| Abstract: |
| The MnOx/TiO2 and CeOx-MnOx/TiO2 catalysts for low temperature selective catalytic reduction (SCR) denitrification were synthesized by ultrasonic impregnation method and characterized by SEM, EDS, BET and XPS. On this basis, the low-temperature SCR denitrification performances of the catalysts were studied, and effects of Mn loading amount and Ce/Mn molar ratio on the catalyst performance were investigated. The results show that when Mn loading amount is 15%, the catalyst has high catalytic activity. The doping of Ce is beneficial to improvement of catalytic activity of the catalyst. When Ce/Mn is 0.8, the catalyst has the highest catalytic activity, which reaches 97.86% at 180 ℃. Ce doping is beneficial to improve the sulfur and water resistance of the catalyst, but it still needs to be further improved. |
