Catalytic conversion catalyst regeneration method

The invention relates to a catalytic conversion catalyst regeneration method. The method includes that: a spent catalyst enters a regeneration zone of a regenerator, and contacts with main air to undergo a combustion reaction, the obtained regenerated catalyst goes into a buffer zone to be cooled and then returns to a reactor, and the flue gas is discharged from the top of a settlement zone. The invention adopts the buffer zone to engender uniform catalyst temperature distribution and can reach a cooling effect on a regenerator dilute phase, and the phenomenon of an overtemperature dilute phase is not easy to appear.
