Title
(EN) IMPROVED ROBUSTNESS OF COKE BURNING FROM CATALYST FOR LIGHT PARAFFIN DEHYDROGENATION PROCESS
(FR) ROBUSTESSE AMÉLIORÉE DE LA COMBUSTION DE COKE À PARTIR D'UN CATALYSEUR POUR PROCÉDÉ DE DÉSHYDROGÉNATION DE PARAFFINES LÉGÈRES
Abstract
(EN)
A process for a continuous regeneration of a catalyst wherein the regeneration section includes at least two separate zones. The regeneration includes an upper combustion zone, and an lower combustion zone, where the process utilizes at least two independent regeneration gas loops for control of the amount of oxygen to regenerate the catalyst. The upper combustion zone can be divided into multiple zones, and the combustion zone can be divided into multiple zones.
(FR)
L'invention porte sur un procédé pour une régénération en continu d'un catalyseur, la section de régénération comprenant au moins deux zones séparées. La régénération comprend une zone de combustion supérieure et une zone de combustion inférieure, le procédé utilisant au moins deux boucles de gaz de régénération indépendantes pour le réglage de la quantité d'oxygène pour régénérer le catalyseur. La zone de combustion supérieure peut être divisée en de multiples zones et la zone de combustion peut être divisée en de multiples zones.
