有支撑纯NaA和NaY沸石膜的合成

Synthesizing of Supported Pure NaA and NaY Zeolite Membranes

本文简要介绍有支撑纯ＮａＡ和ＮａＹ沸石膜的合成方法和结构分析结果。研究结果表明，通过对支撑体进行适当碱处理，用二次水热合成由适当组成的反应混合物可以在多孔陶瓷支撑体上合成堆积紧密的纯ＮａＡ和ＮａＹ沸石膜。

The synthesis process and results of structural analysis of supported pure NaA and NaY zeolite membranes are reported.The results show that pure NaA and NaY zeolite membranes firmly adhering to the supports can be prepared by twice hydrothermal synthesis with proper composition of precursors,on condition that the supports have been treated by alkali solution and thoroughly washed.
