Synergetic effect on selective catalytic reduction of NOx with NH3 over overloaded W and Ce on V2O5/TiO2 catalysts |
| 초록 |
W and Ce are known to be a good promoter to improve selective catalytic reduction (SCR) activity for V2O5/TiO2 catalysts. This work aimed at finding the optimum ratio and loading of promoters (W and Ce) on V2O5/TiO2 catalyst in order to improve SCR reactivity in low temperature region and to minimize N2O formation in high temperature region. It was found that W and Ce overloaded V2O5/TiO2 catalyst such as W/Ce/V/TiO2 (15:15:1 wt%) showed the most remarkable DeNOx properties over the wide temperature region. Additionally, this catalyst significantly suppressed N2O formation during SCR reaction, especially in high temperature region (350 - 400oC). Based on the characterization results, it was found that such superior activity originated from the improved reducibility and morphology of W and Ce species on V2O5/TiO2 catalyst when they are incorporated together at high loading. |
