Using mordern physical chemistry techniques (such as XRD、 TG-DTA、 IR、 XPS and 〓Xe-NMR)、 chemical adsorption techniques (NH〓-TPD、 H〓-TPD、 TPO、 TPR etc.) and pulse flow microreaction of n-hexane、 methylcyclopentene and n-hexane containing 0.2ppm thiophene, we studied mainly the following three points:(1). the changes occured during the calcination pretreatment of Pt ammine complex supported on β and L zeolites;(2). the effect of structure and acidity-basicity of zeolite on the dispersion and electron state of Pt particles; and (3). the influence of second metal component on the reactivity of nhexane aromatization and sulphur-resistance of Pt/L zeolite catalyst. Several interesting and valuable results are obtained and summerized as follows

In the acylation reaction between anisole with acetyl chloride, The catalyst of ZnCl〓/HY-98 prepared by MWI had the best catalytic activity and the selectivity of p-methoxy acetopheone. The catalytic active centers were ZnCl〓 dispersed in zeolite and the Bronsted acid sites in HY-98 zeolite itself.

在苯甲醚与乙酰氯的酰化反应中，微波固相法制备的ZnCl〓／Y催化剂有相对较好的催化活性和选择性，起催化作用的主要是分散在分子筛表面的ZnCl〓和分子筛本身的B酸。
