Apparatus for controlling catalyst temperature during regeneration |
摘要 |
A catalyst cooler apparatus and process for use with a two-stage regeneration system in a fluidized catalytic cracking process having a device to remove hot catalyst from the second regeneration zone at a point above the air distribution ring under the surface of the catalyst bed equivalent to the catalyst exit to the reactor, a heat exchanger for indirect heat exchange and cooling of the catalyst and a return device for returning the cooled catalyst to the second regeneration zone at or near the bottom of the catalyst bed, beneath the air distribution ring.
