摘要
本文研究了用盐酸处理γ－Ａｌ＿２Ｏ＿３对Ａｌ＿２Ｏ＿３的表面性质以及Ｐｔ／Ａｌ＿Ｏ＿３的表面性质和反应性能的影响。结果表明盐酸处理的γ－Ａｌ＿２Ｏ＿３酸中心（强酸和弱酸中心）数目增加，Ｐｔ在Ａｌ＿２Ｏ＿３表面的表现分散度或Ｐｔ的低温活性中心数增加，与此同时，Ｐｔ的高温活性中心数也增多，从而使Ｐｔ／Ａｌ＿２Ｏ＿３的氢解、异构化和脱氢环化活性都增加。
The effect of hydrochloric acid treatment on the surface characteristics of γ-Al_2O_3 and the surface characteristics and reactivity of Pt/Al_2O_3 were studied.It was foundthat hydrochloric acid treatmeat might increase the number of acid centers(both strong andweak acid centers)of γ-Al_2O_3, and the number of both low temperature and high tempera-ture active centers of Pt/Al_2O_3.The activity of Pt/Al_2O_3 were therefore also for hydrogenolysis,isomerization and dehydrocyclization reaction increased.
