Abstract:
A method to recycle aqueous acidic liquor used to form depolymerized cellulose and hemicellulose accompanying cellulose, contained in biomass, by hydrolysis in the aqueous acidic liquor. Cellulose is dissolved in the aqueous acidic liquor and then remains in place to hydrolyze cellulose to form depolymerized cellulose in the aqueous acidic liquor. The depolymerized cellulose, including dextrins, oligosaccharides, and glucose is substantially separated from the aqueous acidic liquor. The separated aqueous acidic liquor is then recycled to dissolve and hydrolyze additional cellulose to form additional depolymerized cellulose.
