Abstract: The research progress of removal of H2S on impregnated activated carbon is reviewed，and the mechanisms of the reaction are summarized. The factors that affect the reaction，including pore distribution，component of impregnant，surface properties of activated carbon and ash content，are discussed. The effects of relative humidity，the feed composition and temperature on the removal process are also discussed. The regeneration of spent activated carbon is briefly discussed. The prospect of the desulfurization method is presented.
