| description | A spent catalyst distributor for distributing spent catalyst in a catalyst regenerator vessel housing a dense phase catalyst bed and a dilute phase catalyst bed. The spent catalyst distributor comprises a conduit comprising a proximal end and a distal end. The conduit projects horizontally or horizontally and downwardly into the regenerator vessel and includes an opening located at the distal end for introducing the spent catalyst at a first location inside the regenerator vessel. The conduit further includes a plurality of orifices located along a length of the conduit between the distal end and an inner wall of the regenerator vessel for introducing the spent catalyst at a plurality of locations inside the regenerator vessel. |
