ABSTRACT:
A regeneration process is described that eliminates or greatly reduces thermal channelling in a cooling zone bed. The method controls the flow rate of cooling gas independently of the requirements of the regeneration process for combusting coke and for halogenating or drying the catalyst. In one embodiment, a portion of a cooling stream is bypassed around a cooling zone and then passed to a drying zone. In another embodiment, one portion of a cooling stream from a cooling zone is vented, and another portion of the stream is passed to a drying zone.
