ZSM-5沸石分子筛是一种含有机胺离子的高硅铝比的铝硅酸盐晶体。它具有许多独特的催化性能,可应用于异构化、烷基化、歧化、芳构化、选择性裂化、油品改质等反应过程。尤其对二甲苯异构化、乙烯和苯的烷基化、甲苯歧化等反应,ZSM-5沸石具有优异的活性、选择性和稳定性,因此在国外已应用于工业生产。我们曾用乙胺、异丙胺或正丁胺作有机胺原料,添加晶种,在静止或慢速搅拌下晶化,得到 ZSM-5沸石,并对其催化活性进行
ZSM-5 Zeolite Molecular Sieve is a kind of aluminosilicate crystal containing organic amine ions with high Si / Al ratio. It has many unique catalytic properties, can be applied to the isomerization, alkylation, disproportionation, aromatization, selective cracking, oil modification reaction process. Especially for xylene isomerization, ethylene and benzene alkylation, toluene disproportionation reactions, ZSM-5 zeolite with excellent activity, selectivity and stability, it has been applied abroad in industrial production. We have ethylamine, isopropylamine or n-butylamine as organic amine raw materials, adding seed crystals, crystallized under still or slow stirring to obtain ZSM-5 zeolite, and its catalytic activity
