| 摘 要： | 用无水浸渍法制备了膨润土负载型固体酸催化剂.通过XRD、BET、SEM、XPS等手段对催化剂进行表征分析.结果表明,负载物与膨润土有良好的结合性能,形成了新的物相或无定形状态.固体酸表面粗糙,有许多的微孔,表面的这种变化有利于在催化反应时,反应物向酸性中心靠近,提高催化活性,同时也使固体酸的稳定性提高. |

| Abstract: | The paper deals with the preparatin of solid acid catalyst loaded on Bentonite through an impregnating method. The charac-teriozations of the catalysts were also analyzed with XRD, BET, SEM, XPS. The results show that the adhesiveness between Lewis acid and Bentonite is very good, and they have been formed new conditions. The whole structure becomes more loose and rugged. This change is helpful in the catalytic reaction, and can improve the catalytic activity and the stability of solid acid. |
