Abstract
L'invention concerne un procédé et un dispositif pour le traitement catalytique d'effluents gazeux contenant des oxydes de soufre et d'azote et également de la poussière et de l'oxygène résultant de processus chimiques ou de la combustion de combustibles fossiles par exemple de combustibles de centrales ou secondaires, tels que des ordures ou des boues résiduaires, ou bien provenant d'usines de production de verre ou de ciment. Selon ledit procédé, les effluents gazeux sont libérés de leurs oxydes de soufre et d'azote en présence et/ou avec addition d'au moins une substance sélectionnée parmi les oxydes libres, les carbonates et les hydroxydes de calcium, magnésium, sodium et potassium, dans un réacteur comportant un catalyseur solide, à une température comprise dans la plage 200 DEG C - 500 DEG C.
