The desulfurization of low-concentration sulfur dioxide in laboratory simulated flue gas and on-site metallurgical flue gas was carried out by activated carbon adsorption in combination with microwave desorption. In comparison with the results of desulfurization, the effect of gas impurities in on-site metallurgical flue gas on the performance of activated carbon adsorption and microwave desorption, as well as the consumption of activated carbon during the desorption process, was also studied. The results show that the gas impurities decrease the unit adsorption capacity by 28.73mg/g and increase the consumption of activated carbon by 0.25g, thus go against the adsorption of activated carbon. Moreover, the use of on-site flue gas as microwave carrier gas in the desorption process can benefit the accumulation of medium-or high-concentration SO2 from the desorption process which can be used to produce acids.
