| Abstract: | The pretreatment conditions for cassava stalk by diluted acid were studied.The effects of the liquid-solid ratio,reaction temperature,HCl volume fraction and reaction time on the concentration of reducing sugar of the hydrolysate were examined.It had been observed that the concentration of reducing sugar was 9.35 g·L-1 under the optimum pretreatment conditions as follows:liquid-solid ratio was 40∶1,reaction temperature was 100℃,HCl volume fraction was 3%,reaction time was 5 h. |
