NOVELTY - Providing a method for producing hydrogen-rich gas from sulfur-containing carbonaceous fuels which eliminate the requirement for sulfur removal prior to conversion of the carbonaceous fuels to hydrogen-rich gas.    USE - For producing hydrogen rich gas used in fuel cell generating systems or other systems which generally are not sulfur tolerant.    ADVANTAGE - The method eliminates the requirement for sulfur removal before conversion of carbonaceous fuel to hydrogen rich gas. The method converts fuel into hydrogen rich gas at less than 800degrees C which is several 100degrees C lower than the temperature employed in conventional non-catalytic process. Hence lowers cost of reactor materials. The method reduces concentration of carbon monoxide in raw reformate gas, thereby permits smaller downstream processing equipment such as water gas shift reactor. The catalyst is not degraded or poisoned by sulfur impurities in the fuel. The sulfur impurities such as complex benzothiophene is converted into hydrogen sulfide, hydrogen and carbon dioxide.    DETAILED DESCRIPTION - Sulfur-containing carbonaceous fuel reforming method, involves forming mixture (A) of fuel, water and oxidant, and contacting mixture (A) with a catalyst composition comprising a dehydrogenation portion, an oxidation portion and a hydrodesulfurization portion, to form hydrogen-containing gas stream.    INDEPENDENT CLAIMS are also included for:    (1) reforming a sulfur-containing carbonaceous fuel comprising:    (a) mixing the sulfur-containing carbonaceous fuel with H2O and an oxidant, forming a fuel/H2O/oxidant mixture; and    (b) contacting the fuel/H2O/oxidant mixture with a catalyst composition comprising a dehydrogenation portion comprising metal and/or a metal alloy selected from Group VIII transition metals, an oxidation portion comprising a ceramic oxide powder and a dopant selected from rare earth metals, alkaline earth metals and/or alkali metals, and a hydrodesulfurization poriton comprising a material selected from Group IV rare earth metal sulfides, Group IV rare earth metal sulfates and/or their stoichiometric metals, resulting in formation of a hydrogen-containing gas stream;    (2) reforming sulfur-containing carbonaceous fuel comprising:    (i) contacting the fuel/H2O/oxidant mixture with a catalyst composition comprising a dehydrogenation portion, an oxidation portion, and a hydrodesulfurization portion comprising a material selected from Group IV rare earth metal sulfides, Group IV rare earth metal sulfates and/or their stoichiometric metals, resulting in formation of a hydrogen-containing gas stream.
