中文摘要	The potential of the sorbent-catalysts prepared from three low cost materials, i.e., the lime, fly ash and some industrial waste material containing iron oxide, have been investigated for simultaneous removal of SO2 and NOx from flue gas in the temperature range 700-850 degrees C. NH3 was chosen as the reducing agent for NO reduction in this study. Experimental results showed that SO2 and NO could be simultaneously removed efficiently in the absence of 0, at the temperature window of 700-800 degrees C. The effect of product layer generated from SO2 removal on NO removal was not obvious. NO removal efficiency was strongly inhibited by O-2, which was attributed to the partial oxidation of NH3 to NO over the sorbent-catalysts in the presence of oxygen. Neither NO2 nor N2O by-product was detected both in the absence and presence of O-2. Three routes were suggested to overcome the negative effect of O-2.
