Abstract:
Both pretreatment of lignocellulose and its saccharification process are treated with ultrasonic wave.The morphology,structure and crystal performance of the original and treated lignocellulose sample were characterized by SEM and FTIR.Moreover,the changes of raw materials caused by different pretreatment ways and the affect of saccharification rate brought about by ultrasonic wave were also studied.The result shows that the ultrasonic wave decreases the crystallinity of lignocellulose destroying the intermolecular hydrogen bonding effectively and improves the degradation rate of lignin and the saccharification rate of zymohydrolysis availably.The mechanism of activation of ultrasonic wave in zymohydrolysis process was discussed primarily.
