Abstract
A economically viable method for producing sugars using concentrated acid hydrolysis of biomass containing cellulose and hemicellulose is disclosed. The cellulose and hemicellulose in the biomass is first decrystallized and then hydrolyzed to produce a hydrolysate containing both sugars and acid. Silica and silicates present in the biomass can then be removed for further processing. The remaining solids are then subjected to a second decrystallization if necessary and a second hydrolyzation to optimize the sugar yields.
