Abstract:The catalysts SO42  Mn–Co–Ce/TiO2/SiO2 were investigated for the low-temperature SCR of NO with NH3 in the presence of SO2. An excellent SO2 durability at low temperature was obtained with the catalyst used TiO2/SiO2 as support and modified with SO42 . The catalyst sulfated with 0.1 mol/L H2SO4 solution and then calcined at 300 °C exhibited the best NOx conversion efficiency of 99.5% at 250 °C in the presence of 50 ppm SO2. The conversion efficiency did not decrease after repeatedly used for 8 times.
