Title (EN) PEROVSKITE-TYPE CATALYST AND PROCESSES FOR USING IT
(FR) CATALYSEUR DE TYPE PEROVSKITE ET SES MODES D'UTILISATION
Abstract: front page image
(EN)A mixed metal oxide having a perovskite-type structure ABO¿3-y¿, where A corresponds to a relatively large cation and B corresponds to a relatively small cation has an oxygen deficiency y of at least 0.1 and has at least two transition metals in the B position, one of which is Cu. The oxide is useful in the conversion of NO to N¿2? in mixtures containing CO and NO.
(FR)L'invention concerne un oxyde de métal mélangé présentant une structure ABO¿3-y¿ du type perovskite, dans laquelle A correspond à un cation relativement grand et B correspond à un cation relativement petit, ayant un manque d'oxygène y d'au moins 0,1 , et ayant au moins deux métaux de transition dans la position B, l'un étant Cu. L'oxyde est utile dans la transformation de NO en N¿2? dans des mélanges contenant CO et NO.
