Abstract: Membranes of ZSM-5 zeolite were obtained by one step in situ hydrothermal synthesis. XRD and SEM micrographs were used to characterize these membranes. The membranes were used for the separation of ethanethiol from n-hexane. It was shown from the result that：the desulfurizing effect decreased with increasing permeation rate；and the rejection performance was enhanced after the membranes were loaded with Cu2+. However，high concentration of Cu2+ decreased the permeation rate. It was also found that at a higher operation temperature，the permeation rate increased while the desulfurizing effect decreased.

摘要： 采用一次水热合成法，制得ZSM-5分子筛膜，用XRD和扫描电镜对膜的物理及化学结构进行了分析表征。所制得的膜用于正己烷中硫醇的脱除，研究了不同膜通量、负载离子浓度和料液温度对膜性能的影响。结果表明：渗透通量大，对硫醇的脱除不利；铜离子的引入大大提高了分子筛膜管的截留性能，但负载铜离子过高会降低模拟汽油的通量；操作温度升高，渗透通量增加，膜对硫醇的脱除率下降。
