Title (EN) SCR CATALYST FOR REMOVAL OF NITROGEN OXIDES
(FR) CATALYSEUR A REDUCTION CATALYTIQUE SELECTIVE POUR L'ELIMINATION D'OXYDES D'AZOTE
Abstract:
(EN) The present invention provides for catalysts for selective catalytic reduction of nitrogen oxides. The catalysts comprise metal oxides supporters, vanadium an active material and antimony a promoter that acts as a catalyst for reduction of nitrogen oxides, and at the same time, can promote higher sulfur poisoning resistance and low temperature catalytic activity. The amount of antimony of the catalysts is preferably 0.5 - 7 wt %.
(FR) La présente invention concerne des catalyseurs de réduction catalytiques sélective d'oxydes d'azote. Les catalyseurs contiennent des supports d'oxyde métallique, du vanadium ainsi qu'un matériau actif et de l'antimoine, un promoteur faisant office de catalyseur pour la réduction des oxydes d'azote et, en même temps, ils peuvent favoriser une plus grande résistance à l'empoisonnement par le soufre et une activité catalytique à basse température. La quantité d'antimoine des catalyseurs est comprise de préférence entre 0,5 et 7 % en poids.
