| Abstract: | CuO-ZnO-Al2O3/ZSM-5 and CuO-ZnO-Al2O3-Cr2O3/ZSM-5 catalysts were prepared for the dehydration of methanol to dimethyl ether （DME）. The micro-counter-chromatograph onlined by the catalyst for activity evaluation, the catalysts were characterized by XRD. In this experiment, the highest activeness of the catalyst is obtained at Cuo ：ZnO= 1 ： 1, the precentage of Cr in the catalyst is 1%, calcined at 350℃. |
