研究了沸石的处理方式、渗透蒸发体系的组成以及醇-水混合物中氢键的变化对Silicalite-I沸石填充聚二甲基硅橡胶膜渗透蒸发性质的影响.实验结果表明,沸石经水热处理以及在醇-水混合物中加入盐、酸等电解质能提高膜对醇-水混合物的分离性能.
The effects of the treatment mode of zeolite, the composition of pervaporation system and the hydrogen bonding in the alcohol-water mixture on the pervaporation properties of Silicalite-I zeolite filled with polydimethylsilicone rubber membrane were investigated.The experimental results show that the hydrothermal treatment of zeolite, In the alcohol - water mixture by adding salt, acid and other electrolytes can improve the membrane of the alcohol - water mixture separation performance.
