Abstract: The research on the anti-sulfur denitration catalysts at home and abroad in recent years is reviewed from the impacts of sulfur poisoning mechanism,selection of carrier and preparation methods on the anti-sulfur performances of denitration catalysts.It is concluded that sulfates and metal sulfation are the main reasons causing denitration catalysts to be poisoned.The desulfurization catalysts with high anti-sulfur performances have typically characteristics such as more acid sites,suitable pore size and so on.Finally,the future development of anti-sulfur denitration catalyst is prospected.
