    摘要: A preferential oxidation reactor is provided including a plurality of reactor sections. The reactor sections are individually optimized for operating at a preferred reaction temperature. In one embodiment, each reactor subsection includes a respective coolant flow for manipulating the operating temperature of the respective subsection. In another embodiment, a first section includes a lower temperature catalyst substrate, a second reactor section includes a higher temperature (i.e. normal) catalyst substrate and a third reactor section includes a lower temperature catalyst substrate. Yet another embodiment includes modifying the catalyst substrates of the respective subsections through the inclusion of promoters. Still another embodiment includes varying a density of the catalyst substrate across the reactor sections. Each of the embodiments enable quick light-off of the reactor, while limiting a reverse water-gas shift reaction.

    摘要: A fuel processor system includes first and second reactors each having an inlet that receives fuel from a fuel supply and an outlet that discharges a reformate containing hydrogen. The reactors are operable to reform the fuel to form the reformates. The second reactor is coupled in parallel with the first reactor with the reformates produced by each combining to form a reformate flow. The first reactor can be an autothermal reforming reactor and the second reactor can be a steam reforming reactor. The first and second reactors are controlled differently to provide quick startup and transient capability while providing improved overall efficiency under normal operation.
