Abstract：In order to reduce the emission of SO2 and[NOx]in the iron ore sintering， the desulfurization and denitration of iron ore sintering flue gas based on ammonia-activated carbon process was developed. The results show that more than 70% denitration rate was obtained using activated carbon after SO2 was removed by ammonia process. The denitration mechanism is that the escaping NH3 reacted with C-OH in the surface of activated carbon to produce the N2 and H2O. For the sintering plants using ammonia desulfurization process， more than 99% desulfurization rate and 70% denitration rate were achieved just connecting a single stage activated carbon adsorption tower after the desulfurization spray tower， which could reduce the capital cost and also solve the secondary environmental pollution due to the NH3 escape.
