Abstract: In this paper, the influence factors, such as the treated methods of zeolite, the composition of feed and the change of hydrogen bond in feed have been studied on silicalite-Ifilled PDMSmembranes.The results show that pretreating zeolite under steam and weakening the intensity of hydrogen bond in alcohol-water mixture by adding electrolytes such as salt and acid can improve the separation properties of the membranes signifcantly.

Key words: Silicalite-I zeolite, PDMS membrane, Filling, Pervaporation, Influence factor
