Definitions
- the invention particularly relates to a method of manufacturing a catalyst for integration in a catalytic converter system useful for the treatment of an engine exhaust gas of a vehicle. It is known to use catalysts based on a zeolite and palladium as active materials for the selective catalytic reduction of nitrogen oxides using methane as reducing agent in the presence of an excess of oxygen (see publication Y Nishizaka, M. Misono, Chem Lett, 8 (1993) 1295). Incorporation of cobalt in this type of catalyst has been described as improving the activity and stability of catalysts (see Ogura et al .: Ogura, Y. Sugiura, Hayashi, E. Kikuchi). Catal. Lett. 42 (1996) 185).
- the inventors have thus found that it was possible to make the catalyst less sensitive to the water vapor present in the exhaust gas by performing during the manufacture of this catalyst a steam treatment under particular conditions. Furthermore, the fact that the catalyst is based on cerium allows its integration into a vehicle unlike cobalt catalysts which are prohibited for this type of application. Another important difference between palladium / cerium catalysts and palladium / cobalt catalysts is that these systems have an "inverted" operation in that cobalt is the main catalyst in a palladium / cobalt system while palladium is the main catalyst. in a palladium / cerium system.
- the gas phase may comprise an inert gas and water vapor.
- the inert gas may for example be nitrogen, a rare gas such as argon or a mixture of these gases.
- the gaseous phase may further comprise oxygen, for example in a volume content of between 5% and 25%.
- the gaseous phase can in particular comprise nitrous oxide, oxygen and water vapor.
- the gaseous phase may comprise air and water vapor.
- the mass content of palladium in the treated structure may be greater than or equal to 0.1%, for example 0.3%, and may for example be between 0.1% and 1%.
- FIGS. 1A and 1B show that the treatment with water vapor according to the invention gives a significant improvement in the conversion rate of nitrogen oxides to dinitrogen and generally promotes the reduction of the oxidation of methane.
