Abstract

Abstract: The effects of the conditions such as calcination time and temperature for preparing solid superacid catalysts, SO₄/ZrO₂-Al₂O₃(SZA) and Pt-SO₄/ZrO₂-Al₂O₃, on their surface structure and crystallizability were studied. The reaction performance of the catalysts mentioned above for isomerization of n-butane was examined using pulse technique. The results showed that addition of Al₂O₃ could increase the catalytic activity and selectivity, and decrease the reaction temperature for getting the same activity; addition of Pt to SZA could increase the catalyst catalytic activity and stability more effectively.

Key words: SO₄/ZrO₂-Al₂O₃, Pt-SO₄/ZrO₂-Al₂O₃, Solid superacid, Isomerization of n-butane
