    Abstract: The present invention relates to a process for the steam reforming of a hydrocarbon, comprising: passing a feed stream comprising hydrocarbon gas and steam into at least one reaction chamber; said reaction chamber comprising a catalyst that catalyzes the reaction of said hydrocarbon gas and steam to produce a gaseous mixture comprising at least carbon monoxide and hydrogen gas; wherein the contact time of the reactant with the catalyst is less than 0.3 seconds; transferring heat from at least one heat exchanger into the at least one reaction chamber; and producing more than 0.01 SLPM of hydrogen gas per cubic centimeter of reactor volume, where reactor volume is defined as the sum of the volume of the reaction chamber(s) and heat exchange chamber(s) including the volume of chamber walls.

    Abstract: The present invention includes a catalyst having (a) a non-metallic support having a plurality of pores; (b) a metal heteropoly acid salt that is insoluble in a polar solvent on the non-metallic support; wherein at least a portion of the metal heteropoly acid salt is dispersed within said plurality of pores. The present invention also includes a method of depositing a metal heteropoly acid salt that is insoluble in a polar solvent onto a non-metalli c support having a plurality of pores. The method has the steps of: (a) obtaining a first solution containing a first precursor of a metal salt cation; (b) obtaining a second solution containing a second precursor of a heteropoly acid anion in a solvent having a limited dissolution potential fo r said first precursor; (c) impregnating the non-metallic support with the fir st precursor forming a first precursor deposit within the plurality of pores, forming a first precursor impregnated support; (d) heating said first precursor impregnated support forming a bonded first precursor impregnated support; (e) impregnating the second precursor that reacts with the precurso r deposit and forms the metal heteropoly acid salt.
