ABSTRACT:
A catalyst regeneration process and apparatus for the oxidative removal of coke from a coke-contaminated fluid catalyst. The process utilizes a high temperature coke combustion zone and a catalyst disengagement zone. A mixture of coke-contaminated catalyst, and oxygen-containing gas are contacted in the combustion zone and from there, the regenerated catalyst and flue gas mixture passes to the catalyst disengagement zone. There are one or more diplegs through which regenerated catalyst flows from the disengagement zone to the combustion zone. The diplegs are sized so as to ensure a low maximum accumulation of catalyst in the disengagement zone. The temperature at a lower locus of the combustion zone may be controlled by control of the catalyst inventory in the reactor-regenerator system.
