<P>PROBLEM TO BE SOLVED: To provide a catalyst and a method for reforming a hydrocarbon which are suitable for reforming the hydrocarbon at a high reaction rate and by which the hydrocarbon containing sulfur compound can be reformed with high efficiency by suppressing influence of sulfur poisoning as much as possible. <P>SOLUTION: The reforming catalyst comprises a multiple oxide having a composition expressed by the formula, aM-bNi-cMg-dO. Otherwise, the reforming catalyst comprises the multiple oxide obtained by adding at least one oxide chosen from silica, alumina and zeolite to either one or both of the multiple oxide having composition expressed by following formula and multiple oxide containing Ni and Mg. In the formula, a, b, c, and d are each a mol ratio; a+b+c=1; 0.02≤a≤0.99; 0.01≤b≤0.99; 0.01≤c≤0.97; d is the number required for oxygen to maintain electrical neutrality with a positive element, M is at least one element chosen from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Cu, Zn, Cd, Al and Si. <P>COPYRIGHT: (C)2004,JPO |
