【摘要】 采用水热合成法在Ａｌ２Ｏ３陶瓷载体和ＳｉＯ２复合膜上成功地合成了ＺＳＭ－５沸石膜．考察了ＺＳＭ－５沸石膜合成中载体性质、合成溶液的碱度、水硅质量比、晶化时间等对成膜的影响，探讨了沸石膜的生成机理．并对合成的沸石膜进行了ＸＲＤ及ＳＥＭ表征，表明当合成液水硅质量比为１００时，主要是液相晶化机制起作用，表面的Ｓｉ－Ｏ键或Ａｌ－Ｏ键参与晶化，使膜与载体紧密结合．更多还原

【Abstract】 ? ZSM 5 membrane has been synthesized on the supports of Al 2O 3 ceramic and SiO 2 composite membrane with hydrothermal synthesis. The effects of synthesis factors, such as the properties of supports, alkaline, m (H 2O)∶ m (SiO 2), crystalline time are thoroughly investigated. Furthermore, the prepared membrane has been characterized by XRD and SEM. The results indicate that the crystalline mechanism of liquid phase acts as essentially when H 2O and SiO 2 mass ratio in solution is 100. The Si-O or Al-O bone of the surface participates in crystalline so that membrane was bound with the support tightly.更多还原
