Performance of Cu-Based Catalysts in Low-Temperature Methanol Synthesis

Abstract:

The reactions of the methanol synthesis were conducted from the CO/CO₂/H₂ on the Cu-based catalysts using different solvent at 443 K and 3.0 MPa. The alcohol solvent had the activity in the low-temperature methanol synthesis reaction. The activity of the Cu-based catalyst with ZnO as carrier was higher than that of the catalyst with CeO₂, Al₂O₃, or TiO₂ as carrier separately in the reaction. The addition of the CeO₂ to the Cu/ZnO catalysts improved the copper species dispersion, so that it was easier for the reduction of the Cu/CeO₂-ZnO catalyst than that of the Cu/ZnO catalyst according to the TPR analysis. The variation trend of the BET surface area and the copper surface area was consistent with those of the activity for the Cu/ZnO and the Cu/CeO₂-ZnO catalysts in the reaction. The activity of the Cu/CeO₂-ZnO catalyst was higher than that of the Cu/ZnO catalyst in the reaction.
