Process for the removal of sulfur - and nitrogen oxides or only nitrogen oxides from waste gases

摘要

Carbonaceous materials are impregnated with bromine, chlorine, iodine or their compounds, 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 trapped by the carbonaceous materials and can be removed from the flue gas with a very high percent removal.
