Abstract:

The MnOx/AC catalyst was prepared by the equal volume impregnation method.The effects of manganese precursor,catalyst calcination temperature and loading on denitrification activity were investigated.The catalyst was characterized by H2-TPR.The results show that the catalyst with KMnO4 as the precursor of manganese,with the loading Mn by 20%(wt.%) and calcination at 400  ℃ has the best adsorption and denitrification performance.At 180  ℃,the maximum denitrification rate is above 99%,and still above 80% after 120 minutes of reaction.
