Impact of Carbon Dioxide on the Activity and Selectivity of Supported Palladium Catalysts for Carbon Monoxide Hydrogenation

Abstract

The introduction of 1.5 vol.% carbon dioxide into the reaction mixture (CO/H₂ = 1:2) is shown to accelerate the rate of formation of methanol and the selectivity towards oxygen-containing products over palladium catalysts supported on oxides of various chemical natures. The maximum degree of impact of CO₂ was observed over palladium supported on magnesia and zirconia.
