Title (EN) COMPOSITE CATALYST FOR THE LOW TEMPERATURE DECOMPOSITION OF NITROUS OXIDE, AND METHOD OF MANUFACTURE THEREOF
(FR) CATALYSEUR COMPOSITE CONÇU POUR LA DÉCOMPOSITION À BASSE TEMPÉRATURE D'OXYDE NITREUX, ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract: front page image
(EN)A composite catalyst according to the present invention contains cobalt oxide at 25 - 88.6 % by weight, zinc oxide at 10.99 - 60 % by weight as the substantive components, wherein the zinc oxide is introduced in two stages, during precipitation as well as prior to the forming of the catalyst. The ratio of zinc oxide introduced during the precipitation to the zinc oxide added prior to the forming of the catalyst is 1 :0.26-13.3and it also contains components which improve activity, in the form of alkali metals at 0.01 -5 % by weight calculated in terms of oxides of these metals, and graphite at 0.4-10 %. Preferably, the alkali metals present in the catalyst composition are sodium and/or potassium.
(FR)L'invention concerne un catalyseur composite qui contient 25 - 88,6% en poids en oxyde de cobalt, 10,99 - 60% en poids en oxyde de zinc comme composants importants ; l'oxyde de zinc est introduit en deux étapes, lors de la précipitation et avant la formation du catalyseur. Le rapport de l'oxyde de zinc introduit lors de la précipitation et de l'oxyde de zinc ajouté avant la formation du catalyseur est de 1 :00,26-13,3 , il contient également des composants qui améliorent l'activité, sous la forme de métaux alcalins à 0,01 - 5% en poids en termes d'oxydes de ces métaux, et du graphite à 0,4 - 10%. De préférence, les métaux alcalins présents dans la composition du catalyseur sont le sodium et/ou le potassium.
