Article Preview

CuO-ZnO-ZrO2-TiO2 catalyst was prepared by parallel-slurry-mixing-precipitation method combined with addition of surfactant. The catalyst characterizations were investigated by Nitrogen adsorption-desorption, XRD, SEM and EDS. Results show that the average pore diameter of the mesoporous CuO-ZnO-ZrO2-TiO2 catalyst is 3.754 nm, and dispersion of CuO is better on CuO-ZnO-ZrO2-TiO2 catalyst. Under the conditions of reaction temperature of 503 K, reaction pressure of 2.0 MPa, space velocity of 2100 h-1 with a H2/CO2 molar ratio of 3:1, the catalyst exhibited favorable activity for methanol synthesis from CO2 hydrogenation. The selectivity to methanol and the yield of methanol were 27.42% and 4.50%, respectively.
