Abstract: A catalyst regeneration apparatus for the oxidation of coke from a spent catalyst, said coke being converted to CO, and for the conversion of the CO to CO.sub.2. Hot regenerated catalyst is recycled from a dense bed in the regeneration zone to mix with incoming spent catalyst in a mixer zone. The mixer zone operates in dense phase and is supplied with a relatively small amount of a fluidizing medium, preferably air. After the mixing of spent and fresh catalyst is substantially completed, a relatively large amount of a regenerating gas, preferably air, is admixed with the catalyst mixture, and some coke oxidation occurs. The balance of coke oxidation takes place in a downstream-situated regeneration zone of substantially conventional design. There is a transfer section connecting the mixer zone to the regeneration zone through when the relatively large amount of the regenerating gas is admitted. The transfer section is preferably a substantially horizontal surface having an outside perimeter intermediate the outside perimeters of the regeneration and mixer zones. Regeneration gas addition is made through multiple perforations in the transfer section.

The hydrocarbon effluent stream is charged to an isostripper column. An isobutane vapor stream from the column is condensed in indirect heat exchange with the lower liquid stream from said column comprising n-butane. The lower liquid stream is flashed in indirect heat exchange with said vapor stream at conditions to provide a vapor phase, said vapor phase being compressed and recycled to said column at a temperature to promote vapor formation therein.

Abstract: A radial flow reactor design which allows the maintenance of a temperature profile along the height of a catalyst bed which descends through the reactor by gravity flow. Two feed inlet conduits are provided on the inlet side of the annular catalyst bed, with the inlets being divided by a porous flow control and distribution means. The inlet streams have different temperatures and the distribution means produces a changing admixture rate between the two streams along the bed. A preferred form of the distribution means is an open-topped cone located within the centerpipe of the reactor.

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.

Abstract: Methods of control and control systems for a catalyst regeneration process and apparatus for the oxidative removal of coke from a coke-contaminated fluid catalyst. Simultaneous production of hot regenerated catalyst and a relatively-cooler flue gas is provided. The process comprises a high temperature coke combustion zone, and a lower temperature heat removal zone. Coke contaminated catalyst, oxygen containing gas and regenerated catalyst from the heat removal zone are contacted in the high temperature combustion zone, the temperature of which is controlled by adjusting the rate at which catalyst is recycled from the heat removal zone. Catalyst maybe withdrawn from the top of the combustion zone and sent to the reaction zone at the controlled combustion zone temperature, the remainder of the catalyst and the hot flue gas pass to the upper heat removal zone, where both gas and catalyst are cooled, preferably by utilizing the catalyst as a heat transfer medium in a dense-phase heat exchange system. The optimum temperature may be achieved by mixing regenerated catalyst from the two zones, and 0-100% of regenerated catalyst may be withdrawn from either of the two zones. The extent of heat removal in the upper zone can be adjusted by changing the level of the dense bed in the heat removal zone, and this would be used for making gross changes in the quantity of the heat removed from the process.
