Conversion Pattern of Lignocellulosics in the Phase-Separation System
In recent years, considerable efforts have been devoted to utilize biomaterials placing petroleum for chemical feedstock. It is of importance to produce biodegradable materials from renewable resources such as lignocellulosics. In this concern, wood is the most important resource because wood can build up large storage of carbon dioxide. However, the wood refining must be done before the use in chemical feedstock. Separating lignocellulosic components is extremely difficult since the lignocellulosics have the interpenetrating polymer network structure composed of lignin, hemicellulose and cellulose . So far the lignocellulosics have been digested with strong alkaline agents for paper making or pre-hydrolyzed with strong acid for ethanol fermentation. During these treatments, lignin are subjected to very complicate modifications [2, 3, 4] and deactivated to be treated as a waste.
