在这项工作中，研究了氧化钒对活性炭（AC）负载的铁基催化剂在氨（NH₃ - SCR）选择性催化还原氮氧化物中的影响。通过共浸渍法制备了一系列钒改性的Fe₂O₃/AC催化剂。
The effect of vanadium oxide on an iron-based catalyst supported on activated carbon (AC) in the selective catalytic reduction of NOx by NH3 (NH3-SCR) was investigated in this work. A series of vanadium-modified Fe2O3/AC catalysts were prepared by a coimpregnation method. The addition of a small amount of vanadium oxide contributed to the higher dispersion of iron species on the surface of the catalyst. Among various vanadium-modified iron catalysts supported on AC, 3% Fe–0.5% V achieved the best SCR activity and SO2 tolerance. In the presence of H2O, SO2 had a severe deactivation effect on both vanadium- and non-vanadium-modified catalysts, yet the inhibition effect of H2O and SO2 was reversible on 3% Fe–0.5% V at relatively low space velocity. It was found that the vanadium additive promoted the formation of sulfate species. The formed sulfate species increased the surface acidity and thus enhanced the tolerance toward SO2.
