| Abstract: | Manganese-based catalysts exhibit excellent catalytic activitiy for low-temperature NOx selective catalytic reduction with ammonia(NH3-SCR).Water and sulfur dioxide in the reaction stream are prone to severely inhibit activity of Mn-based SCR catalysts.The effects of H2O and SO2 on the activity of Mn-based SCR catalyst were discussed.Latest researches on enhancing the resistance of Mn-based catalysts to H2O and SO2 poisoning by modification,introducing promoters and optimizing the supports were reviewed,and the trends in further researches were outlined. |
