| 摘 要： | 采用静态液相吸附法，考察了ｎＣ６与ｉＣ８分别在５Ａ和ＺＳＭ５分子筛上的吸附平衡情况。研究结果发现，溶液浓度对吸附平衡时间和吸附量都有较大影响，剂／油值对平衡吸附量影响不大。对５Ａ分子筛的吸附平衡数据进行了拟合，其吸附等温线方程与Ｌａｎｇｍｕｉｒ方程基本吻合，而吸附速率曲线符合Ｂａｎｇｈａｍ方程

| Abstract: | The adsorption characteristics of n C 6/ i C 8 solution on 5A and ZSM 5 molecular sieves are studied by using static liquid phase adsorption method. It is found that the concentration of the solution has great effects on the time of the adsorption equilibrium and the adsorptive power. The adsorption isotherm obeys the Langmuir equation. The dynamic curve can be described by the Bangham equation. |
