摘要：
Objective: The development of a solvolysis process by combining microwave heating and glycerol is a promising method to enhance the economic viability of biorefinery. The application of this technology on the pretreatment of lignocellulosic biomass is of great significance. Method: The liquefaction treatment of Populus alba ×P. glandulosa 84 K, Larix kaempferi, Phyllostachys viridis and Panicum virgatum was carried out by microwave liquefaction method. The products were divided into liquid and solid cellulose components. Using cellulose as raw material, the cellulose components were comprehensively characterized. Result: The chemical analysis result showed that the cellulose fiber had high glucan content. Infrared spectroscopy showed that the signals of lignin and hemicelluloses gradually weakened, further confirming the effective removal of hemicelluloses and lignin in the liquefaction treatment. The result of XRD analysis showed that the cellulose fibers had high crystallinity and large surface area. Conclusion: Compared with the original lignocellulosic biomass, the enzymolysis saccharification efficiency of the cellulose fiber of four kinds of raw materials was not improved to a certain degree, indicating the potential of cellulose fiber in liquefied solid product in the preparation of fuel ethanol. © 2019, Editorial Department of Scientia Silvae Sinicae.
