Abstract
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.
