IMPROVED PROCESS OF LIGNOCELLULOSE BIOMASS FRACTIONING Russian patent published in 2015 - IPC C08B1/00 A23K1/12 C12P5/02 

FIELD: chemistry.

SUBSTANCE: invention relates to improved process of lignocelluloses biomass fractioning for further application in synthesis of chemical production or obtaining fuel or fuel additives based on vegetable raw material. Claimed is method of fractioning lignocelluloses biomasses into fractions of cellulose, hemicelluloses and lignin, where biomass is processed with vapours of concentrated organic acid at higher temperatures and in location(s) or close to location(s) of harvesting and accumulation of biomass to carry out, at least, partial depolymerisation or considerable solubilisation of hemicelluloses and lignins in biomass. Acid-processed biomass is dried and granulated for long-term bulk storage and/or transportation to the second installation, located at a distance. Acid-processed biomass can be recycled into target chemical production, fuels and/or fuel additives on local processing site or on the second installation, remote from local processing site, or granulated material can be used as forage for cattle in the place of production or on site for cattle feeding, remote from local processing site.

EFFECT: elaboration of improved method of lignocelluloses mass fractioning.
