Cotton which is mainly composed of cellulose accounts for about 60 percent of the fiber waste. When the hydrolysis of cotton and the fermentation are performed, the lactic acid which is a raw material of poly-lactic acid is generated. However, general hydrolysis has problems that the 5-hydroxymethyl furfural (HMF) which is generated on hydrolysis disturbed the fermentation and the addition of the catalyst separation process is necessary. Then, the lactic acid is selected as a catalyst to reduce the catalyst separation process because lactic acid is a product on fermentation. Therefore, whether batch type reactor or fixed bed flow reactor is suitable to reduce the HMF on hydrolysis was examined. As a result, it turned out that fixed bed flow reactor is suitable because glucose was flowed out properly to control the production of HMF. Besides yield of glucose is sure to rise if effect of retention time was elucidated.
