AIR DISTRIBUTION APPARATUS (D#74,459-F) Abstract of the Disclosure An air distribution apparatus for delivering an oxygen-carrying gas such as air to a zone of spent catalyst in a regenerator for the purpose of combusting air with the spent catalyst in order to rejuvenate the catalyst. A header support assembly is adapted for mounting in a re- generator which receives the spent catalyst. A hollow header ring is mounted onto the header support assembly and includes a plurality of openings each having a nozzle mounted therein. Air is supplied to the header support assembly and thus to the hollow header ring at a pressure sufficiently high to effect a maximum desired pressure differential between header pressure and pressure in the zone of spent catalyst to cause maximum uniform air distri- bution. The nozzles mounted in the openings in the header ring decrease air velocity between nozzle inlet and nozzle outlet in order to provide for maximum uniform air distri- bution without destruction of the catalyst. -I-
