FIELD: chemistry.
SUBSTANCE: invention relates to production of a liquid hydrocarbon product (1) from a solid biomass (2). According to the invention, the method of producing a liquid hydrocarbon product (1) from a solid biomass (2) involves: gasifying solid biomass (2) in a gasifier (6) to produce raw synthesis gas (3); preparing the raw synthesis gas (3) to purify the raw synthesis gas (3) to obtain purified synthesis gas (4), the preparation involving lowering the temperature of the raw synthesis gas (3) in a cooler (19) to obtain saturated steam (51); subjecting the purified gas (4) to a Fischer-Tropsch synthesis in a Fischer-Tropsch reactor (5) to obtain a liquid hydrocarbon product (1); treatment of the product (32) to separate the liquid hydrocarbon product (1), obtained from Fischer-Tropsch synthesis, also involves superheating the saturated steam (51) produced by the cooler (19) in a superheating boiler (50) for producing superheated steam (52, 53) by feeding saturated steam (51) into the superheating boiler (50) before using said saturated steam (51); the superheating boiler (50) operates almost exclusively with one or more by-products (9, 49, 48, 47) obtained in the method of producing a liquid hydrocarbon product (1) from solid biomass (2). Disclosed also is an apparatus for producing a liquid hydrocarbon product from biomass.
EFFECT: high energy efficiency of the method and apparatus for producing a liquid hydrocarbon product from biomass.
