초록
NOx from the thermal power plants are NO and NO2. This work investigated the chemical/physical characteristics and SCR efficiency of newly prepared catalysts including tungsten (WO3), molybdenum (MoO3) and antimony (SbO3) based on vanadia(V2O5) over titania(TiO2). As a result of the examination, the surface area of the catalysts promoted with additional metals was larger and the de-NOx efficiency also was enhanced with temperature. The most efficient catalytst was V2O5/TiO2-WO3(10%) at 200 °C. Such a high efficiency could contribute to reduce the ammonia slip.
