摘要: 研究了SO42-/ZrO2-Al2O3及Pt-SO42-/ZrO2-Al2O3固体超强酸催化剂与制备条件的关系,探讨了催化剂表面结构及晶化程度,并在N2活化条件下用脉冲色谱法考察了催化剂催化正丁烷异构化反应活性.结果表明,添加Al可提高催化剂的催化活性,降低反应温度,载铂对提高催化剂的活性和稳定性更为有效.

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
