摘要:本研究首先对比了水热预处理与金属盐溶液水热预处理毛竹的效果，在此基础上，进一步分析了不同金属离子（Fe3+与Al3+）与阴离子（Cl-与SO42- ）组合盐溶液的预处理效果。最后，系统优化了FeCl3溶液物质的量浓度、反应温度、处理时间及液比等关键工艺参数。结果表明，引入金属盐溶液后，半纤维素脱除率提升至水热预处理的约2倍以上，且有利于半纤维素向木糖的转化。FeCl3凭借其较强的路易斯酸性与氧化还原能力，可有效破坏毛竹的木质纤维结构，显著提升半纤维素脱除率与木糖转化率。在最优条件（0.075 mol/L FeCl3、150 ℃、15 min、液比1∶10）下，半纤维素脱除率达95.47%，木糖转化率为83.00%，且副产物乙酸生成量低至0.26%。
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 SO42- ) were further investigated. Finally， key process parameters， including FeCl3 molar concentration， reaction temperature， treatment 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 conversion of hemicellulose into xylose. Owing to its strong Lewis acidity and redox capability， FeCl3 could effectively disrupt the lignocellulosic architecture 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%.
