Abstract[English]
The present invention relates to a catalyst for the catalytic reduction of nitrogen oxides in the presence of hydrogen (H2-SCR) comprising an active phase comprising platinum, tungsten and sodium, and a support comprising at least titanium dioxide, characterised in that: - the platinum content is between 0.01 and 10% by weight of platinum relative to the total weight of the catalyst; - the tungsten content is between 1 and 30% by weight of tungsten relative to the total weight of the catalyst; - the sodium content is between 0.5 and 5% by weight of sodium relative to the total weight of the catalyst.[French]
La présente invention concerne un catalyseur pour la réduction catalytique d'oxydes d'azote en présence d'hydrogène (H2-SCR) comprenant une phase active comprenant du platine, du tungstène et du sodium, et un support comprenant au moins du dioxyde de titane, caractérisé en ce que : - la teneur en platine est comprise entre 0,01 et 10% en poids en élément platine par rapport au poids total du catalyseur; - la teneur en tungstène est comprise entre 1 et 30% en poids en élément tungstène par rapport au poids total du catalyseur; - la teneur en sodium est comprise entre 0,5 et 5% en poids en élément sodium par rapport au poids total du catalyseur.
