Abstract

This work investigates the effect of addition of Fe2O3 in FeVO4 supported on TiO2–WO3–SiO2 TWS NH3–SCR catalysts The catalysts were prepared by loading 84 wt FeVO4 and different amounts of Fe2O3 on TWS support and the effect of ageing in the range of temperature 650–750 °C on the SCR reaction was studied Fe2O3 does not give any significant contribution to SCR activity for the samples treated at lower temperature but a remarkable difference is achieved for the samples aged at 750 °C The presence of Fe2O3 at an appropriate loading significantly enhances the thermal stability of the system by contrasting the formation of rutile and lowering the formation of surface VOx species
