Reduction of NOx with Ethanol over Copper-supported Catalysts
Abstract:
Ethanol was used as a reducing agent instead of NH3 for the removal of NOx.A series of Copper-supported catalysts were prepared via impregnation method.The effects of temperature and the support were studied.The reduction activity and texture of the catalysts were examined by TPR and BET methods.It was found that 10% CuO/TYZp-3 exhibited good catalytic activity at high temperatures,and the NOx conversion reached 98.7% at 350;and 10% CuO/20% TiO2-γ-Al2O3 showed good catalyic activity at low temperatures,and the NOx conversion reached 46.4% at 250℃.And at above 400℃,the NOx conversion over other CuO catalysts reached 99%.
