| 摘 要： | 本文采用溶胶-凝胶法制备Pt／Al2O3催化剂，考察了焙烧温度、还原温度对催化剂表面及结构性质的影响，并研究了该催化剂在二聚物脱氢反应中的脱氢活性，以及与浸渍法制备的催化剂进行了对比。对比结果显示，溶胶-凝胶法制备的催化剂热稳定性及活性组分抗烧结能力比浸渍法制备的催化剂高得多。

| Abstract: | The Pt/Al2O3 catalyst was prepared by sol-gel method. The influence of calcination temperature and reduction temperature on the surface of catalyst and the structural properties was investigated. The activity of catalyst during dimeric dehydrogenation was studied, and the catalyst which was prepraed by impregnation was compared as well. The results showed that the thermal satability and anti-sintering ability of catalyst prepraed by sol-gel method were much higher than the catalyst prepared by impregnation. |
