Comparative study of low temperature denitration performance of Mn-Ce/ACFA-TiO2 catalysts under oxy-fuel and air-fuel combustion flue gases

Xiang Gou, Ruiping Zhang, Guoyou Xu, Dong Zhao

Low temperature selective catalytic reduction (SCR) catalysts were prepared by using acetic acid modified fly ash (ACFA) and TiO2 with the loading of Mn-Ce. The powder catalysts were characterized by BET, XRD and SEM. The effects of Mn-Ce molar ratio on the NO conversion of SCR catalyst were investigated under different atmospheres of N2 and CO2, respectively. The 8% Mn-Ce/ACFA-TiO2 catalyst with Mn-Ce molar ratio of 1:1 showed good performance of NO conversion at 300 °C, 84.28% in N2 atmosphere and 74.29% in CO2 atmosphere. N2O was observed in the experiments of 8% Mn/ACFA-TiO2, 95.3 ppm in N2 atmosphere and 103.6 ppm in CO2atmosphere, respectively.
