FIELD: chemistry.
SUBSTANCE: invention relates to production of liquefied fuel from biomass, which can be used as fuel for motorcars or motorcycles or as fuel for boilers and energy generators. The method of producing liquefied fuel, involving addition of a solvent containing an organic solvent and having moisture content brought to 10-25 wt %, including moisture contained in the biomass, to biomass containing lignocellulose, and liquefying the biomass at temperature from 250 to 350°C, in which the solvent is added in amount of 5-20 times more than the weight of dry substances in the biomass.
EFFECT: use of relatively cheap liquefying apparatus, maintaining a balance between liquefaction of water-insoluble lignin and liquefaction of water-soluble cellulose to achieve high output of liquefied fuel compared to content of dry substances in biomass, low amount of slag obtained from an alkaline catalyst.
