苯的重量吸附t-作图法在研究沸石分子筛催化剂中的应用
THE APPLICATION OF de-BOER’S t-PLOT METHOD TO THE RESEARCH OF ZEOLITE CATALYSTS BY GRAVIMETRIC BENZENE ADSORPTION
【摘要】 <正> 在沸石分子筛催化剂的研究中,de Boer 等人提出的t-作图法在低温氮吸附容量法方面,已经证明对于测定催化剂的分子筛含量及无定形载体比表面大小是个有力的工具。另一方面,目前在许多工厂、实验室仍使用着的石英弹簧重量吸附法则有简单易行及可同时进行若干样品测定的优点。为此,我们尝试将t-作图法推广用于苯的重量
【Abstract】 By applying the t-plot method to the data of benzene adsorption at25℃ on the samples prepared by mixing NaY zeolite and amorphous alu-minium silicate,it demonstrated that the t-plot method with benzene gra-vimetric adsorption can be used to determine both the zeolite content andthe specific surface area of support.Two commercially available catalysts which contain zeolite have beenanalysed by this method,the results agree with those of low temperatureN2 adsorption.
