FIELD: chemistry.
SUBSTANCE: invention relates to the process of biomass processing. The method of processing raw material - lignocellulosic biomass, in which it is subjected to liquefaction by treatment with hot pressurized liquid water at subcritical conditions, wherein the temperature is from 330°C up to lower than 374°C and pH is less than 3.0. The invention is also directed to quenching of liquefaction process according to the above, to prevent, minimize or eliminate clogging and/or blocking of the process equipment with biomass adhesive components during processing according to the above, and to the use of additives in the biomass liquefaction.
EFFECT: invention provides processing by liquefying the biomass.
