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
