TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Condition: The hot reformate stream is at 600-800degreesC and the hot reformate is cooled by directly injecting water to the hot reformate stream. The cooled reformate stream is at 200-400degreesC after cooling. Preferred Catalysts: The catalyst of reforming zone (30) is a combined partial oxidation and steam reforming catalyst. The partial oxidation and steam reforming catalyst comprises a transition metal and an oxide-ion conducting portion. The transition metal is platinum, palladium, ruthenium, rhodium, iridium, iron, cobalt, nickel, copper, silver and/or gold. The oxide-iron conducting portion is cerium oxide from the group crystallizing in the fluorite structure of lanthanum gallium oxide (LaGaO3). The combined partial oxidation and steam reforming catalyst is platinum or gadolinium doped ceria. The inner reforming zone is formed of stainless steel. The inner reforming zone is formed of stainless steel. Preferred Process: The hot reformate gas is passed through the outer reforming zone comprising partial oxidation catalyst and/or steam reforming catalyst. The steam and fuel are supplied to the inner reforming zone through a single pipe as a mixture and the oxygen rich gas is separately supplied to the inner reforming zone, through a tube surrounded by the inner reforming zone. The steam, fuel and oxygen rich gas are supplied through a single pipe as a mixture. Steam and oxygen rich gas are heated by passing through a steam heating zone (80) and air heating zone (90), respectively in the processor, before introducing into the single pipe. The final reformate stream is supplied to a preferential oxidation unit comprising a catalyst which oxidizes carbon monoxide to carbon dioxide. The cooled reformate stream is contacted with at least two different catalyst to form a final reformate stream. Preferred Fuel: The fuel has a formula CnHmOp, where n is the average number of carbon atoms/molecule of the fuel and is 1-20, m is the average number of hydrogen atoms per molecule of the fuel and is 2-42, p is average number of oxygen atoms per molecule of the fuel and is 0-12. Preferred Ratio: The molar ratio of O2 supplied to the inner reforming zone per molecule of fuel is represented as x and has 0.5-1.5x0, x0 is 0.312n-0.5p+0.5(deltaHf,fuel/approximatelydHf,water), where deltaHf,fuel and deltaHf,water are the heat of formation of fuel and water, respectively. The molar ratio of steam supplied to the inner reforming zone per mole of fuel is 0.8(2n-2x-p)-3.0(2n-2x-p). SPECIFIC COMPOUNDS - The sulfur removal agent is zinc oxide.
