Summary:Increase propane dehydrogenation activity of a partially deactivated dehydrogenation catalyst by heating the partially deactivated catalyst to a temperature of at least 660°C, conditioning the heated catalyst in an oxygen-containing atmosphere and, optionally, stripping molecular oxygen from the conditioned catalyst. La présente invention concerne un procédé permettant d'augmenter l'activité de déshydrogénation du propane d'un catalyseur de déshydrogénation partiellement désactivé, le procédé comprenant le chauffage du catalyseur partiellement désactivé jusqu'à une température d'au moins 660 °C, le conditionnement du catalyseur chauffé sous une atmosphère contenant de l'oxygène et, éventuellement, l'extraction de l'oxygène moléculaire contenu dans le catalyseur conditionné.
