PURPOSE:To obtain pure methanol gas having a high purity by surely removing oxygen contained in methanol vapor or in a gas containing the methanol vapor as an impurity without by-producing other impurities by the decomposition of the methanol., etc. CONSTITUTION:Methanol vapor alone or a methanol vapor-containing gas diluted with hydrogen, nitrogen or argon is brought into contact with a catalyst containing manganese oxide as a main component. If necessary, the catalyst may preliminarily brought into contact with methanol vapor before the purification process. |
