Development of De-NO_x selective catalytic reduction catalyst using V_2O_5 -TiO_2 supported on a ceramic filter candle

摘要

This study reports the development of a V_2O_5-TiO_2-based selective catalytic reduction (SCR) catalyst supported on alumina-silicate water filter candles for NO_x abatement. The synthesised catalysts have been characterised by thermogravimetry/differential scanning calorimetry, X-ray diffraction, scanning electron microscope and measurement of NO_x removal performance. The catalyst synthesised under optimal conditions shows NO_x reduction efficiency of ＞97%. SCR performance has been augmented using O_2 as a carrier gas. This simple, reproducible procedure can have wide applications in NO_x abatement.
