A method of ageing a catalyst material comprising at least the steps of. (a) heating a gaseous stream; (b) adding a least one pure hydrocarbon gas and an oxygen-containing gas to the heated gaseous stream to provide a combined stream; and (c) passing the combined stream through the catalyst material. The use of at least one pure hydrocarbon gas and an oxygen-containing gas allows the present invention to maximise re-circulation of the exit stream from the catalyst material for reuse, whist maintaining the correct C, H and O proportions being provided in the combined stream to replicate realistic use of the catalyst material.
La présente invention se rapporte à un procédé de vieillissement dun matériel catalytique comprenant au moins les étapes consistant à : (a) chauffer un flux gazeux ; (b) ajouter au moins un gaz dhydrocarbure pur et un gaz contenant de loxygène au flux gazeux chauffé afin de produire un flux combiné ; et (c) faire passer le flux combiné dans le matériel catalytique. Lutilisation dau moins un gaz dhydrocarbure pur et dun gaz contenant de loxygène permet à la présente invention de maximiser la remise en circulation du flux de sortie provenant du matériel catalytique en vue dune réutilisation, tout en maintenant les bonnes proportions de C, H et O proportions produites dans le flux combiné afin de reproduire lutilisation réaliste du matériel catalytique.
