Claim 9:
10. The method according to claim 9, wherein the method comprises: allowing the spent catalyst in the reaction zone to enter the fluidized bed regenerator through a first stripper and a spent catalyst delivery pipe, and to contact and react with a regeneration gas to obtain a first stream with a flue gas and the regenerated catalyst; allowing the first stream to enter a third gas-solid separation unit to separate the flue gas and the regenerated catalyst; and
allowing the separated regenerated catalyst to enter the coke control zone of the fluidized bed reactor through a second stripper, a regenerated catalyst delivery pipe, and a first gas-solid separation unit, and to contact and react with the coke control raw material.
