The hydrocarbon-reforming catalyst comprising a composite oxide having a composition represented by the following formula (I) in which Co, Ni and M are dispersed in the composite oxide and a process for producing a synthesis gas by using the catalyst are provided. aM.cndot.bCo.cndot.cNi.cndot.dMg.cndot.eCa.cndot.fO (I) wherein a, b, c, d, e, and f are molar fractions, a+b+c+d+e = 1, 0.0001 < a <= 0.20, 0 < b <= 0.20, 0 <= c <= 0.20, 0.001 < (b+c) <= 0.20, 0.60 <= (d+e) <= 0.9989, 0 < d < 0.9989, 0 < e < 0.9989, f = the number necessary for element to keep charge equilibrium with oxygen. And M is at least one element among Group 3B elements and Group 6A elements in the Periodic Table. The reforming catalyst is able to maintain a high catalytic activity over a long period in reforming hydrocarbons.

La présente invention a pour objet un catalyseur de reformage qui comprend un oxyde composite ayant une composition représentée par la formule (I) suivante, les Co, Ni et M ayant été dispersés dans l'oxyde composite ; et un procédé pour la production de gaz de synthèse au moyen du catalyseur. aM bCo cNi dMg eCa fO (I) [Dans la formule (I), a, b, c, d, e, et f indiquent les fractions molaires et satisfont à la relation suivante : a+b+c+d+e=1, 0,0001<a=0,20, 0<b=0,20, 0=c=0,20, 0,001<(b+c)=0,20, 0,60=(d+e)=0,9989, 0<d<0,9989, 0<e<0,9989, et f est un nombre nécessaire pour conserver un équilibre des charges entre les éléments et l'oxygène. M est au moins un élément choisi parmi les éléments des Groupes 3B et 6A du tableau périodique.] Le catalyseur de reformage peut conserver un niveau élevé d'activité catalytique dans le reformage d'un hydrocarbure sur la durée.
