Abstract:
1. A device for producing a reducing gas, comprising: an inlet, a fuel injector, a catalytic zone comprising an oxidation catalyst and a reforming catalyst, an outlet, and a reservoir comprising a fuel, wherein said reservoir is in fluid communication with said fuel injector, wherein said fuel injector is configured to inject fuel upstream from said catalytic zone into at least a portion of an oxygen containing gas stream flowing from said inlet to said outlet and through said catalytic zone such that rich and lean zones are formed in said gas stream, and wherein said injected fuel flows through said catalytic zone, wherein said fuel injector is configured to inject a sufficient amount of fuel to form a rich zone in said gas stream such that as the rich zone flows through the catalytic zone, a portion of the injected fuel in the rich zone is oxidized on the oxidation catalyst and at least a portion of the remaining injected fuel in the rich zone is reformed on the reforming catalyst, thereby producing a reducing gas stream.
