METHOD OF PREPARING GRANULAR HYDROLYTIC LIGNIN

摘要

FIELD: preparation of producer gas and activated carbon. SUBSTANCE: claimed method comprises preparing hydrolytic lignin in granular form which is useful as fuel and original material for preparing producer gas and activated carbon. Initial hydrolytic lignin is triturated, granulated, and granular lignin is dried. Trituration is accompanied with adjustment of pH of initial hydrolytic lignin to 7.1-9.5. EFFECT: more efficient preparation method. 7 ex
