摘要
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.
