Outline of Final Research Achievements

The refinery process of each lignocellulosic component into valuable chemicals via alkaline treatment was developed. The complete hemicellulose solubilization was achieved by hydrothermal treatment, while softening the rigid structure of lignin. Solubilized saccharides were converted into valuable furanic compounds utilizing a microreactor. In the case of alkaline treatment, the high temperature treatment for the simultaneous conversion of cellulose into lactic acid and depolymerization of lignin was favourable as the next fractionation step, rather than the mild selective lignin solubilization. Thus solubilized depolymerized lignin was examined via thermal analysis, which was clarified to be a promising material for resin production.
