Characterization and Catalytic Performance Study of CuO-ZnO-ZrO₂-TiO₂ Catalyst for Methanol Synthesis from Carbon Dioxide Hydrogenation

Abstract:

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 CuOis 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^-1with a H₂/CO₂molar 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.
