中文摘要	In this work, three main components (cellulose, hemicellulose, and lignin) of corn stover were fraction-ated effectively by formic acid. The effects of reaction temperature and time on the fractionation wereinvestigated. It was found that the suitable conditions for the fractionation of corn stover were: the formicacid concentration was 88 wt.%, the ratio of solid to liquid was 1:13, and the treatment temperature was80◦C with the duration of 3 h. Under such conditions, the retention yield of cellulose, extraction yields ofhemicellulose and lignin were 89.5%, 79.8% and 65.6%, respectively. Subsequently, the enzymatic hydrol-ysis of the solid residue was conducted by using the enzyme mixture of cellulase (20 FPU/g dry substrate)and -glucosidase (10 IU/g dry substrate). The enzymatic hydrolysis rate of glucan and xylan could reach62.8% and 79.4%, respectively. In addition, to study the property changes of corn stover before and aftertreatment, SEM, XRD and TGA analyses were performed, and the lignin extracted by formic acid was alsocharacterized by TGA and GPC

Subsequently, the enzymatic hydrolysis of the solid residue was conducted by using the enzyme mixture of cellulase (20 FPU/g dry substrate) and beta-glucosidase (10IU/g dry substrate). The enzymatic hydrolysis rate of glucan and xylan could reach 62.8% and 79.4%, respectively. In addition, to study the property changes of corn stover before and after treatment, SEM, XRD and TGA analyses were performed, and the lignin extracted bylformic acid was also characterized by TGA and GPC.
