摘要:Lignocellulosic biomass is considered the most biorenewable resource available for human, with well known uses for biofuels, biopolymers, and green chemicals. It is primarily composed of cellulose, hemicellulose, and lignin. The different structures and different properties of these three polymeric components in lignocellulosic biomass result in different applications. Thus, from a holistic perspective for lignocellulosic biomass utilization, the valorization of all lignocellulosic biomass components would fully exploit the potential of biomass in the development of a system which maximizes value-added products and achieve the greatest economic gain. We have developed a novel method for the fractionation and separation of lignocellulosic biomass components. This method allows the fractionation of lignocellulosic biomass into three fractions (cellulosic fibers, lignin fraction, and hemicellulose fraction) in a closed system with microwave treatment. This method also allows the fractionation reaction to be carried out under relatively low temperature (under 150oC) with short reaction time (7-10min). The processes involved in this method result in significant energy savings. Also, no toxic chemicals are used in the fractionation process. The obtained fractions had considerable accessibility for subsequent operations.
