1. A fluidized bed reactor, wherein the fluidized bed reactor comprises a main shell and a coke control zone shell;
the main shell comprises an upper shell and a lower shell;
the upper shell encloses a first gas-solid separation zone, and the lower shell encloses a reaction zone;
the reaction zone axially communicates with the first gas-solid separation zone;
the coke control zone shell is circumferentially arranged on an outer wall of the main shell;
the coke control zone shell and the main shell enclose an annular cavity, and the annular cavity is a coke control zone;
n baffles are radially arranged in the coke control zone, and the n baffles divide the coke control zone into n coke control zone subzones, where n is an integer;
each of the n coke control zone subzones is provided with a coke control raw material inlet; and
a catalyst circulation hole is formed in each of n−1 of the n baffles, such that a catalyst and a coke control raw material entering the coke control zone flow in an annular direction.
