Abstract
An improved air distribution apparatus for a regenerator in a fluid catalytic cracking process has been invented. The improvement is in the nozzles which eject air from an air ring to a bed of coke deactivated catalyst. The nozzles are positioned to take air from the centerline of the air ring and are of length 4 to 8 diameters. The nozzles are noted for reduced aspirated catalyst erosion.
