Abstract
The present invention relates to a method of producing cellulosic sugar from biomass by effective impurity removal and sugar separation, and more particularly to a method for producing cellulosic sugar from biomass. The method includes pretreating the biomass so as to be separated into a solid and a liquid; subjecting the separated liquid to monomerization, concentration and adsorption processes, thereby obtaining xylose; and subjecting the separated solid to second pretreatment, saccharification and lignin separation processes, thereby obtaining glucose. The method allows fermentation inhibitory substances to be removed from pretreated biomass in a cost- and energy-effective process, and is useful for effective production of cellulosic sugar.
