title: A new method of utilizing rice husk: consecutively preparing D-xylose, organosolv lignin, ethanol and amorphous superfine silica.
abstract: Rice husk is an abundant agricultural by-product with the annual output of 120 and 40 million tons in the world and China, respectively. The common disposal method of rice husk in China has caused the pollution. This manuscript deals with a new method of comprehensively utilizing rice husk, by which hazardous materials are avoided to release. 100.3, 219.4, 50.1 and 170.5 g of D-xylose, organosolv lignin, ethanol and superfine silica are consecutively prepared from 1000 g of rice husk. This new method is helpful to resolving the problem of pollution and waste aroused by rice husk.
