PROBLEM TO BE SOLVED: To obtain a catalyst for production of synthetic gas by a reforming reaction of methane excellent in reducing power of Ni and having high activity by modifying a metal Ni-contg. alkaline earth metal oxide solid son. with a specified amt. of a compd. of at least one kind of metal of the platinum group by carrying or mixing. SOLUTION: A metal Ni-contg. alkaline earth metal oxide solid soln. having a compsn. represented by the formula aNi.bMg.cCa.dO is modified before reductive activation treatment with 0.02-0.3wt.% (expressed in terms of metal) compd. of at least one kind of metal of the platinum group such as Pt, Pd, Ru or Rh by carrying the compd. on the solid soln. or mixing them to obtain the objective catalyst compsn. for production of synthetic gas consisting of H and CO. In the formula, (a), (b), (c) and (d) show mol fraction, respectively a+b+c=1, 0.005<=a<=0.07, 0.93<=(b+c)<=0.05, 0<b<=0.995, 0<c<=0.995 and (d) is the number required to allow Ni, Mg and Ca to keep electric charge equilibrium with 0. |
