MgO/HZSM-5 Catalysts for the Dehydration of Methanol to Dimethyl Ether

Liu Cui-gai

Open publisher page 2 citations

Abstract

MgO/HZSM-5 catalysts were prepared by dipping technique.Activities of the catalysts were examined and structure of the catalysts was characterized by XRD,BET and NH3-TPD.Results showed that the prepared catalyst had good activity and selectivity for methanol dehydration to dimethyl ether.In the reaction temperature of 260 ℃ and space velocity of 1 500 h-1,the catalyst had the best catalytic performance.
