PREFERENTIAL OXIDATION REACTOR AND PROCESS

An apparatus for preferential oxidation of carbon monoxide in a reformate flow includes a reactor (10) defining a flow path (A) for a reformate flow; at least one catalyst bed (14) disposed along the flow path; and a distributor for distributing oxygen from an oxygen source to the at least one catalyst bed (14), the distributor including a conduit (16) positioned at least one of upstream of and through the at least one catalyst bed (14), the conduit (16) having a sidewall (32) permeable to flow of oxygen from within the conduit (16) to the at least one catalyst bed (14).
