert the carbon monoxide to carbon dioxide. Thereby, the chemisorption capacity of the bifunctional material in the reactors is sequentially regenerated.
