Patent ID: 8297043

Claim:
A power generation system, comprising: a diesel engine operative to produce an exhaust stream containing excess O 2 ; and a fuel processor for generating a reductant in at least a portion of the exhaust stream and configured to be rapidly heated under overall lean conditions while within the exhaust stream by combustion of hydrocarbon fuel in the exhaust stream and configured to be operated to reform at least a portion of hydrocarbon fuel within the exhaust stream under overall rich conditions; wherein the fuel processor comprises an exhaust stream inlet; an exhaust stream outlet; a monolith structural support between the inlet and the outlet, the monolith structural support being formed from metal foils having a thickness of 100 microns or less; and one or more catalytic coatings applied to the monolith structural support, the coatings consisting essentially of substrates and 0.1-20% by weight catalytically active elements; wherein the catalytically active elements of the fuel processor as a whole are primarily oxidation catalysts, primarily reforming catalysts, or primarily oxidation and reforming catalysts; and the substrates are selected from the group consisting of aluminum oxide, silicon oxide, zirconium oxide, and mixtures thereof, optionally containing additives, and optionally stabilized and have a surface area of at least 15 m 2 /g; wherein the fuel processor is effective at a temperature in the range from 500° C. to 700° C. to catalyze reaction of diesel engine fuel with H 2 O and CO 2 to produce H 2 and CO.
