iso-Butane/1-Butene Alkylation Reaction and Deactivation of Superacid(SO42-/ZrO2) Catalysts

Abstract

Abstract: The acidity and reactivity of superacid(SO^2-₄/ZrO₂) catalysts in the iso-butane/1-butene alkylation were investigated. It was found that the acidity of the solid superacid is related to the baking temperature, and higher baking temperature is advantageous to increasing the acidic strength of the catalysts, but too high baking temperature resulted in the decrease of the acidic strength and amount. It was also found that the reactivity of superacid(SO^2-₄/ZrO₂) catalysts in the iso-butane/1-butene alkylation corresponds to the acidity, the stronger the acidity is, the higher the reactivity is. But the stronger acidity resulted in the fast decrease of activity, which was attributed to the fast carbon deposit on the catalyst surface.

Key words: Superacid(SO₂-4/ZrO₂), iso-Butane, 1-Butene, Alkylation
