中文摘要：
对异丙醇中微量水在4A分子筛上的吸附性能进行了研究。对该体系的吸附平衡数据进行了测定，并用Langrnuir、Freundlich模型进行拟舍且吻合较好；采用Crank单孔模型对测定的吸附动力学数据进行拟合，得到了290K时的有效扩散系数De=3．539×10^-8cm^2／s,采用固定床测定了不同床层高度、不同流量及不同初始浓度下的动态透过曲线；这些结果为吸附工艺设计提供了基础数据。
英文摘要：
The adsorption characteristics of small amount of water in isopropanol （IPA） on 4A molecular sieves were studied in this paper. The isothermal adsorption data of the system were measured and fitted well by the models of Langmuir and Freundlich. According to the kinetic data, the Crank rnonopore model was used to calculate the diffusion coefficients of the temperature at 290 K and the result was 3. 539× 10^-8 cm^2/s. The breakthrough curves in fixed-bed were also carried out in different conditions such as bed height, volume flux and initial concentration. These results provide the basis for design of adsorption process.
