Open publisher page 1 citations

Abstract

Intrinsic kinetics of dimethyl ether synthesis from CO_2 hydrogenation over Cu-ZnO-Al_2O_3/HZSM-5 bifunctional catalyst was studied in a fixed-bed integral reactor.Effects of residence time, H_2/CO_2 molar ratio, reaction temperature and pressure on the concentration of CO_2, dimethyl ether, methanol and CO in the product gas were discussed. This study had provided a series of kinetic data for the synthesis of DME from CO_2 hydrogenation.
