A series of ZnZSM-5 zeolites with hierarchical pores were prepared by a seed-induced method with the addition of cetyltrimethylammonium bromide (CTAB). The influence of the amounts of CTAB on the physicochemical properties of the zeolites was investigated by XRD, FTIR, SEM, TEM, N₂ adsorption and desorption, ICP-OES, XPS, NH₃-TPD and TG analysis. The results showed that Zn was partially incorporated in the zeolite framework; the addition of CTAB in the synthesis reduced the primary crystal size of the zeolite, but increased the specific surface area and mesopore volume. The catalytic performance of the prepared zeolites was evaluated for methanol to aromatics reaction in a fixed bed reactor. The lifetime of the catalysts was greatly enhanced by the addition of CTAB in the synthesis. The incorporation of Zn increased the selectivity of aromatics.

通过种子诱导的方法，添加十六烷基三甲基溴化铵（CTAB），制备了一系列具有分级孔的ZnZSM-5沸石。通过XRD，FTIR，SEM，TEM，N ₂吸附和脱附，ICP-OES，XPS，NH ₃考察了CTAB含量对沸石理化性质的影响。-TPD和TG分析。结果表明，Zn部分地掺入了沸石骨架中。在合成过程中添加CTAB可以减少沸石的初生晶体尺寸，但会增加比表面积和中孔体积。评价了在固定床反应器中制备的沸石对于甲醇与芳族化合物反应的催化性能。通过在合成过程中添加CTAB，大大提高了催化剂的使用寿命。Zn的引入增加了芳族化合物的选择性。
