Abstract: A self-inerting fuel processing system is provided. In one embodiment, the present fuel processing system comprises a fuel processor comprising a reformer, at least one self-reducing catalyst bed, a recycle loop for circulating a gas stream through the fuel processor and the self-reducing catalyst bed(s) during shutdown of the fuel processing system, and an oxidant supply for introducing oxidant into the recycle loop during shutdown of the fuel processing system. A method for shutting down the fuel processing system is provided. A fuel cell electric power generation system incorporating the present fuel processing system is also provided.

Abstract: A fuel processing reactor is provided, comprising a shift catalyst bed disposed in a shell and tube reactor. The thermal stress on the present reactor during normal operation is reduced by cooling/heating both the shell and the tubes in the reactor. The present reactor may further comprise other beds such as hydrodesulfurizer catalyst beds, metal oxide beds, or sulfur polisher beds.
