F. which method comprises contacting the feedstock in a reaction zone with a mixture of regenerated fluidizable cracking catalyst and fluidizable low coke make solid particles comprising a refractory inorganic oxide in a ratio of low coke make solid particles to cracking catalyst from about 1:100 to about 10:1, the low coke made solid particles having a surface area of less than about 5 m.sup.2 /g and a coke making capability of less than about 0.2 weight percent coke on the spent low coke make solid particles in the ASTM standard method for testing cracking catalyst by microactivity test (MAT); separating the resulting vaporized hydrocarbon products from the mixture of deactivated fluidizable cracking catalyst and fluidizable low coke made solid particles; recovering the resulting vaporized hydrocarbon products; passing the mixture of cracking catalyst and low coke made solid particles to the regeneration zone for regeneration by removal of coke; and passing the resulting regenerated mixture of cracking catalyst and low coke make solid particles from the regeneration zone to the reaction zone to contact the feedstock as described above whereby the regeneration zone temperature is maintained at a reduced temperature as compared to an equivalent operation without the use of the fluidizable low coke make solid particles while simultaneously not affecting the operation of the reaction zone.

摘要： 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 which the relatively large amount of the regenerating gas is admitted. The transfer section is preferably a frustoconical surface, the horizontal cross section of smallest perimeter of which adjoins the outlet of said mixer zone, and regenerating gas addition is made at the base of the transfer section in order to provide a venturi effect which ensures good air-catalyst mixing.

摘要： A catalyst regeneration process and apparatus for the oxidative removal of coke from a coke contaminated fluid catalyst. The process comprises a high temperature coke combustion zone, a catalyst disengagement zone and an external heat removal zone comprising a shell and tube heat exchanger. Catalyst is cooled by passing it through the shell side of the heat exchanger with a cooling medium through the tube side. A mixture of coke contaminated catalyst, oxygen containing gas, and cool 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 passed through the heat exchanger. This rate is adjusted by adjusting the difference in catalyst head between the catalyst inlet and outlet of the heat exchanger and thus the hydraulic driving force which effects catalyst circulation through the heat exchanger.
