Abstract

Le catalyseur de conversion d'hydrocarbures formé de particules comprenant un métal du groupe VIII, un halogène en combinaison, un support formé d'un oxyde minéral réfractaire, et ayant été désactivé par dépôt de matière carbonée et perte d'halogène, est régénéré par gravité en envoyant les particules dans une première section alimentée en courant d'air et mélange vapeur d'eau halogène ou composé halogéné Après élimination de la majeure partie de la matière carbonée et augmentation de la teneur en halogène, les particules sont envoyées dans une deuxième section alimentée en courant d'air et mélange vapeur d'eau halogène ou composé halogéné Après élimination de la quasi-totalité de la matiere carbonée restante et augmentation e la teneur en halogène, les particules sont envoyées dans une section de séchage alimentée en air sensiblement sec pour y éliminer pratiquement toute l'eau contenue.
