Lignocellulosic biomass is the world's most abundant renewable resource. Conversion of lignocellulosic biomass to bioenergy, such as the second generation bioethanol or biobutanol is viable because of its broad availability. Switch grass was developed as a pioneer energy crop in USA with great industrial prospect. It contains about 60% sugars and 18% lignin. An intergrated pretreatment process was...
Fractionation and purification of lignin form pulping black liquor by the organic acid precipitation method was studied in this paper to meet the demands of resource utilization of pulping black liquor. The narrow molecular weigh distribution fraction of lignin could be obtained by citric acid, as shown by gel permeation chromatography (GPC). The effects of reaction temperature, pH of acid evolution...
