采用NaOH溶液处理法制备了介孔ZSM-5分子筛。采用包埋法合成了ZSM-5/SAPO-34复合介孔分子筛，并采用X射线衍射图谱（XRD）、电子扫描电镜（SEM）、氮吸附进行分析，在固定床反应器中进行了甲醇芳构化反应。研究结果表明，ZSM-5/SAPO-34复合分子筛孔径呈微孔和介孔多级孔分布，孔径和孔容均高于ZSM-5分子筛。当ZSM-5与SAPO-34分子筛的质量比为1：2时，ZSM-5/SAPO-34复合分子筛具有较好的芳构化活性。在反应温度为475℃、反应压力0.5 MPa、空速（ LHSV）1.2 h-1条件下，BTX（苯、甲苯和二甲苯）的收率可达30.8%。

ZSM-5 Mesoporous molecular sieve were prepared by NaOH solution to alkali treatment of ZSM-5 molecular sieve,ZSM-5/SAPO-34 mesoporous composite molecular sieves were prepared by em-bedding method. The samples were characterized by X-ray diffraction( XRD),scanning electron micro-scope( SEM)and N2 sorption. Methanol aromatization reaction were accomplished in fixed bed reactor. The results showed that the pore diameter of ZSM-5/SAPO-34 is a multistage aperture of microporous and mesoporous,the pore size and pore volume is higher than the ZSM-5 molecular sieve. When ZSM-5 and SAPO-34 molecular sieve ’s mass ratio is 1:2 ,the ZSM-5/SAPO-34 mesoporous composite molecular sieves has better aromatization activity. In reaction temperature 475 ℃,pressure is 0. 5 MPa,air speed (LHSV)1. 2 h-1,under the condition of BTX(benzene,toluene and xylene)and the yield can reach 30 . 8%.
