A fuel processing system is disclosed. The system includes a steam reformer adapted to produce hydrogen from a feedstock consisting of water and at least one of an alcohol and a hydrocarbon feedstock. The hydrogen is produced by reacting the feedstock in the present of a reforming catalyst. The product stream is passed through a hydrogen-selective membrane module, at which the permeate stream is polished to remove trade carbon monoxide and carbon dioxide, and the byproduct stream is combusted to heat the reformer.

[ We claim:] [1.]1. A steam reformer, comprising:a shell having an outer surface;a reforming region within the shell and including a reforming catalyst bed adapted to receive a reforming feedstock and convert the feedstock into a reformate stream comprising hydrogen, carbon monoxide and carbon dioxide;a hydrogen purification module within the shell and including a hydrogen-selective membrane in fluid communication with the reforming catalyst bed and adapted to produce a permeate stream comprised of the portion of the reformate stream which passes through the membrane, and a byproduct stream comprised of the portion of the reformate stream which does not pass through the membrane;a polishing catalyst bed within the shell and including a methanation catalyst, wherein the polishing catalyst bed is in fluid communication with the hydrogen purification module and is adapted to receive the permeate stream therefrom and produce a product stream from the permeate stream, wherein the polishing catalyst bed is adapted to reduce the concentration of carbon dioxide and carbon monoxide in the permeate stream by catalytic reaction to produce methane; anda combustion chamber adapted to receive and combust a fuel stream with air to generate heat for heating the reformer, wherein the polishing catalyst bed is thermally coupled to the combustion chamber to be heated thereby.
