Title (EN) METHODS OF REACTIVATING AN AROMATIZATION CATALYST
(FR) PROCÉDÉS DE RÉACTIVATION D'UN CATALYSEUR D'AROMATISATION
Abstract:
(EN) A method of reactivating a spent catalyst comprising a metal and a catalyst support, the method comprising redispersing the metal in the spent catalyst to produce a redispersed spent catalyst, contacting the redispersed spent catalyst with a reactivating composition to produce a redispersed, reactivated spent catalyst, and thermally treating the redispersed, reactivated spent catalyst to produce a reactivated catalyst. A method comprising employing a fresh aromatization catalyst in one or more reaction zones for a time period sufficient to produce a spent catalyst, reducing the amount of carbonaceous material associated with the spent catalyst to produce a decoked spent catalyst, contacting the decoked spent catalyst with a redispersing composition to produce a decoked redispersed spent, contacting the decoked redispersed spent catalyst with a reactivating composition to produce a decoked redispersed reactivated spent catalyst, and thermally treating the decoked, reactivated spent catalyst to produce a reactivated catalyst.
(FR) L'invention concerne un procédé de réactivation d'un catalyseur usé comprenant un métal et un support de catalyseur, le procédé comprenant la redispersion du métal dans le catalyseur usé de manière à produire un catalyseur usé redispersé, le contact du catalyseur usé redispersé avec une composition de réactivation de manière produire un catalyseur usé, redispersé et réactivé, et le traitement thermique du catalyseur usé, redispersé et réactivé de manière à produire un catalyseur réactivé. L'invention concerne également un procédé comprenant l'utilisation d'un nouveau catalyseur d'aromatisation dans une ou plusieurs zones réactionnelles pendant une durée suffisante pour produire un catalyseur usé, la réduction de la quantité de matières carbonée associée au catalyseur usé pour produire un catalyseur usé décokéfié, le contact du catalyseur usé décokéfié avec une composition de redispersion pour produire un catalyseur usé décokéfié et redispersé, le contact du catalyseur usé décokéfié et redispersé avec une composition de réactivation pour produire un catalyseur usé, décokéfié, redispersé et réactivé, et le traitement thermique du catalyseur usé décokéfié et réactivé pour produire un catalyseur réactivé.
