The influence of S02 inlet concentration, gas space velocity, adsorption temperature and O2 and H2O in flue gas has been systematically studied by using activated carbon as adsorbent. The adsorption capacity of activated carbon modified in different conditions and of some industrial solid wastes has been tested. At the same time, the mechanisms of the oxidation of SO2 over activated carbon surface have been analyzed, and fixed bed adsorption model has been set up.
