Abstract

The invention relates to a Fischer-Tropsch synthesis fluidized bed reactor, wherein the fluidized bed reactor comprises a reactor cylinder and an internal component arranged in the reactor cylinder, and the internal component comprises a gas distribution mechanism, a heat exchange mechanism, a solid catalyst separation and circulation mechanism and a catalyst online feeding and discharging mechanism; the gas distribution mechanism comprises a first-stage gas distributor, a second-stage gas distributor and a third-stage gas distributor which is arranged in a main reaction dense-phase region ofthe fluidized bed reactor; the first-stage gas distributor and the second-stage gas distributor are arranged at the bottom of the reactor cylinder; a gas nozzle of the third-stage gas distributor transversely sprays gas to transversely cut longitudinally rising gas flow. Compared with the prior art, the reactor is reasonable in design structure and layout; the fluidized bed reactor is good in gas-solid contact in the reactor, uniform in fluid distribution, high in system heat transfer efficiency, uniform in temperature distribution, good in gas-solid separation effect, high in system operationflexibility and particularly suitable for design and operation of the large-scale Fischer-Tropsch synthesis fluidized bed reactor, and cavities in the fluidized bed reactor are avoided.
