Abstract:
Rice husk is one of lignocellulosic biomass wastes. In this study, effects of hydrolysis condition with dilute acid and mechanochemical treatment on xylose production from rice husk were investigated. The xylan content in the rice husk used in this study was 11.3%, and assuming that this was completely hydrolyzed, 128 g of xylose can be obtained per kg of rice husks. When the hydrolysis of rice husk was conducted for 4 hours with the nitric acid (0.01-0.10 mol/L) at 70-100°C, the highest xylose yield (64.5%) could be obtained with 0.10 mol/L nitric acid at 100°C. By mechanochemical treatment in a planetary ball mill, microfibril structure of rice husk collapsed and became amorphous. The xylose yield reached 93.1%, when the mechanochemically treated rice husk was hydrolyzed with 0.10 mol/L nitric acid at 100°C for 4 hours.
