Abstract
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 regenerator 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 distribution. 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 distribution without destruction of the catalyst.
