Abstract

L’invention concerne un fluide pour la dépollution de moteurs thermiques, permettant d’effectuer de manière optimisée à la fois la réduction catalytique sélective des oxydes d’azote contenus dans les gaz d’échappement, ainsi que l’aide à la régénération du filtre à particules par combustion catalytique des particules de suies déposées dans le filtre à particules, ledit fluide étant constitué d’une solution homogène d’au moins un complexe organométallique de cuivre comprenant au moins un complexant et du cuivre de valence II, dans une solution aqueuse d’au moins un composé réducteur ou précurseur d’agent réducteur choisi parmi l’urée, le formamide, les sels d’ammonium, les sels de guanidine, seuls ou en mélange, dans lequel au moins un complexant est un acide polyaminocarboxylique, le ou lesdits complexant(s) étant optionnellement en excès molaire par rapport au cuivre. L’invention concerne également le procédé de préparation dudit fluide et son utilisation pour la dépollution de moteurs thermiques. Figure pour l’abrégé : Fig 1The invention relates to a fluid for depolluting internal combustion engines, making it possible to carry out in an optimized manner both the selective catalytic reduction of the nitrogen oxides contained in the exhaust gases, as well as aiding the regeneration of the filter particles by catalytic combustion of soot particles deposited in the particulate filter, said fluid consisting of a homogeneous solution of at least one organometallic copper complex comprising at least one complexing agent and valence copper II, in an aqueous solution at least one reducing compound or precursor of a reducing agent chosen from urea, formamide, ammonium salts, guanidine salts, alone or as a mixture, in which at least one complexing agent is a polyaminocarboxylic acid, or the said complexing agent(s) being optionally in molar excess with respect to the copper. The invention also relates to the process for preparing said fluid and its use for depolluting heat engines. Figure for abstract: Fig 1
