【摘要】 用水热法在多孔钛片上原位合成沸石分子筛Silicalite(S-1)膜。系统地考察了硅溶胶浓度、溶液pH值、晶化时间和晶化温度对成膜的影响;结合样品的XRD和SEM图谱,确定了最佳的制备条件。将制得的S-1膜用于乙醇水溶液渗透汽化,测定了醇/水分离的渗透通量和分离因子。结果表明,S-1膜对乙醇水溶液有良好的浓缩作用。

【Abstract】 Silicalite1(S1) membranes supported by porous titanium plate were prepared via hydrothermal syntheses insituThe affects of the concentration,the pH of solution and the time,the temperature of crystalline on formation of S1 membrane were investigatedThe technical parameters of preparing S1 membrane were evaluated together with the charaterization by XRD and SEM spectraThe flux and separation factor of ethanol/water solution were measured in pervaporation for S1 membraneThe results showed that remarkble concentration of ethanol was obtained
