摘　　要：采用水热合成法制备了一种USY/SAPO-5复合分子筛。通过XRDI、R、TEM等方法进行表征,分析其晶型结构,证实形成了以USY为核,以SAPO-5为壳的复合分子筛结构。并将USY/SA-PO-5复合分子筛应用于苯和长链烯烃的烷基化反应,在n(苯):n(长链烯烃)=8∶1,反应温度200℃,压力3.5 MPa,在此条件下长链烯烃的转化率可达99.2%,选择性也达到最好。LISY/SAPO-5 composite molecular sieve catalyst was synthesized by hydrothermal method and characterized by XRD, IR,TEM,and other methods. Analysed its crystal structure, confirmed the formation of a nuclear-shell （USY/SAPO-5）structure of the compound. And applied it to alkylation of benzene and long chain alkylation,the optimum reaction condition was attained as follows：n（benzene） ： n（long-chain olefin） = 8 ： 1, reaction temperature 200℃,and reaction pressure 3.5 MPa, the conversion of long-chain olefin was reached 99.5 %.
