FIELD: chemistry.
SUBSTANCE: invention can be used for biomass gasification. Method of gasifying biomass in a fluidized bed includes drying the biomass and its feeding into the gasifier in a fluidized bed. Crude gas from the gasifier is fed into the recirculation cyclone, and after the cooler of the crude gas. Dust is collected in the hot gas filter connected after cooling the raw gas is returned to the feed system biomass. For the separation of harmful gases fed sorbent. Sorbent filter hot gas together with the dust separated from the crude gas is fed to the circulation until saturation.
EFFECT: invention improves the conversion of the carbon in the biomass gasification and maximize the use of the carrying capacity of the sorbent.
