- A series of high concentration of vanadium catalysts were prepared by the citric acid method and was evaluated for the selective catalytic reduction of NOx by ammonia (NH3-SCR) at middle-low temperature (180-280oC). Experimental results showed that V-W/SiTiOx exhibited the good activity on NH3-SCR reactions, N2 selectivity and SO2 durability over a broad temperature range of 180-280oC with the high space velocity. Above 90% conversion of NOx with 100% selectivity of N2 had been achieved on V5W8SiTi at 220-240oC with the space velocity of 36,000 h-1. X-ray diffraction, BET were adopted for the characterization of the active phase. The high activity of the VW/SiTi mixed oxide catalyst could be main be reason for the strong interaction between V and W.
