| Abstract: |
| Kinetic model of hemicellulose dissolution during water prehydrolysis of phyllostachys heterocyclava under the conditions of temperature 140～170℃, reaction time of the temperature 0～300 min and ratio of liquid to solid 10∶1 was studied. All experimental data were fitted to get the kinetic parameters. The results showed that the hydrolysis reaction of hemicellulose was clearly divided into fast and slow stages from 140℃ to 170℃, the activation energys were 83.29 kJ/mol and 138.79 kJ/mol respectively. The reaction temperature had significant influence on the water prehydrolysis process, which must be strictly controlled to achieve the purpose of removing hemicellulose in a short time and reducing the degradation of cellulose. |
