The present invention describes a device for controlling cooling of a heat transfer solid supplying or withdrawing heat to or from a unit carrying out globally endothermic or exothermic reactions respectively. The exchange bundle of said device is in a triangular pattern.

The present invention provides a method of cooling and cycling a regenerated catalyst. The regenerated catalyst that is from the regenerator is cooled by the catalyst cooler to 200-720 C., and without being mixed with the hot regenerated catalyst directly enters a riser reactor, or mixes with another part of hot regenerated catalyst that has not been cooled to obtain a mixed regenerated catalyst with a temperature below the regenerator temperature, and enters the riser reactor. The hydrocarbon raw material performs the contact reaction with the catalyst in the riser reactor, a reactant stream enters a settler to perform a separation of the catalyst and an oil gas, the separated spent catalyst is steam stripped by a steam stripping section and enters a regenerator to be charring regenerated, and the regenerated catalyst after being cooled returns to the riser reactor to be circularly used. The bottom of each of the catalyst coolers is provided with at least one fluidized medium distributor, the range of the superficial gas velocity is 0-0.7 m/s (preferably 0.005-0.3 m/s, and most preferably 0.01-0.15 m/s), and the temperature of the cold regenerated catalyst is controlled mainly by adjusting a flow rate of the fluidized medium. The method of cooling and cycling a regenerated catalyst of the present invention has extensive application, and can be used for various fluidized catalytic cracking processes, including heavy oil catalytic cracking, wax oil catalytic cracking, gasoline catalytic conversion reforming and the like, and can also be used for other gas-solid reaction processes, including residual oil pretreating, methanol to olefin, methanol to aromatics, methanol to propylene, fluid coking, flexicoking and the like.

A catalyst regeneration method is suitable for use in a fluidized catalytic cracking unit that includes a catalytic cracking reactor and a catalyst regenerator. The regeneration method includes the steps of: 1) providing a bio-based liquid phase fuel; 2) introducing the bio-based liquid phase fuel into a catalyst regenerator or a stripping section of the catalytic cracking reactor; 3) introducing an oxygen-containing gas into the catalyst regenerator; and 4) sending the spent catalyst from the catalytic cracking reactor to the catalyst regenerator, where the spent catalyst is contacted with the bio-based liquid phase fuel or the residue thereof and oxygen-containing gas to carry out coke burning regeneration. This method can greatly reduce the carbon emission of the catalytic cracking unit and can also provide energy for other process units and also converts part of the bio-based liquid phase fuel into chemicals.

A process for regenerating catalyst from a fluidized catalytic process is disclosed. The process comprises passing a CO.sub.2 oxidation stream to a regenerator in which coke is combusted from catalyst to provide a CO.sub.2 rich flue gas stream. The CO.sub.2 rich flue gas stream is separated into an underflow stream comprising catalyst fines and a CO.sub.2 rich flue gas overflow stream. The overflow stream is separated into a recycle stream and a power recovery stream. The recycle stream of the overflow stream is recycled to the regenerator.
