NOVELTY - Process-1 for steam reforming of a hydrocarbonaceous fuel, comprises: providing a reactant mixture (22) comprising water and the hydrocarbonaceous fuel; and contacting the reactant mixture with an alumina-yttria-stabilized zirconia (YSZ)-supported nickel aluminate spinel catalyst (I) under conditions where the reactant gas mixture is at least partially steam reformed into a product gas mixture including hydrogen and carbon monoxide.    USE - (I) is useful in steam reforming of a liquid hydrocarbonaceous fuel to give hydrogen and carbon monoxide. The synthesis gas is useful as a feed material for fuel cells (claimed). The hydrogen is useful for refineries and petrochemical processes e.g. fossil fuels processing and ammonia production, and solid oxide fuel cells targeting stable, clean, chemical-to electrical energy conversion applications.    ADVANTAGE - (I) is substantially free of metallic nickel and nickel oxide. (I), in the process-1, enhances the production of hydrogen and carbon monoxide. The process using (I), lowers the catalyst deactivation rate while maintaining high hydrogen concentration in the product mixture and high conversion rates of the hydrocarbonaceous fuel. (I) is a low-cost and effective option for steam reforming. In the process, no significant coking on the active part of (I), even at high reaction severity is required. (I) is stable i.e. it has an improved resistance to carbon formation and a longer catalyst lifetime.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a synthesis gas for fuel cells obtained by the process;    (2) a process-2 for the production of hydrogen comprising: submitting a reactant mixture including a hydrocarbonaceous fuel and water under steam reforming conditions; and contacting the reactant mixture under steam reforming conditions with (I);    (3) the catalyst for steam reforming of a hydrocarbonaceous fuel, comprising: a nickel aluminate spinel-based catalytically active material; and a support material comprising alumina and zirconia;    (4) the preparation of (I) comprising: mechanically mixing alumina and YSZ powders to form a mixed powder; wet impregnating of the mixed powders with an aqueous nitrate solution to form an impregnated powder; and submitting the impregnated powder under conditions to allow decomposition of nitrate and formation of nickel aluminate.
