PURPOSE:To product an 8-15C oil intermediate fraction from an isoparaffin and an olefin under mild reaction conditions, by the use of a solid superstrong acid catalyst containing a group VIII metal or a rare earth element. CONSTITUTION:A 4-6C isoparaffin and olefin are catalytically reacted with each other in the presence of the below-defined solid superstrong acid catalyst so as to be converted into an 8-15C hydrocarbon, thereby obtaining an oil intermediate fraction. The catalyst is obtd. by incorporating a group VIII metal or a rare earth metal in a carrier comprised of a hydroxide or oxide of a group IV metal and/or a hydroxide or oxide of a group III metal, then treating the formed catalyst precursor with a treating agent contg. sulfur ion and finally burning the treated catalyst for stabilization thereof. Examples of the group VIII metal include at least one member selected from among nickel, platinum, palladium, and rhodium. Examples of the rare earth elements include at least one member selected from among lanthanum, cerium, praseodymium, and neodymium. These metals and elements may be in a compound form with other elements.
