甘蔗渣高沸醇预处理过程中木质素和碳水化合物的溶出规律
Dissolution Behaviors of Lignin and Carbohydrate in Bagasse during High Boiling Solvent Pretreatment
摘要
Abstract
This paper reports the kinetic dissolution behaviors of lignin and carbohydrate in bagasse during 1,4-butanediol pretreatment.The results showed the the solvent concentration of 60％ is suitable,which will be economically feasible in consideration of the solvent recycling.The lignin and carbohdrate dissolution undergoes bulk and residual srages,the activation energies of those two stages for lignin are 98.6 and 152.3kJ/mol resoectively,and 117.4and 125.9kJ/mol for carbhydrate respectively.The cellulose will be degraded seriously when rhe content of lignin in the bagasse is reduced to less than 3.2％.This data are of certain guiding significance in optimzing the pretreatment process of bagasse biorefinery using 1,4-butanediol solvent.关键词
