摘要： A method for continuously treating a gas using an apparatus with a catalyst bed housed therein comprises the steps of passing a subject gas through the catalyst bed to adsorb the adsorbable substances in the subject gas thereto; and passing a regenerating gas through the catalyst bed adsorbed by the adsorbable substances in the subject gas to react and decompose them and simultaneously regenerate the catalyst bed. A particular apparatus is used with this method.By carrying out this method of the present invention using the gas treating apparatus, it is possible to continuously, efficiently and economically advantageously treat a gas containing a malodorous component, harmful component, organic solvent, hydrocarbon vapor or the like.
