FIELD: woodworking industry. SUBSTANCE: invention, in particular, relates to method including carbon black production stage. Broken down wood is preliminarily freed of soluble substances by extracting it with immiscible solvents including hexane and aqueous ethanol at 30-40 C. Extraction mixture is separated into liquid phase and solid sludge. Liquid phase is subjected to extraction with immiscible solvents including saturated aqueous solution of water-soluble salt, diethyl ether, and hexane at 5-20 C followed by isolation of natural resinous substances as final products from hexane solution utilizing vacuum distillation of hexane. From alcohol-ether solution, flavonoids are isolated by cryogenic drying at 30-40 C followed by afterpurification by preparative chromatography to give final flavonoid products: dihydroquercetin and dihydrokaempferol. Saturated aqueous solution is subjected to fractional crystallization to remove water- soluble salt and remaining aqueous solution of polysaccharides is subjected to drying at 80-100 C. Polysaccharides are then processed together with solid sludge in presence of hydrofluoric acid in liquid carbon dioxide at 25-30 C and pressure 16-37 MPa to give hydrolyzed products. Soluble products are converted by inversion at 130-140 C into monosaccharides that are further isolated. Solid hydrolysis products containing fluorinated lignin are carbonized to yield carbon black, resinous substances, and aqueous-organic condensate. Installation for implementation of invention is described. Method and installation increase efficiency of wood processing to 85.2%. EFFECT: enhanced process efficiency, reduced metal usage and power consumption. 11 cl, 1 dwg, 3 tbl
