Method for adsorption treatment of gas

摘要

A method is disclosed for adsorption treatment of a gas which involves moving an adsorbent through a zone to alternately carry out a gas treating step by passing a gas containing a predetermined material such as a harmful organic solvent to be treated through the adsorbent to adsorb the material onto the adsorbent and a regenerating step by passing a regenerating gas at a high temperature through the adsorbent to desorb the adsorbed material from the adsorbent, while feeding the regenerating gas containing the desorbed material to the adsorbent after the gas treating step but before the regenerating step to re-adsorb the material onto the adsorbent before it reaches the regenerating step.
