摘要
Provided is a method and apparatus for producing hydrogen from an input gas stream containing carbon monoxide and steam that includes contacting the input gas stream with a catalyst. The catalyst contains an inorganic oxide support; a platinum group metal dispersed on the inorganic oxide support; and a methane suppressing dispersed on the inorganic oxide support. The methane suppressing component is selected from the group consisting of oxides of tin, oxides of gallium and combinations thereof. Also provided are preferred catalyst preparations.
