Adsorption has been studied on a three component methanol synthesis catalyst during the synthesis of methanol in a closed circulating system. It has been shown that the adsorption of hydrogen and carbon monoxide are both enhanced by the presence of the other. The composition of the adsorbed phase has scarcely been affected at all by the ratio of the partial pressure of hydrogen to carbon monoxide, and the formation of surface complex has been suggested. The rate-determining step of the synthesis of methanol has been suggested to be the process of the Eley-Rideal type hydrogenation of the surface complex.
