Prehydrolysis achieves higher organosolv delignification

摘要: Presented is the investigation of water pretreatment southern yellow pine meal and its effects on subsequent organsolv treatment pulp with 50:50 n-butanol:water. Lignin removal enhanced no additional loss in residual pulp. Values for lignin conversion 31% (at 180 degrees C) 34% 200 without are increased to 33% 37% when a used. Holdup times were varied from 0 3 hr. Kinetic analysis data shows that weight due wood initially controlled by hemicellulose hydrolysis shift beta-cellulose later periods treatment. (Refs. 11).
