- Abstract
The thermodynamic and kinetic performance of the oxidative absorbent S2O82‐/CaO2 for NO removal was evaluated. The results indicated that the optimal molar ratio of Na2S2O8/CaO2 was 0.1:0.2 mol/mol. The experimental results showed that the combination of Na2S2O8 and CaO2 had a positive synergistic effect on the NO removal. The results of the thermodynamic calculation verified that the use of the oxidative absorbent S2O82‐/CaO2 was effective for NO removal. The results of the kinetic study showed that the NO reaction was a 1.1‐order equation and the average activation energy of the reaction was 53.0 kJ/mol. The oxidative absorbent S2O82‐/CaO2 shows potential for the simultaneous wet removal of NO and SO2 with high efficiency, no secondary pollution, and low cost.
