NOVELTY - The biomass coke fluidized bed reactor comprises a reactor shell for holding a reaction material, a reactor inner lower part provided with a distributor, and a reactor upper part for preventing the escape of catalyst. The reactor shell comprises a raw material inlet and a product exit. The raw material inlet comprises a biomass coke inlet. The biomass coke inlet is set on a side wall of the reactor shell and above the distributor. A distance between the biomass coke inlet and the distributor is 2-100 cm. The product exit includes a reactor gas exit and a liquid outlet.    USE - Biomass coke fluidized bed reactor.    ADVANTAGE - The fluidized bed reactor ensures the mixing of the biomass coke and the catalyst so as to rapidly promote coking phenomenon, thus preventing the polymerization reaction of the biomass coke.    DETAILED DESCRIPTION - The biomass coke fluidized bed reactor comprises a reactor shell for holding a reaction material, a reactor inner lower part provided with a distributor, and a reactor upper part for preventing the escape of catalyst. The reactor shell comprises a raw material inlet and a product exit. The raw material inlet comprises a biomass coke inlet. The biomass coke inlet is set on a side wall of the reactor shell and above the distributor. A distance between the biomass coke inlet and the distributor is 2-100 cm. The product exit includes a reactor gas exit and a liquid outlet. The reactor gas exit is arranged on a top part of the reactor shell. The liquid outlet is arranged on an upper end part of the side wall of the reactor shell. The raw material inlet further comprises a catalyst inlet set on the reactor top part, a hydrogen inlet set on the reactor shell and a circulation oil inlet arranged below the distributor. The reactor shell and a reactor shell body are connected a separate circulation system. The separate circulation system comprises a gas liquid separator and a circulation pump. The gas liquid separator is provided with a liquid inlet set on an upper end of the reactor side wall, and an oil inlet set in a lower part of the reactor side wall. A bottom part of the gas liquid separator is set with a liquid discharging port. A top part of the gas liquid separator is set with a gas exit. The oil port and the liquid inlet are connected to an inlet of the circulation pump. The liquid outlet is connected to an exit of the circulation pump and the circulation oil inlet. The separate circulation system is further provided with a liquid level controller. A holding liquid inlet is connected with the oil inlet of the gas liquid separator. The reactor shell is set with a catalyst outlet tube. An upper end of the catalyst outlet tube extends to an upper end of the distributor. A lower end of the catalyst outlet tube extends to the bottom of the reactor shell. The liquid outlet of the reactor shell is set with a filter or a cyclone separator. The biomass coke inlet is set on an oil tube.
