ZSM-5沸石/硅胶复合催化材料的制备
摘要：
一种用原位晶化方法合成的ZSM-5沸石/硅胶复合催化材料的制备方法是：将任意颗粒大小的硅胶与铝源、钠源、有机胺模板剂、水组成的溶液或悬浮液混合，搅拌均匀，加热至130～190℃晶化反应10小时至8天，洗涤、过滤，干燥。该复合材料中ZSM-5沸石的含量可在5～80重量％的范围内调变。该方法使沸石牢固地分散于基体颗粒表面，提高了小晶粒沸石在基体上的稳定性，并解决了通常合成小晶粒沸石过程中过滤的困难。
摘要（英）：

Process to synthesize ZSM-5 zeolite/silica gel compounded catalyst by in-situ crystallization features that it is made up through mixing granular silica gel with the solution or emulsion of Al source, Na source, organic amine and water, heating to 130-190 deg.C, crystallizing for 10 hours-8 days, washing, filter and drying. Its ZSM-5 zeolite content may be adjustable in the range of 5-80 Wt%. Zeolite grains are firmly dispersed on the surface of basic particles to increase the stability of zeolite grains on basic body.
