PURPOSE:To condense acetone and water and to remove these to the outside of a system and to economically regenerate zeolite by bringing zeolite used in dehydrating treatment of hydrated acetone into contact with heated inert gas circulating a cosed system. CONSTITUTION:Zeolite used in dehydrating treatment due to an ordinary method of hydrated acetone which is generated in various chemical industries is brought into contact with inert gas such as nitrogen and carbon dioxide in the specified pressure exceeding the atmospheric pressure, for example, about 0.1-20kg/cm<2>G preferably about 0.1-5kg/cm<2>G in about 0.1-5m/sec preferably about 0.1-2m/sec linear velocity expressed interms of a standard state while circulating it by means oft a blower 4. In such a way, acetone and water are desorbed to economically regenerate zeolite.
