PURPOSE:To manufacture a catalyst exhibiting catalytic activity in the skeletal isomerization of hydrocarbons by treating the hydroxide or oxide of a group IV metal carrying a group VIII metal and/or the hydroxide or oxide of a group III metal with sulfuric acid, etc., and calcining the material. CONSTITUTION:The hydroxide or oxide of a group IV metal carrying 0.01-10wt% group VIII metal and/or the hydroxide or oxide of a group III metal are pretreated at 50-550 deg.C, then treated with a treating agent contg. a sulfate radical, and calcined and stabilized at 450-800 deg.C. The solid acid catalyst thus obtained has excellent stability of activity, and exhibits catalytic activity in the skeletal isomerization of hydrocarbons, alkylation, aromatization, polymerization, decomposition, and synthesis of gasoline fractions from methanol-synthesis gas. Accordingly, useful products can be obtained selectively by using said catalyst. |
