Abstract (en)
[origin: WO2007131902A2] This invention concerns an alumina-based composition particularly for permitting the tapping of nitrogen oxides that are contained in a gaseous fluid. This composition is formed by alumina, cerium and a divalent metal M chosen from the group which includes barium, strontium or an association of these two elements and it is characterized in that at least 10% of the weight of element M expressed by weight of oxide in contrast to the total weight of the composition and also in that the aluminate compound of the metal element M, formula MAI204, is absent. In other words this compound is not detectable by x-ray diffraction of the composition, following its calcinations with the air at 700ºC for two hours.
