分别采用原位水热二次合成法、微波密闭合成法, 在管状α-Al2O3陶瓷管的外表面上合成出了一系列的NaA型分子筛膜,考察了四种原料配比、四种涂晶方法对合成分子筛膜的影响,对合成条件进行了优化. 分别采用XRD、SEM、及乙醇水溶液的渗透汽化实验(用氮气吹扫渗透侧作渗透推动力)对合成的膜进行了表征.结果表明当原料配比为Na2O∶Al2O3∶SiO2∶H2O=1∶1∶3.6∶100,清液涂晶种,微波密闭合成出的分子筛膜对水和乙醇的选择性较好,分离因子远远大于空白管的分离因子, 95%(wt)的乙醇水溶液通过膜

A series of NaA-type zeolite membranes were synthesized on the outer surface of tubular α-Al2O3 ceramic tubes by in-situ hydrothermal secondary synthesis and microwave closed synthesis methods, and the effects of four raw material ratios and four crystallization methods on the synthesis of zeolite membranes were investigated, and the synthesis conditions were optimized. The synthesized membranes were characterized by pervaporation experiments of XRD, SEM, and ethanol aqueous solutions (purging the permeable side with nitrogen as osmotic thrust). The results showed that when the ratio of raw materials was Na2O∶Al2O3∶SiO2∶H2O=1∶1:3.6∶100, the molecular sieve membrane synthesized by the clear liquid coating crystal seed and microwave sealing had good selectivity for water and ethanol, and the separation factor was much greater than that of the blank tube, and 95% (wt) of ethanol aqueous solution passed through the membrane
