摘要
木质素是自然界中储量巨大且可再生的资源,开展木质素热裂解机理研究有助于木质素基功能性建筑材料的开发。本文在Py-GC/MS上开展了木质素热裂解实验研究,获得了在600°C下反应10 s时的热解产物组成和分布,典型产物为苯酚、愈创木基型酚类和紫丁香基型酚类物质,还有与木质素结构粘连的糖苷键结构的反应产物——呋喃类物质和碳直链物质。结合产物分析推演了基于特征官能团的木质素热裂解机理途径,有助于深入了解木质素的热化学转化路径。
Lignin is one of the most abundant sustainable re-sources in nature. The mechanism research on lignin pyrolysiswill help the development of lignin - based functional buildingmaterials. The experiments were carried out on Py - GC/MS, andthe composition and distribution of pyrolysis products were ob-tained at 600℃ holding for 10s. Typical products were phenols,guaiacols and syringols. And other products such as furans andlinear carbon materials were also formed due to the existence ofglucosidic bonds linkage structure.
