ZSM-5分子筛及其制备方法
摘要：
本发明提供一种薄板型ZSM-5分子筛的制备方法。该方法是在制备凝胶的过程中，将硅源、铝源、模板剂及添加剂混合，在10～50℃下搅拌1～20h；在10～90℃下静置陈化10～30h；将制备好的凝胶反应混合物放入反应釜中，再将反应釜放入烘箱中，在100～220℃下晶化4～30h，取出过滤、洗涤、干燥后得到ZSM-5分子筛产品。本发明在类固相条件下合成出ZSM-5分子筛，且得到ZSM-5分子筛产品形貌为薄板型，相对结晶度90～110％、SiO2/Al2O3摩尔比≦100。
摘要（英）：

The invention provides a preparation method of a sheet ZSM-5 molecular sieve. The method includes: in a gel preparation process, mixing a silicon source, an aluminum source, a template agent and an additive, and performing stirring at 10-50DEG C for 1-20h; conducting standing aging for 10-30h at 10-90DEG C; putting the prepared gel reaction mixture into a reaction kettle, then putting the reactionkettle into an oven, conducting crystallization at 100-220DEG C for 4-30h, then taking the product out, and carrying out filtering, washing and drying to obtain the ZSM-5 molecular sieve product. Themethod provided by the invention synthesizes the ZSM-5 molecular sieve under a solid like phase condition, and the obtained ZSM-5 molecular sieve product is sheet shaped, and has a relative crystallinity of 90-110%, and an SiO2/Al2O3 molar ratio of less than or equal to 100.
