一、前言烃类的许多重要催化反应,如裂解、异构化、烃化、聚合等,都与催化剂的酸性有着密切的关系,因此催化剂表面酸性的测试就成了研究催化剂酸性对不同反应的催化活性和选择性的关系的有效工具,对改进现有催化剂和研制新催化剂也有重要的作用。对固体表面酸性的测试,已有文献述评。虽然最常用的是正丁胺吸附指示剂 I. INTRODUCTION Many important catalytic reactions of hydrocarbons, such as cracking, isomerization, alkylation, polymerization and so on, are closely related to the acidity of the catalyst. Therefore, the testing of the acidity of the catalyst surface has become the key to study the effect of the catalyst acidity on different reactions An effective tool for the relationship between catalytic activity and selectivity, it also plays an important role in improving existing catalysts and developing new catalysts. Acid surface solid test, has been literature review. Although the most commonly used n-butylamine adsorption indicator
