| Abstract: | In this work, the hydrolysis of corncob was combined with pretreatment by self-synthesized carbon-based solid acid catalyst and subsequent enzymatic hydrolysis of treated residue by cellulase. Through the optimization of the pretreatment reaction condition, the highest xylose yield of 83.4% was obtained. Then, the treated residue was enzymatic hydrolysis by domestic cellulose with the glucose yield of 92.6% was obtained at 48 h and the total yield of reducing sugar up to 88.1% was obtained within these two-step hydrolysis process. |
