Definitions
- the term “specific surface” is understood to mean the BET specific surface area determined by nitrogen adsorption in accordance with standard ASTM D 3663-78 established on the basis of the BRUNAUER - EMMETT-TELLER method described in the periodical "The Journal of the American Chemical Society, 60 , 309 (1938) ". This surface characteristic is obtained by the choice of a suitable support, in particular having a sufficiently high specific surface.
- the preparation of the stabilized alumina is carried out in a manner known per se, in particular by impregnating the alumina with solutions of salts, such as nitrates, of the abovementioned stabilizing elements or else by co-drying of an alumina precursor and salts of these elements then calcination.
- salts such as nitrates
- Curing can be done by alumina in water suspension and then heating at a temperature of for example between 70 C and 110 C. After curing, the alumina is subjected to a heat treatment.
- the stabilizer content expressed by weight of stabilizer oxide relative to the stabilized alumina is generally between 1.5 and 15%, more particularly between 2.5 and 11%.
- the support can also be based on silica. It can also be based on silica and titanium oxide in an atomic proportion Ti / Ti + Si of between 0.1 and 15%. This proportion can be more particularly between 0.1 and 10%.
- a support is described in particular in patent application WO 99/01216, the teaching of which is incorporated here.
- cerium oxide and zirconium oxide can be used, these oxides possibly being in the form of a mixed oxide or of a solid solution of zirconium oxide in l cerium oxide or vice versa.
- These supports can also be obtained by a second type of process which comprises a step in which a solution of a cerium salt, a solution of a zirconium salt and an additive chosen from anionic surfactants, non-surfactants, are reacted. ionic, polyethylene glycols, carboxylic acids and their salts, the reaction possibly being able to take place in the presence of a base and / or an oxidizing agent.
- the support is optionally dried and then it is calcined. It should be noted that it is possible to use a support which has not yet been calcined prior to impregnation.
- the deposition of the active phase can also be done by atomization of a suspension based on salts or compounds of the elements of the active phase and of the support. The atomized product thus obtained is then calcined.
- composition of the invention as described above is in the form of a powder but it can optionally be shaped to be in the form of granules, beads, cylinders or honeycombs of variable dimensions.
- the invention also relates to a gas treatment process with a view to reducing the emissions of nitrogen oxides using the composition of the invention.
- This example shows the resistance to aging of a composition according to the invention.
- the WH is of the order of 150,000 h "
- composition according to the invention has improved resistance to aging.
- composition according to the invention has improved resistance to SO 2 .
