METHOD AND APPARATUS FOR PRODUCING LIQUID BIOFUEL FROM SOLID BIOMASS

摘要

The invention relates to producing liquid hydro carbonaceous product (1) from solid biomass (2). In the invention solid biomass (2) is gasified in a gasifier (6) to produce raw synthesis gas (3). The raw synthesis gas (3) is conditioned to purify the raw synthesis gas (3) to obtain purified synthesis gas (4), the conditioning comprising lowering the temperature of the raw synthesis gas (3) in a cooler (19) producing saturated steam (51). Then the purified gas (4) is subjected to a Fischer-Tropsch synthesis in a Fischer-Tropsch reactor (5) to produce liquid hydro carbonaceous product (1). In the invention the saturated steam (51) produced by the cooler (19) is further superheated in a superheating boiler (50) for producing superheated steam (52).
