Abstrakt: The reaction pathway of high-pressure CO2hydrogenation over a Cu/ZnO/Al2O3catalyst is investigated through the gradients of reactants/products concentration and catalyst temperature within the catalytic reactor. This study reveals that methanol is formed through direct CO2hydrogenation at low temperature, while above 260 °C methanol formation is mediated viaCO which is formed by reverse water–gas shift reaction.
