In this study, the deactivation of commercial V2O5-WO3/TiO2 selective catalytic reduction catalysts by Pb was discussed primarily, and the combined promotive effects of SO2 and HCl on Pb-poisoned V2O5-WO3/TiO2 catalysts were studied. The results show that the treatment with SO2 and HCl markedly improves the NOx conversion of Pb-poisoned catalysts. SO2 and HCl react with Pb chemisorbed on V2O5, which increases effectively the ratio of V5+ and active oxygen species and the amount of acid sites.
