| Abstract: | A CuO-ZnO-Al2O3/HZSM-5 catalyst for synthesis of dimethyl ether from CO2/H2 was prepared using ethanol as solvent and oxalic acid as precipitator. At 245℃, 2.2MPa, 2400h－1 and H2/CO2 of 2.79, CO2 conversion of 22.61%, selectivity to dimethyl ether of 45.90%, selectivity to methanol of 14.81% and yield of oxo-compounds (CH3OH+CH3OCH3) of 13.73% were obtained. Preliminary investigation into reaction condition and activity stability of the catalyst were made. |
