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℃.
