Abstract

L'invention concerne un procédé de transformation catalytique de composés organiques de l'azote. On fait réagir ces composés, isolément ou en mélange, avec O2 moléculaire, de façon à transformer C à liaison organique en CO2 et à transformer N à liaison organique en N 2 élémentaire et/ou hémioxyde N2 O. Application : purification des gaz industriels d'échappement, pour répondre aux règlements antipollution de l'air.
