NOVELTY - An oxygen rich gas (ORG), steam and fuel are supplied to a fuel processor (10), for producing hydrogen rich gas stream. The ORG, steam and fuel are contacted with partial oxidation catalyst and/or steam reforming catalyst to generate a hot reformate stream. The hot reformate stream is cooled, the sulfur-containing compounds are removed using a sulfur removal agent and a final reformate stream is produced.    USE - For producing hydrogen rich gas stream for fuel cell power generating systems and for use in vehicles as portions of a system for supplying energy to the vehicle.    ADVANTAGE - The process is efficiently performed and it overcomes high temperature problem of partial oxidation reactors and steam reformer, and provides excellent transient response capability. Since the zinc oxide converts hydrogen sulfide to zinc sulfide and effectively removes sulfur from the gas stream, the reduction in the catalytic activity is prevented. Leakage of pressure and reactants from the system is prevented using gasket. Additional preheating of the fuel in the fuel processor is prevented. The process reduces heat loss and increases efficiency of the processor. Carbon monoxide is reduced and the hydrogen in the reformate gas stream is increased by cooling the reforming gas.    DETAILED DESCRIPTION - An oxygen rich gas, steam and fuel are supplied to an inner reforming zone (30) of a fuel processor, for producing hydrogen rich gas stream. The inner reforming zone comprises a partial oxidation catalyst and/or a steam reforming catalyst. The oxygen rich gas, steam and fuel are contacted with the partial oxidation catalyst and/or the steam reforming catalyst to generate a hot reformate stream. The hot reformate stream is cooled in a cooling zone (50) to produce a cooled reformate stream. Sulfur-containing compounds are removed from the cooled reformate stream by contacting the cooled reformate stream with a sulfur removal agent. The cooled reformate stream is contacted with a catalyst which converts water (H2O) and carbon monoxide (CO) to carbon dioxide (CO2) and hydrogen in a water-gas-shift zone (70) to produce a final reformate stream in the fuel processor. An INDEPENDENT CLAIM is included for the fuel processor for generating the hydrogen rich gas from a fuel. The fuel processor comprises an inlet, an inner reforming zone, an outer reforming zone (40), a cooling zone, a sulfur removal zone (60) and a water-gas-shift zone. The inlet projects through an exterior housing (20) of the fuel processor attached to a steam line, an oxygen rich gas line and a fuel line. The reforming zone (30) comprises a side wall, a first end connected to the inlet, a partial oxidation catalyst and/or steam reforming catalyst and a second end. The reforming zone (40) comprises a side wall of the reforming zone (30), an outer side wall, a first end connected to the second end of the inner reforming zone and a second end. The cooling zone comprises a second end and a first end connected to the second end of the reforming zone (40). The sulfur removal zone comprises a sulfur removal agent a first end connected to the second end of the cooling zone and a second end. The water gas shift zone comprises a catalyst which catalyzes the conversion of CO and H2O, a first end connected to the second end of the sulfur removal zone and a second end connected to the outlet of the fuel processor.
