摘要： A method for processing soot containing one or more rare earths, wherein said soot is contacted with an oxygen-containing gas, is disclosed. The method comprises (a) preparing an aqueous phase comprising a dispersion of at least one oxygenated metal compound; (b) simultaneously or consecutively contacting a suspension from step (a) with an organic phase including at least one amphiphilic agent and preferably an organic mixture or compound as the solvent; and (c) recovering the organic phase. Said oxygenated metal compound is produced by means of a method according to which a solution including at least one soluble rare-earth salt, usually an acetate and/or a chloride, is prepared; the solution is contacted with a basic medium and the resulting reaction mixture is maintained at a basic pH; and the precipitate formed by atomisation or freeze-drying is recovered. Said method is useful in inorganic synthesis and catalysis.

摘要： The invention concerns a device for purifying an internal combustion engine exhaust gases comprising an internal combustion engine capable of consuming fuel with lean air-fuel mixture ratios, means for adsorbing NOx arranged in the engine exhaust line, said means being of the type which adsorb the NOx present in the exhaust gases in the presence of excess oxygen and which release the adsorbed NOx when the oxygen concentration of the exhaust gases decreases. The invention is characterised in that the NOx adsorbing means do not contain any composition capable of acting as NOx reducing catalyst and in particular no precious metal and a three-way catalyst is installed in the exhaust line downstream of the NOx adsorbing means.

摘要： A zirconium oxidebased composition containing cerium oxide and having a specific surface area of at least 30 m2/g after calcining for six hours at 900 °C. The composition is a pure solid solution of cerium oxide in zirconium oxide. In an alternative embodiment, the composition may further include a doping element and have a specific surface area of at least 25 m2/g after calcining for six hours at 1000 °C. A method for preparing such compositions is also disclosed, wherein a mixture containing a zirconium compound and a cerium IV compound is prepared in a liquid medium; the mixture is heated to over 100 °C; after heating, the resulting reaction medium is adjusted to a basic pH; the resulting precipitate is recovered; and said precipitate is calcined. If required, the doping element is added to the starting liquid mixture or to the reaction mixture obtained after the heating step.
