ABSTRACT:
The present invention provides for a process and associated apparatus for limiting the vertical mixing of catalyst in a fluidized catalyst regenerator so that spent catalyst entering the regenerator will remain at the top of the fluidized bed for a longer period of time. This is accomplished by employing a generally horizontally placed baffle device located between 2 ft.-4 ft. below the catalyst bed level in the regenerator.
