The present study describes the performance of H/ZSM-5 catalyst modified with different ZnO contents for the conversion of methanol to aromatics. The contribution of zinc ions was evaluated by analyzing the acid site density, specific surface area, pore structure, and so on, of ZnO/ZSM-5 catalysts. The results showed that the catalytic activity reached a maximum when the content of ZnO was 8 wt%, and the total product yield could reach 56.2%, of which aromatics accounted for 95 wt%.
