Disclosed is an improved regeneration process and system for the regeneration of a spent FCC catalyst in a regenerator without vertical partitions by introducing different fluidization gas streams to different regions of a dense phase catalyst zone at the lower end of the regenerator such as a high velocity central region and a low velocity annular zone are formed, positioned below a common dilute catalyst phase.
L~invention concerne un procédé amélioré de régénération et un système de régénération d~un catalyseur FCC usagé dans un régénérateur sans partitions verticales par introduction de différents courants gazeux de fluidisation dans différentes régions d~une zone du catalyseur de phase dense à l~extrémité basse du régénérateur, de manière à ce qu~une région centrale de vitesse élevée et une zone annulaire de vitesse faible se forment, positionnées sous une phase de catalyseur dilué commune.
