摘要： 以不锈钢金属网为载体, 采用预涂晶种的二次生长法, 在水热条件下制备了连续、无明显缺陷的X型分子筛膜. 考察了反应物中水的含量、碱度、硅铝比和反应时间等制备条件对形成X型分子筛膜的影响,  优化了X型分子筛膜的制备条件,  利用扫描电子显微镜(SEM)对不同反应条件下制备的X型分子筛膜的形貌进行了观察, 并对结果进行了分析.

关键词: X型分子筛膜, 水热制备, 硅铝比

Abstract: The synthesis of X-type zeolite membrane was studied in the hydrothermal conditions. A secondary growth method with the pre-seed step was used by choosing the stainless steel net as the support. Different reaction conditions were adjusted for the preparation of X-type zeolite membrane, such as the quantity of water, alkalinity, Si/Al ratio and the reaction time. Scanning electron microscopy technique was employed to observe the morphology of X-type zeolite membranes. Finally, the best synthesis conditions were found after the comparison and analysis of these results, better morphology without obvious defects X-type zeolite membranes were then synthesized.

Key words: X-Type zeolite membrane, Hydrothermal preparation, Si/Al ratio
