ABSTRACT:
A catalyst regeneration process and apparatus for the oxidation of coke from a spent catalyst and for the conversion of CO resulting from the oxidation of coke to CO.sub.2.
Novel feature of the process is the mixing of a portion of regenerated catalyst produced in a coke oxidation zone and heated to a higher temperature in a CO-conversion zone with spent catalyst and passing the mixture to a coke-oxidation zone to increase the temperature within the coke oxidation zone and to disperse spent catalyst more evenly across that zone thereby increasing the rate, extent and evenness of coke oxidation. The regeneration apparatus includes components by which this can be accomplished.
