Abstract:
1. A reactor for reducing a carbon monoxide (CO) content of a reformate stream comprising: a support assembly including a reaction section having a plurality of substrates configured for providing a first plurality of flow channels for reformate flow and a second plurality of flow channels for coolant flow, wherein each of said plurality of substrates has a first surface and a second surface opposite thereto, wherein at least a portion of said plurality of substrates has said first surface exposed to reformate and has said second surface in heat transfer relationship with a coolant; a sorption material coating at least a portion of each first surface of said substrates; a catalyst coating at least a portion of each first surface of said substrates, wherein said portion of said first surface having a sorption material coating is discrete from said portion of said first surface having said catalyst coating; wherein said sorption material is active for adsorbing carbon monoxide (CO) to reduce the CO content of the reformate stream flowing through said first plurality of flow channels when the reactor is operating in a first mode; and wherein said catalyst enables a preferential oxidation reaction of CO to reduce the CO content of the reformate stream when the reactor is operating in a second mode.
