PURPOSE:To obtain the titled solid strong acid catalyst having a long catalytic life 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 a treating agent contg. sulfur and halogen, 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 is pretreated at 50-550 deg.C, then treated with a treating agent contg. sulfur and halogen (e.g., sulfonic acid fluoride, sulfuryl chloride, and thionyl chloride), and the 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 the synthesis of gasoline fractions from methanol synthesis gas. Accordingly, useful products can be selectively obtained by using said catalyst. |
