Abstract

The effect of various modifiers on the performance of a commercial Cu/ZnO/Al2O3 catalyst in methanol synthesis from CO2/H2 and CO/H2 at 523 K and 30 bar has been studied. Several modifiers improved significantly the rate of methanol formation from CO2/H2, while all modified catalysts showed decreased rates for the synthesis from CO/H2 in comparison with the unmodified Cu/ZnO/Al2O3 catalyst. The synthesis rates from both CO2/H2 and CO/H2 correlated with the oxygen coverage of copper surface measured after the reaction by N2O titration.
