Abstract: |
The L16（45）orthogonal experiment were carried out with the five factors of the temperature. The pressure, the ratio of feedstock and water, the amount of alkali and the time for the pretreatment of the wheat stalk using the wet-oxidated explosion technology. The optimal wet-oxidated explosion process was obtained with the ratio of feedstock and water 1：0.5, alkali 53g, 0.37×106MPa, 160℃, 20min through the comparison of the sugar yield. The highly saccharification process was obtained through the study on the effect of the different metal ions and PEG on the enzymatic hydrolysis of cellulase. The technology can be up to the saccharification yield 96%. The sugar concentration 150g/L with the good foundation for the bioprocess of cellulose to produce fuel ethanol.
