The catalytic behavior of H-ZSM-5 and Zn/H-ZSM-5 for the aromatization of dimethyl ether (DME) was investigated. The increase in the number and strength of acid sites on the H-ZSM-5 zeolite was beneficial for DME aromatization. Aromatization performance was enhanced by loading Zn into H-ZSM-5. The yields of total and C_8 aromatics over H-ZSM-5 at 360℃ were 50.0% and 28.6%, respectively, and over Zn/H-ZSM-5 (Zn 2% in mass) were 66.2% and 39.0%, respectively. At 480℃, the total aromatics yield increased to 78.0%over Zn/H-ZSM-5.
