Abstract

L'invention concerne un matériau de réduction catalytique sélective comprenant une particule sphérique comprenant une agglomération de cristaux d'un tamis moléculaire. Le catalyseur est un matériau cristallin qui est efficace pour catalyser la réduction catalytique sélective d'oxydes d'azote en présence d'un réducteur à des températures comprises entre 200 °C et 600 °C. L'invention concerne également un procédé pour réduire sélectivement des oxydes d'azote et un système de traitement de gaz d'échappement.
