Title (EN) CATALYST REGENERATION METHOD
(FR) PROCÉDÉ DE RÉGÉNÉRATION DE CATALYSEUR
Abstract:
(EN) A process is disclosed for regenerating a used catalyst comprising two or more noble metals supported on a carrier. The method comprises calcining a used catalyst comprising a noble metal and a transition metal supported on an inorganic carrier in an oxygen-containing gas to produce a calcined catalyst; and contacting the calcined catalyst with a hydrogen-containing gas at a temperature higher than 430°C.
(FR) La présente invention concerne un procédé de régénération d'un catalyseur usé qui comprend deux métaux nobles ou plus supportés sur un vecteur. Le procédé comprend la calcination d'un catalyseur utilisé qui comprend un métal noble et un métal de transition supporté sur un vecteur inorganique dans un gaz contenant de l'oxygène pour produire un catalyseur calciné; et la mise en contact du catalyseur calciné avec un gaz contenant de l'hydrogène à une température supérieure à 430°C.
