Abstract

Procédé de dénitration de gaz d'échappement. Ce procédé consiste: - à insuffler un gaz oxydant dans le gaz d'échappement pour oxyder le monoxyde d'azote contenu dans ce gaz d'échappement en dioxyde d'azote ; - à irradier par la lumière ledit gaz d'échappement contenant ledit dioxyde d'azote et le gaz oxydant de manière à transformer ce dioxyde d'azote en acide nitrique; et - à éliminer cet acide nitrique absorbé dans une solution absorbante. Suppression ou diminution de la pollution par l'épuration des gaz d'échappement.
