Y/EU-1/ZSM-5/ASA/杂多酸复合材料及其制备方法
摘要：
本发明提供了一种含有规则介孔Y/EU‑1/ZSM‑5/ASA/杂多酸复合材料的制备方法，包括：先合成导向剂，采用水热晶化法合成小晶粒Y型分子筛，然后在含分子筛的浆液中加入表面活性剂、EU‑1与ZSM‑5分子筛浆液、碱性铝源溶液，产物经洗涤、干燥、焙烧，即得介孔Y/EU‑1/ZSM‑5/ASA复合材料。然后在H3PMo12‑X‑YWXLaYO40·nH2O杂多酸水溶液中加入表面活性剂，并与Y/ASA材料混合打浆，老化处理，干燥后即得介孔Y/EU‑1/ZSM‑5/ASA/杂多酸复合材料。
摘要（英）：

The invention provides a method for preparing a Y/EU-1/ZSM-5/ASA/heteropolyacid composite material containing regular mesopores. The method comprises the following steps: synthesizing a guiding agent, synthesizing small-grain-size Y-shaped molecular sieve by adopting a hydrothermal crystallization method; adding surfactant, EU-1 and ZSM-5 molecular sieve slurry and alkaline aluminum-source solution into the slurry containing a molecular sieve; washing, drying and roasting the product to obtain a mesoporous Y/EU-1/ZSM-5/ASA composite material; and adding a surfactant into an H3PMo12-X-YWXLaYO40.nH2O heteropolyacid, mixing and pulping with a Y/ASA material, aging and drying to obtain the mesoporous Y/EU-1/ZSM-5/ASA/heteropolyacid composite material.
