Process for preparing arene selectivity by enhancing methanol aromatizatian and process for preparation of catalyst thereof

The invention relates to a process for preparing arene selectivity by enhancing methanol aromatizatian. The process uses methanol as raw material, compositely modifies HZSM-5 molecular sieve catalyst by active ions like Ga, Zn, Cu, Cr and Ag for catalyzing methanol aromatizatian, employs the fixed bed continuous process or the floating bed continuous process, wherein the reaction pressure is 0.1-3.5MPa; the reaction temperature is 380-500 DEG C; the space velocity of raw material liquid is 0.1-10.0 h; and N2 space velocity is 120-800 h. The advantages of the invention lie in collocation combination of mixing ion modification, and arene selectivity reaches to 70%.
