The invention introduces a catalyst multi-section regeneration method and an apparatus, firstly, a spent catalyst enters a first section regenerator, and is in contact reaction with oxygen-containing gases in the first section regenerator, a second section regenerator and a third section regenerator sequentially, oxygen-containing regeneration flue gas of the first section enters the second section for continuous utilization, and the fresh compressed air is input to the third section for regeneration reaction, so as to complete the whole regenerative process. The fresh compressed air can alsobe supplemented to the first section regeneration reaction or the second section regeneration reaction, and the catalyst can also reflux to other sections for regeneration. The regeneration apparatusis composed of a first section turbulent bed regenerator, a second section turbulent bed regenerator and a third section turbulent bed regenerator in series connection, a distribution plate or a baffle and a catalyst standpipe are arranged, and all the regenerators are in coaxial arrangement. The invention adopts the multi-section counter-current regeneration, increases the average chemical kinetics speed, strengthens the regenerative process, saves the oxygen-containing gas usage, and reduces the production expense; and realizes the feeding of the spent catalyst from the bottom part or the middle part of each regenerator, lowers the height of the corresponding catalytic conversion device, shortens the oil-gas pipe-line, and reduces the construction investment.
