Experimental Research on Catalysts of V₂O₅/AC and V₂O₅/CNTs for Low Temperature SCR Denitrification

Abstract:

Two catalysts (V₂O₅/AC and V₂O₅/CNTs) with different loadings, prepared by impregnation method, were used to research the DeNOx activity under N₂ and CO₂ atmospheres respecitively at the temperature range from 100°C to 300°C using a fixed bed reactor. Effects of temperature, loading and support on the DeNOx activity were studied. The results show that the NO conversion of the both catalysts increases with the reaction temperature. The loading and support have significant effects on the activities. 9%V₂O₅/AC and 9%V₂O₅/CNTs yielded 80% and 66.6% NO conversion at 250°C respectively under N₂ atmosphere, however, they yielded 78.1% and 75.1% respectively under CO₂ atmosphere.
