| 摘 要： | 研究了不同分子筛对乙醇中微量水的吸附性能,结果表明4A分子筛的吸附效果最好;测定了不同温度下乙醇中微量水在4A分子筛上的静态吸附平衡数据,并用Langmuir和Freundlic两个吸附等温式分别进行拟合,发现具有较好的吻合度（相关系数大于0.98）;采用固定床测定了不同粒径、不同初始浓度、不同床层高度、不同流量下的动态穿透曲线,为吸附工艺设计提供参考。

| Abstract: | The adsorption characteristics of small amount of water in ethanol on different molecular sieves were studied in this paper, and the results showed that the 4A molecular sieve adsorption effect is best. The isothermal adsorption data of the system on 4A molecular sieves were measured and fitted well by the adsorption equation of Langmuir and Freundlich （correlation coefficients greater than 0.98）. The breakthrough curves in fixed-bed were also studied in different conditions such as grain diameter, initial concentration, bed height and volume flux. These results provide the reference for design of adsorption process. |
