Abstrakt: A study is performed of the catalytic properties of Cu–Zn catalysts on Al2O3 and SiO2 supports (Acros) in the reaction of CO2 hydrogenation to obtain methanol. A sample of 30Cu15Zn/Al2O3 displays great selectivity toward methanol. A sample of 30Cu15Zn/SiO2 has the highest methanol performance. The methanol performance of a sample of 10Cu5Zn/Al2O3 is doubled when the pressure is raised from 10 to 30 atm, and a 94% increase in selectivity is observed. A sample of catalyst 10Cu5Zn/SiO2 does not lose its activity after 10 h of a catalytic reaction, and its methanol performance grows with repeated use. [ABSTRACT FROM AUTHOR]
