| Abstract: | The effects of the conditions such as calcination time and temperature for preparing solid superacid catalysts, SO_4/ZrO_2-Al_2O_3(SZA) and Pt-SO_4/ZrO_2-Al_2O_3, 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 Al_2O_3 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. |
