Abstract
Organosolv is a promising pretreatment for lignocellulose biorefinery on the integrated utilization of full components from lignocellulosic biomass. A highly efficient pretreatment process using methanol/dioxane binary solvent with microwave irradiation is proposed in this study. Poplar wood was fractionated to high quality cellulosic residue, lignin, and monosaccharide derivatives under mild conditions (120 °C, 10 min). The follow-up enzymatic hydrolysis of resulting cellulosic residues achieved almost theoretical glucan conversion over 99%. The 2D-NMR and GPC results showed that the recovered lignin precipitates contain low amount of condensed structures and have relatively narrow molecular weight distributions. The composition analysis of monosaccharide derivatives indicated that the methanol/dioxane solvent tends to convert monosaccharides into glycosides rather than further degradation by-products. The mass balance result estimated that totally 74.2% of raw poplar can be utilized by the pretreatment proposed in this study.
