PURPOSE:To obtain a solid acid catalyst having excellent alkylation activity and selectivity, by causing a carrier of a compound metal-compound of IV group contain a sulfate radical, while applying burning and stabilization thereto. CONSTITUTION:A carrier of compound metal hydroxide or compound metal oxide composed of two or more of metals of IV group of a periodic table, such as Ti, Zr, is caused to contain a sulfate radical or a precursor thereof, such as ammonium sulfate or ammonium sulfite, which is thereafter burned and stabilized for about 0.5-10h at a temperature of about 400-800 deg.C, preferably about 450-700 deg.C. The catalyst so obtained shows a high activity in alkylation reaction of isobutane by olefin and has a high selectivity for trimethylpentane, which is a hydrocarbon having a high octane value among the products of said alkylation reaction. |
