一种超细粒子沸石芳构化催化剂及其制备方法和应用
摘要：
本发明公开了一种超细粒子沸石芳构化催化剂及其制备方法和在全馏分FCC汽油加氢精制/芳构化组合工艺中的应用。以催化剂的重量为基准，该催化剂的组成包括：过渡金属氧化物和镧系稀土金属氧化物含量之和为1.0wt％～10.0wt％，超细粒子沸石含量为50.0wt％～90.0wt％，余量为无机氧化物粘合剂，超细粒子沸石的晶粒度为20nm～800nm。由于该超细粒子沸石芳构化催化剂总酸量低，特别是L酸量较低，孔道更加畅通，因此，该催化剂抗结焦能力强，稳定性好，而且能在降低FCC汽油的硫含量和烯烃含量的同时，保证所得汽油产物的抗爆指数((R+M)/2)损失较小。
摘要（英）：

Preparation of micro-size particle zeolite catalyst for aromatization and its application in complete fractional FCC gasoline hydrogenation-aromatization composite process are disclosed. The catalyst consists of: transition metal oxide and lanthanide metal oxide is 1.0wt% - 10.0wt%, micro-size particle zeolite of 20nm-800nm 50.0wt% - 90.0wt%, and balanced inorganic oxide binder. Its advantages include low total and L acidity, unblocked pore canal, good stability and strong anticoking ability, low antiknock index ((R+M)/2) loss of gasoline product with reduced S and olefin contents of FCC gasoline.
