FIELD: biochemistry.
SUBSTANCE: group of inventions relates to biochemistry. Method for hydrolysis of lignocellulosic biomass and a hydrolyzate of the biomass obtained by the above said method (variants) is proposed. Method includes reducing the particle size of the original lignocellulosic biomass, preparing a mixture and maintaining it in contact with water at the temperature of from 374 °C up to 575 °C and at the pressure of from 22.1 MPa up to 80 MPa during from 0.1 to 10 seconds to obtain a saccharide containing 5 or 6 carbon atoms. Herewith the said mixture contains water, a lignocellulosic biomass with a particle size of less than 500 mcm and exogenous acid.
EFFECT: invention makes it possible to use a feedstock resistant to auto-hydrolysis, as well as to use a significant portion of self-energy during the method implementation.
