摘要：
O-2 and SO2 transient response experiments were carried out to study the influence Of SO2 on NO removal over the V2O5/AC (activated coke) catalyst in the presence of H2O VOSO4 formed in the reaction of SO2 with V2O5 resulted in the decrease in NO removal activity of the V2O5/AC catalyst. The amount Of VOSO4 in the catalyst was affected by both SO2 concentration and the amount Of SO2 that was captured. Micropores of the V2O5/AC catalyst were favorable for the migration and deposition of SO3 and therefore benefited the NO removal over the catalyst.
