| 中文摘要: |
| 以广西大宗农业废弃物甘蔗尾为原料,通过多元消晶解聚剂预处理,有效破坏甘蔗尾原料的木质纤维组分间紧密的连接结构,再采用水提醇沉法,高效分离提取得到甘蔗尾半纤维素。通过单因素实验与正交实验,对甘蔗尾半纤维素提取的预处理条件进行优化。结果表明,最佳提取工艺条件为多元消晶解聚剂用量200 μL、甘蔗尾颗粒含水量35%、预处理温度120 ℃、预处理时间3 h。在最佳提取工艺下,甘蔗尾半纤维素的提取率达(14.0±0.5)%;傅里叶变换红外光谱、扫描电子显微镜和热重分析结果表明,多元消晶解聚剂预处理后提取所得甘蔗尾半纤维素的主要化学结构未被破坏,且具有良好的热稳定性。 |
| Abstract: |
| Utilizing sugarcane tops as raw material, a major agricultural waste product in Guangxi, the multi-component decrystallizing depolymerization agent pretreatment effectively disrupted the stable and compact structure of the lignocellulose components in sugarcane tops. Subsequently, the hemicellulose component of sugarcane tops was efficiently separated and extracted via water extraction/alcohol precipitation method. The pretreatment conditions for extracting hemicellulose in the sugarcane tops were optimized through single-factor and orthogonal experiments. The results showed that the optimum extraction process conditions were 200 μL for multi-component decrystallizing depolymerization agent dosage, 35% for sugarcane tops moisture content, 120 ℃ for pretreatment reaction temperature, and 3 h for reaction time. Under the optimized conditions, the extraction yield of hemicellulose from the sugarcane tops reached (14.0±0.5)%. The Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, and Thermogravimetric Analysis indicated that the main chemical structure of the extracted hemicellulose from the sugarcane tops was nearly undamaged after multi-component decrystallizing depolymerization agent pretreatment and it exhibited good thermal stability. |
