The removal of SO2 and NO from flue gas could be achieved with high efficiency by using activated semi-coke through catalytic oxidation. In order to probe the interaction between SO2 and NO on the surface of activated semi-coke, the TPD study was carried out when NO and SO2 had adsorbed separately on the support surface or they were brought into the reaction of TPD simultaneously. The results showed that the activated semi-coke had two different alkaline adsorption sites and the surface of semi-coke was heterogeneous due to the appearance of overlap peak. What’s more, SCO process by using activated semi-coke should be placed after the process of desulfurization.
