METHOD OF RAPID ACIDIC HYDROLYSIS OF LIGNOCELLULOSE MATERIAL AND HYDROLYTIC REACTOR Russian patent published in 2002 - IPC

FIELD: chemical technology. SUBSTANCE: invention relates to a method of acidic hydrolysis of lignocellulose material, for example, wood, straw, vegetables and so on used for production of sugars and lignin and also to a hydrolytic reactor unit for realization of the method to be proposed. The continuous acidic hydrolysis is carried out by the simultaneous delignification and saccharification in a single reaction cycle using an organic solvent dissolving lignin and a strong inorganic acid to provide the isolation of highly concentrated sugar solution. By combining the stages of saccharification and deliginification the invention provides the increase of sugar yield and the use of diluting acid. EFFECT: improved method of hydrolysis, decreased time of process and consumption for equipment. 18 cl, 3 dwg, 2 ex
