Carbon Dioxide Hydrogenation

A series of CuO-ZnO-CeO2-ZrO2/HZSM-5 catalysts were prepared and characterized by XRD, H2-TPR. CO2hydrogenation to DME was carried out in a fixed bed reactor to test the catalytic performance of Ce-modified CuO-ZnO-ZrO2/HZSM-5 catalyst under the condition of GHSV=1800 h-1, p=3.0 MPa and T=250°C. The results indicate that the added CeO2improved the performance of the bifunctional catalysts, the CO2conversion and DME selectivity were obviously improved. CuO-ZnO-CeO2-ZrO2/HZSM-5 catalyst with Ce to Zr molar ratio of 1/1 showed the highest activity for DME synthesis from CO2hydrogenation.
