Abstract
The present invention relates to a catalyst for reforming that is employed when preparing a synthetic gas by reacting hydrocarbon such as methane with a reforming agent such as water, carbon dioxide, oxygen, air or the like. The present invention further relates to a process for producing a synthetic gas employing this catalyst for reforming. By employing the catalyst for reforming that is a mixed oxide having the composition expressed by the following formula in which the M and Co are in a highly dispersed state, it is possible to suppress precipitation of carbonaceous matters (carbon) when producing the synthetic gas.aM.bCo.cMg.dCa.eO(Where, a, b, c, d, and e are molar fractions, a+b+c+d=1, 0.0001≦a≦0.10, 0.0001≦b≦0.20, 0.70≦(c+d)≦0.9998, 0<c≦0.9998, 0≦d<0.9998, e=the number of oxygen necessary to maintain an electric charge balance with metallic elements. M is at least one type of element selected from among the group VIA elements, group VIIA elements, group VIII transition elements excluding Co, group IB elements, group IIB elements, group IVB elements and lanthanoid elements in the periodic table.)
