Catalytic performance and hydrothermal durability of CeO sub(2)-V sub(2)O sub(5)-ZrO sub(2)/WO sub(3 )-TiO sub(2) based NH sub(3)-SCR catalysts

Ceria modified V sub(2)O sub(5)-ZrO sub(2)/WO sub(3)-TiO sub(2 ) catalysts with different Ce loading (0, 5, 10 wt%) have been evaluated in the NH sub(3)-SCR process before and after hydrothermal aging (750 degree C, 10 wt% H sub(2)O/air for 12 h). Compared with only Zr containing catalysts, addition...
