Abstract

Abstract: Anew type of alkylation catalysts for isobutane with butenes were prepared by ZrO₂ impregnated with H₃PO₄-BF₃or H₃PO₄-BF₃-H₂SO₄ and dried at lower temperature. The effects of the calcination temperature of ZrO₂, the concentration of impregnation solution, the addition of BF₃ and H₂SO₄, and the reaction temperature on the activity of catalysts were researched. Acidity and stability of these catalysts were also discussed.

Key words: Alkylation, Isobutane, Butenes, Catalyst
