dc.description.abstract | Dilute acid fractionation of barley straw improves dissolving hemicellulose fraction of the straw, while leaving the cellulose more reactive and accessible to enzyme as a strategy of pretreatment. To characterize the fractionation process, the effects of the acid concentration, temperature and reaction time on the hemicellulose removal as well as on the formation of by-products (furfural, 5-hydroxymethylfurfural and acetic acid) were investigated. The optimum fractionation conditions of barley straw were 1% (w/v) concentration of sulfuric acid, 158 C of reaction temperature and 15 min of reaction time. Under the optimum conditions, 87% of xylan was hydrolyzed and recovered in liquid hydrolyzate, which was 7% higher than that of the predicted yield. The hydrolyzate contained glucose 2.44 g/L, arabinose 1.70 g/L, xylose 13.41 g/L, acetic acid 1.55 g/L, levulinic acid 0.03 g/L, 5-HMF 0.03 g/L and furfural 0.75 g/L. | - |
