摘要	Traditional liquid hot water pretreatment (LHWP) has a high water consumption, a high reaction temperature, and low lignin removal, making it unsuitable for industrial applications of biomass conversion. In this study, we developed a new phase-exchange solvent pretreatment (PESP) based on the varied phase composition of furfural (FF)-water at different temperatures. Substitution of water with FF had no significant influence on xylan hydrolysis, but it improved the mass transfer performance. At the optimum conditions of 180 degrees C, an FF:water ratio of 30:70 (v/v), a solid:liquid ratio of 1:8 (w/v), and 0.2 wt % sulfuric acid for 30 min, the PESP of energy sorghum achieved a 74.98% total xylose yield and removed 85.08% of the lignin, while there was a selective distribution of sugar and lignin in the aqueous and organic phases, respectively. Moreover, 99.58% of the cellulase enzyme digestibility and 94.02% of the total sugar recovery were achieved after 72 h. This unusually high enzymatic digestibility could be attributed to the physicochemical changes in the substrate after the pretreatment. When compared with a traditional LHWP (5% solid loading), the water consumption decreased by approximately 72% and the lignin removal increased by 60.74%. These results demonstrate that PESP is a promising technology for biorefining lignocellulosic biomass with high efficiency and low energy consumption.
