Zusammenfassung:	A spent catalyst distributor for distributing spent catalyst in a catalyst regenerator vessel (102, 202, 302, 402) housing a dense phase catalyst bed (108a) and a dilute phase catalyst bed (108b) is disclosed. The spent catalyst distributor comprises a conduit (110, 206, 306, 406) comprising a proximal end (112a, 208a, 308a, 408a) and a distal end (112b, 208b, 308b, 408b). The conduit (110, 206, 306, 406) projects horizontally or horizontally and downwardly into the regenerator vessel (102, 202, 302, 402) and includes an opening (114, 210, 310, 410) located at the distal end (112b, 208b, 308b, 408b). The conduit (110, 206, 306, 406) further includes a plurality of orifices (116, 212, 312, 412) located along a length of the conduit (110, 206, 306, 406) between the distal end (112b, 208b, 308b, 408b) and an inner wall (106a, 214, 314, 414) of the regenerator vessel (102, 202, 302, 402).
