    Abstract: A platinum group component catalyst, used in a hydroconversion unit comprising a plurality of reactors in series, is regenerated to remove carbonaceous matter from the catalyst without contaminating the catalyst with sulfur compounds by purging the hydroconversion unit of hydrocarbons, circulating an inert gas through the hydroconversion unit at a pressure of from 50 to 1000 p.s.i.g., controlling the inlet temperature in all but the terminal reactor to below about 500* F. while controlling the inlet temperature in the terminal reactor at from 500* to 700* F., then introducing an oxygen-containing gas into the terminal reactor to remove carbonaceous matter from the catalyst but insuring that the oxygen is discontinued when the exit stream from the terminal reactor contains more than about 0.1 volume percent oxygen.

    Abstract: A process in which spent catalyst is regenerated with or without the complete combustion of CO in a regeneration zone comprising a first dense bed, a dilute phase transport riser and a second dense bed. Higher velocities and higher O2 concentrations employed within the regeneration zone result in shorter catalyst and gas residence time, reduced catalyst inventory, lower catalyst makeup rate, improved regeneration, and improved catalyst stability. The substantially complete combustion of CO eliminates CO pollution of the atmosphere without the need for a CO boiler and decreases feed preheat requirements.
