CATALYST ABSTRACT OF THE DISCLOSURE A catalyst comprising 10 to 30 wt.% of nickel 85 nickel oxide, 20 to 60 wt.% of calcium as calcium oxide, 10 to 70 wt.% of aluminum as aluminum oxide and containing less than 1 wt.% of silicon dioxide. The catalyst is prepared by using: as the starting material for the nickel component, fine particles of nickel oxide obtained by heating a nickel com- pound which is decomposed to nickel oxide by heating at a temperature in the range of 400° to 800°C. in the presence of oxygen; as the starting mate- rial for the calcium component, calcium oxide per se or a calcium compound which is decomposed to calcium oxide by heating and; as the starting mate- rial for the aluminum component, alumina cement of a high purity. The cat- alyst is prepared by mixing and kneading the starting materials with water, molding the same, then keeping the catalyst composition under a highly humid atmosphere at a temperature in the range of 5° to 35°C. for longer than one day for hydrating and hardening the cement and thereafter sintering the same at a temperature in the range of 550° to 1200°C.
