摘要
通过文献调研,分析了不同元素表面修饰对分子筛酸性、孔结构及分布、硅铝比等物理性质,以及对其烃类催化裂化氢转移反应活性、选择性的影响,探讨了分子筛表面修饰在降低催化裂化汽油烯烃含量方面的积极作用。
Through the study of associated technical information, the impact of modification elements on the zeolite acidity, zeolite pore structure and distribution, Si-Al ratio, activity and selectivity of hydrogen transfer reaction are analyzed. The positive aspect of modification of zeolite in FCC gasoline olefin reduction was discussed.
