摘要

用CAHN2000型电子天平在温度303.15～443.15 K、压力3.47～2116.6 Pa条件下测定对二甲苯、间二甲苯、邻二甲苯及甲苯在KY型沸石上的吸附平衡数据.根据Polanyi吸附势理论

以初始吸附热表征的亲和力系数作为调节参数

对测定的吸附平衡数据进行了关联

实验数据均落在一条特征曲线附近

得到了满意的结果.

Abstract

The adsorption equilibria of p-xylene

m-xylene

o-xylene and toluene on KY zeolite were measured under temperature range (303.15～443.15K) and low pressure (3.47～2116.6 Pa) by CAHN2000 Electrobalance. All the experimental data obtained in this work can be fitted as a generalized characteristic curve of Polanyi adsorption potential theory by using the parameter of the initial heat of adsorption

which is estimated reasonably.
