Study on Technology of Pre-Hydrolysis Pretreament in Bagasse Dissolving Pulp Preparation Process

Abstract:

This research used bagasse as raw material, through xylanase biological treatment process, preparative bagasse dissolving pulp. The optimum process conditions of sulfuric acid pre-hydrolysis were as below: Acid dosage 0.10%, 150°C, 90min. After pre-hydrolysis, cellulose content of the raw materials increased 18.45%, and pentosan decreased 14.49%. The fiber quality analysis showed fiber length and width were reduced, the tiny fiber content was decreased after acid pre-hydrolysis; HPLC analysis showed the optimum acid pre-hydrolysis process which can reduce the inevitable cellulose degradation effectively,hemicelluloses were hydrolyzed furthest at the same time; FTIR spectrum analysis showed acid pre-hydrolysis process can dissolve a lot of hemicelluloses.
