FIELD: technological processes.
SUBSTANCE: invention discloses hydrolytic lignin pellets made in the form of fuel pellets compressed from hydrolytic lignin, obtained by the method of hydrolysis of wood waste with sulfuric acid solutions, characterized by the fact that before processing the hydrolytic lignin is enriched with derived waste of hydrolysis production, and before pressing, it is finely cleaned, sorted into fractions, followed by the removal of mineral elements and decreasing ash content. Also a method for producing hydrolyzed lignin pellets is disclosed.
EFFECT: technical result consists in obtaining pellets that have optimal characteristics: they have a high calorific efficiency, high mechanical strength, and when they are burned, no ash residue is formed.
