The influence of working pressure on the mechanisms of the CO/H reaction on a co-precipitated CuO/ZnO/AlO catalyst have been studied at 230 °C and in the pressure range of 1-75 bar. In the CO hydrogenation using CuO/ZnO/AlO, the products were found to be CO, methanol and water almost exclusively. Only a trace of methane formation was observed. Methanol and carbon monoxide are competitively formed. The former is produced directly from CO whatever the pressure whereas carbon monoxide stems either from CO directly at high pressure or both methanol decomposition and CO directly at low pressure.
