| 摘要:本研究通过采用NREL法、硫醇酸解法及高效液相色谱法和离子色谱法等技术，对吉林省5种特色的野生阔叶木主要化学组分及木质纤维素的关键特性进行检测和分析，并基于检测结果对上述植物纤维在造纸及其他领域的应用潜力进行探讨和比较。结果表明，5种木材原料的纤维素含量相近，半纤维素和木质素含量分别为16.68%~24.88%和17.82%~26.15%；分离出的纤维素平均聚合度（DP）为1 021~1 708，半纤维素质均分子质量（Mw）为45.83~73.78 kDa，且以不同类型的木聚糖为主（葡聚糖次之）；酸不溶木质素占比显著，且S/G比例为0.21~3.92。综合分析，山里红在5种阔叶木木材中最适用于制浆造纸领域；花揪树最适用于以木质纤维素为原料的生物质精炼领域。 |
| Abstract:The main chemical composition and key characteristics of lignocelluloses for 5 kinds of wild hardwood species in Jilin Province were characterized using techniques including the National Renewable Energy Laboratory (NREL) method， thioacidolysis， high-performance liquid chromatography (HPLC)， and ion chromatography (IC)， etc. Based on the results， the potential applications of these plant fibers in papermaking and other fields were disscussed and compared. The results showed that the cellulose content of the 5 kinds of wood types was similar， while the hemicellulose and lignin contents ranged from 16.68% to 24.88% and 17.82% to 26.15%， respectively. The average degree of polymerization (DP) of the isolated cellulose was 1 021~1 708， and the weight-average molecular weight (Mw) of hemicellulose was 45.83~73.78 kDa. Hemicellulose primarily consisted of various types of xylans (with glucans being secondary). Acid-insoluble lignin was dominating in the lignin of 5 kinds of hardwood with the S/G ratio ranged from 0.21 to 3.92. Comprehensive analysis indicates that Crataegus pinnatifida (mountain hawthorn) is the most suitable raw material among the 5 kinds of hardwoods in the pulping and papermaking field， while Sorbus pohuashanensis (Sorbus species) is the most suitable one applied in the lignocellulose-based biorefinery field. |
