To provide a method for catalytically reforming a supplied hydrocarbon material with steam, capable of reforming the hydrocarbon material in a state improved in durability against a sulfur poisoning and sintering, by bringing the supplied hydrocarbon material into contact with a nickel catalyst carried on a magnesium- aluminum spinel material which has been calcined at a specific calcination temperature and has a specified specific surface area or larger.
This method for catalytically reforming a supplied hydrocarbon material with steam comprises bringing the supplied hydrocarbon material into contact with a nickel catalyst carried on a magnesium-aluminum spinel: MgO.xAl2O3 material. Therein, the spinel carrier material is obtained by a calcination at Tc [°C] (Tc is ≥400°C) and has a larger specific surface area A sp[m2/g] than 400.exp(-Tc/400°C). The spinel carrier material having a high specific surface area has improved surface resistance and can maintain a sufficient catalytic activity, because the rate of a sulfur- covered portion on the surface of the spinel carrier material is small even on the employment of a supplied hydrocarbon material containing sulfur compounds in a large amount. The activity of the catalyst can be improved by the addition of Zr, Y, W, La, Ce, Lanthanoids, etc.
