How does the catalytic reaction for methanol synthesis proceed? Answer: Whether it is zinc, chromium catalysts or copper-based catalysts, the methanol reaction is identical as a multiphase catalytic process. This complex process proceeds through the following five steps: 1) Diffusion—gas diffuses from the gas phase to the gas-catalyst interface. 2) Adsorption—Various gas components undergo chemical adsorption on the active surface of the catalyst. 3) Surface reaction—Gases in chemical adsorption react according to different kinetics to form products. 4) Desorption — the release of reaction products. 5) Diffusion — The reaction products diffuse from the gas-catalyst interface into the gas phase.
