Abstract: Adsorption and reaction of CO on methanol synthesis catalyst have been studied with the pressure dynamic analysis equipment, The results show that the adsorbed CO on catalyst can be distinguished as reversibly adsorbed CO and irreverrsibly adsorbed CO. The irreversibly absorbed CO is necessary for the formation of CO_2, CH_4, etc. The formation of methanol is related with reversibly adsorbed CO. If there is not irrveer-sibly adsorbed H_2 on methanol synthesis catalyst, the catalyst has not methanol for-ming activity, and cannot adsorbs CO. So the part of irreversibly adsorbed H_2 which can be replaced by CO may be necessary for the adsorbed CO. The other part of irreversibly adsorbed H_2 which can not be replaced by CO may acted as a promoter of the catalyst.
