Patent ID: 7632321

Claim:
A fuel processing system, comprising: a feedstock supply containing at least a carbon-containing feedstock and an aversive agent having a different composition than the carbon-containing feedstock, wherein the carbon-containing feedstock includes an alcohol that is a liquid at 25° C. and 1 atm, wherein the aversive agent includes at least one of an odorant that imparts an odor to the carbon-containing feedstock that is distinct from an odor of the carbon-containing feedstock, a flavorant that imparts a taste to the carbon-containing feedstock that is distinct from any taste of the carbon-containing feedstock, and a regurgitant, and further wherein the aversive agent is at least substantially free from sulfur compounds; a feed stream containing at least a mixture of the carbon-containing feedstock and the aversive agent from the feedstock supply; and a hydrogen-producing fuel processor in fluid communication with the feedstock supply and adapted to produce a product hydrogen stream containing hydrogen gas from the feed stream, wherein the fuel processor includes at least one hydrogen-producing region containing a reforming catalyst adapted to produce a mixed gas stream containing hydrogen gas and other gases from the feed stream, and further hydrogen gas forms at least a majority of the mixed gas stream.
