FIELD: biotechnology.SUBSTANCE: method of processing plant biomass comprises its hydrothermomechanical treatment in a liquid medium at a temperature of self-heating, and separating the resulting suspension to separate fractions. At that the plant biomass with the ratio water/biomass of 10:90 to 90:10 is subjected to hydrothermomechanical treatment at a temperature of self-heating of the reaction mixture of 45°C - 240°C to obtain a particle size of solid phase of not more than 1000 mcm, the resulting aqueous suspension is separated at a temperature of the reaction mixture to the solid cellulose-containing fraction and a liquid fraction containing lignin, which is mixed with the plant biomass, not subjected to hydrothermomechanical treatment and/or with plant biomass previously subjected to the aid hydrothermomechanical treatment, liquid is removed from the resulting mixture, and the resulting mass is directed to form the target products.EFFECT: method enables to improve environmental friendliness and versatility of the process of processing plant biomass, to eliminate from the technological cycle the toxic organic solvents, and to obtain environmentally friendly products from natural plant materials.3 cl, 3 tbl, 3 ex |
