| Abstract | 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. |
