ABSTRACT:
A catalyst comprising carbonaceous materials such as activated carbon, etc. impregnated with bromine, iodine, chlorine or their compounds, is impregnated with a promoter containing a specific metal, and brought in contact with a flue gas in the presence of ammonia, whereby nitrogen oxides and sulfur oxides contained in the flue gas are removed with a very high percent removal. The removal can be carried out at a temperature much lower than that of the conventional process.
