Abstract: The research status of desufurizers at a low temperature is reviewed. The desulfurization mechanism，kinetic models and regeneration methods for the single desulfurizer of activated carbon，ferric oxide and zinc oxide used at a lower temperature are summarized. The factors that affect the removal of hydrogen sulfide，including structure of desulfurizer，composition of feed gas and process conditions are discussed. The progress in the research of complex desulfurizers and commerical application are also summarized. The research prospect of desulfurizers at a low temperature is presented.
