Studies of Olefin Alkylation over Pt-SO42-/ZrO2 Solid Superacid catalyst

Abstract

Abstract: The alkylation of isobutane with 1-butene over Pt-SO₄^2-/ZrO₂ catalysts prepared with different methods is studied.The results show that Pt-SO₄^2-/ZrO₂ catalysts have a high reaction activity and selectivity for alkylation, and the reaction conditions are the same as for SO₄^2-/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
