Cellulose saccharification is the most important core-technology for biomass conversion and effective utilization. Recently, acid hydrolysis processes that have already been put to practical use, however, it's not satisfactory in terms of profitability owing to several technical problems. Therefore, in order to develop another process, we have performed several fundamental experiments by using cellulose microcrystalline. In the case of a 5mL scale, hydrolysis by hot compressed-water at 260℃ showed a saccharification ratio (hydrolysis conversion of cellulose to glucose) of only 15%, but improved to 25% by addition of a small amount of acetic acid and substitution of the internal air of reaction pipe to nitrogen gas.
