FeCl3水热预处理毛竹高效分离半纤维素及高选择性转化木糖的研究
Study on Efficient Separation of Hemicellulose from Mose Bamboo via FeCl3 Hydrothermal Pretreatment and High Selective Conversion to Xylose
摘要
Abstract
In this study,the effects of hydrothermal pretreatment and metal saltsolution-assisted hydrothermal pretreatment on moso bamboo were initially compared.Subsequently,the pretreatment effects of salt solutions consisting of different metal ions(Fe3+and Al3+)and anions(Cl-and SO2-4)were further investigated.Finally,key process parameters,including FeCl3 molar concentration,reaction temperature,treat-ment time,and solid-to-liquid ratio,were systematically optimized.The results demonstrated that the introduction of metal salt solutions more than doubled the hemicellulose removal rate compared with that of hydrothermal pretreatment alone,while also facilitating the conver-sion of hemicellulose into xylose.Owing to its strong Lewis acidity and redox capability,FeCl3 could effectively disrupt the lignocellulosic ar-chitecture of moso bamboo,thereby significantly improving both hemicellulose removal and xylose conversion.Under the optimal conditions(0.075 mol/L FeCl3,150℃,15 min,and liquid ratio of 1∶10),the hemicellulose removal ratio reached 95.47%,the xylose conversion yield was 83.00%,and the generation of the by-product acetic acid was as low as 0.26%.关键词
