How many steps are there in the catalytic reaction process of methanol?
The methanol synthesis reaction is a gas-solid phase catalytic process that consists of five steps: (1) CO and H2 diffuse to the surface of the catalyst； (2) CO and H2 are adsorbed on the catalyst surface ； (3) CO and H2 undergo chemical reactions on the catalyst surface ； (4) Desorption of CH3OH from the catalyst surface ； (5) CH3OH diffuses into the gas phase. The third step proceeds more slowly, and the entire reaction process depends on the speed at which this step takes place; therefore, all factors that affect the reaction should be kept under conditions optimal for its progression.
