A new process of low-temperature methanol synthesis from CO/CO2/H2 based on dual-catalysis has been developed. Some alcohols, especially 2-alcohol, were found to have high catalytic promoting
effect on the synthesis of methanol from CO hydrogenation. At 443 K and 5 MPa, the synthesis of methanol could process high
effectively, resulting from the synergic catalysis of Cu/ZnO solid catalyst and 2-alcohol solvent catalyst. The primary results
showed that when 2-butanol was used as reaction solvent, the one-pass average yield and the selectivity of methanol, in 40
h continuous reaction at temperature as low as 443 K and 5 MPa, were high up to 46.51% and 98.94% respectively. The catalytic
activity was stable and the reaction temperature was 80 K or so lower than that in current industry synthesis process. This
new process hopefully will become a practical method for methanol synthesis at low temperature. 相似文献
