Abstract: The alkylation of isobutane with 1-butene over Pt-SO42-/ZrO2 catalysts prepared with different methods is studied.The results show that Pt-SO42-/ZrO2 catalysts have a high reaction activity and selectivity for alkylation, and the reaction conditions are the same as for SO42-/ZrO2 catalyst.The addition and the adding methods of Pt did not affect the catalytic property, the crystal forms and stucture, and strength of the superacids according to the results of FTIR, XRD, XPSand acid strength measurement.When the alkylation reaction of isobutane with 1-butene takes place in hydrogen, the coke yield over the catalysts added with Pt is decreased and the life of the catalysts is extended.

Key words: Alkylation, Superacid, Supported Pt
