Improved fuel processing systems convert a hydrocarbon fuel into a reformate stream comprising hydrogen. Improved steam reformers and fuel processing systems employ steam reforming catalyst compositions that are oxygen-tolerant and/or sulfur-tolerant. Improved fuel processing systems employ shift reactors comprise shift catalyst compositions that are oxygen-tolerant and self-reducing. Improved fuel processing systems also comprise a preoxidizer or first-stage selective oxidizer, shift reactor, and selective oxidizer connected in series. An improved integrated reactor comprises a metal oxide bed and shift catalyst bed, and fuel processing systems comprising the improved integrated reactor. |
