Bagasse extracts fractionation by combination of membrane and chromatographic technologies

P.-Y. Pontalier*, V. Oriez, J. Peydecastaing, ENSIACET, France

The lignocellulosic biomass valorization, for biofuel production, is industrially performed under acidic conditions, mainly at high acid concentration. The aim of this treatment is the production of monomeric sugars that can be transformed into biofuel for the glucose and xylitol for the xylose. Another pathway could be the alkaline extraction that permits both lignin and hemicelluloses solubilization. This approach leads to a more complex extract increasing the difficulties to produce refine fractions.

The aim of this work was to define a process for the recovery a process inspire from the acid’s one to produce several valuable fraction, hemicelluloses, lignin and monomeric phenolic compounds...
