PURPOSE: To inhibit the deposition of carbon, to facilitate the control of the ratio of H2 to CO and to increase the rate of conversion by using a group VIII element and the oxide of a rare earth element as active components to produce a catalyst for production of synthesis gas.
CONSTITUTION: A group VIII element and the oxide of a rare earth element are used as active components and impregnation, coprecipitation, thermal decomposition, mixing or other preparation method is adopted to produce a catalyst for production of synthesis gas. The group VIII element may be Fe, Co, Ni, Pt, Pd, Rh, Ru or Ir but one or more among Rh, Ru and Ni are preferably used. The rare earth element may be La, Sm, Ce, Y, Eu, Gd, Yb or Tb. The pref. amt. of the group VIII element used is 0.01-80 wt.%, especially 0.1-50 wt.% of the amt. of the catalyst.
