Optimization of The-Hydrolysis Parameters of Dissolving Pulp of Fast-Growing Poplar Producing

Abstract:

As textile industrial and glass paper-making materials, dissolving pulps are scarce in China and a great deal of dissolving pulps are imported in the recent years. Currently different fiber materials are tried to produce dissolving pulp in China. In this research work the hydrolysis parameters of the fast-growing poplar based dissolving pulp producing were investigated .And the chemical composition of pulp after hydrolysis were also analyzed, the experimental results showed that the optimal hydrolysis conditions were acid dosage in the range from 0.015% to 0.035%, wood-to-liquor ratio 1:6.5, and the temperature 130 °C. The pentosan content of the pulp after hydrolysis in this hydrolysis conditions was in range of 0.62%-23.16%, which decreased by 23.01%. And the cellulose content slightly changed.
