PURPOSE:To obtain a steam reforming catalyst ensuring a low reaction pressure, forming a small amt. of carbon even in a low molar ratio of steam to carbon and requiring regeneration at a prolonged interval by incorporating 5-30wt.% Ni, 0.5-5wt.% Mn, 0.5-5wt.% Fe and 2-10wt.% Ba into an alumina carrier. CONSTITUTION:In order to prevent the deterioration of hydrocarbon reforming performance and the reduction of the surface area of an effective Ni catalyst, 5-30wt.% Ni is incorporated into an alumina carrier. In order to prevent the deterioration of carbon formation inhibiting performance and reforming performance, 0.5-5wt.% Mn and 0.5-5wt.% Fe are incorporated into the alumina carrier. In order to maintain high reforming activity and to enhance carbon formation inhibiting effect, 2-10wt.% Ba is incorporated into the alumina carrier. The resulting steam reforming catalyst ensures a low reaction pressure, forms a small amt. of carbon even in a low molar ratio of steam to carbon and requires regeneration at a prolonged interval. |
