| Outline of Final Research Achievements |
The hot compressed water treatment was investigated to separate and abstract cellulose fraction from the crop residue biomass such as sunflower stem and rice straw because cellulose can be saccharified enzymatically for the bioethanol feed stock. Aims of this research were to clarify the optimum operation conditions of the hot compressed water treatment such as initial pressure and temperature of the reactor through discussing the effects of these conditions on the component and pellet forming characteristics of the residual solid via the treatment. As results, the followings were obtained experimentally. The particle size of ground biomass affected the yield of glucose significantly. High pressure and high temperature of the hot compressed water treatment resulted over degradation of the biomass to organic acids beyond the cellulose level. The heating temperature of the pelletizer dice influenced much breaking strength and the water resistance of the formed pellet.
