Regenerated catalyst cooling method

Abstract

The present invention provides a method of cooling a regenerated catalyst and a device thereof, which employs low-line-speed operation, wherein a range of the superficial gas velocity is 0.005-0.7 m/s, wherein at least one fluidization wind distributor is provided, wherein the main fluidization wind enters the dense bed layer of the catalyst cooler from the distributor, and the heat removal load of the catalyst cooler and/or the temperature of the cold catalyst is controlled by adjusting the fluidization wind quantity. The method and a device thereof of the present invention has an extensive application range, and can be extensively used for various fluid catalytic cracking processes, including heavy oil catalytic cracking, wax oil catalytic cracking, light hydrocarbon catalytic conversion and the like, or used for other gas-solid fluidization reaction charring processes, including residual oil pretreating, methanol to olefin, methanol to aromatics, fluid coking, flexicoking and the like.
