摘要: 研究了粒径为15μm和5μm的水热处理Silicalite-Ⅰ填充PDMS膜以及酸处理Silicalite-Ⅰ填充不同品种硅橡胶膜对低浓度乙醇-水混合物的渗透蒸发分离性能的影响。结果表明,沸石粒径的减小,不利于乙醇-水分离系数的提高;不同品种硅橡胶的沸石填充膜对乙醇-水的渗透蒸发分离性能与硅橡胶本身的性质有关。

Abstract: The separation properties of ethanol-water mixture through polydimethylsiloxane(PDMS)membranes filled with silicalite-Ⅰtreated under steam, in which the zeolite particle size is 15 μm and 5μm, as well as acid treated silicalite-Ⅰ filled with different type silicone rubber membanes have been studied.The results show that the decrease of zeolite particle size is not favourable to the selectivity of ethanol-water mixture and the separation properties of ethanol-water mixture through different type of silicone rubber membrane filled with acid leached silicalite-Ⅰare related to the property of silicone rubber itself.

Key words: Zeolite silicalite-Ⅰ, Silicone rubber membrane, Particle size, Type, Ethanol-water separation
