Abstract
A process for regenerating a catalyst used in a reaction zone. In a regeneration zone, the catalyst may be cooled before passing into a chloride rich zone. The regeneration zone may also receive a heated ambient oxygen in a catalyst heating zone. The regeneration zone may also receive recovered chloride from a chloride recovering zone which removes and recovers chloride from regeneration gas taken from the regeneration zone. Heated ambient oxygen may also be introduced into a chlorination zone.
