文阐述了木质生物质转化为主要化学品的类型及其转化途径,提出了从木质生物质转化高附加值化学品的新思路。木质生物质通过一定的降解或分解途径,可产生很多有重要价值的有机小分子化合物,这些有机小分子化合物有葡萄糖、木糖、苯丙烷单体及二聚体,气态小分子如CH4和CO,液态小分子如有机酸、醛、醇,重要基础平台化合物糠醛、乙酰丙酸、木糖醇、乙醇等。通过这些小分子有机化合物的转化,可产生替代石油基产品的高附加值化学品,对可持续发展具有重要意义。
Utilization of biomass resources to develop high-value chemicals is focused on in the present century due to the abatement of the fossil resources. Through pathway of orientated degradation or decomposition of lignocellulosic biomass, many high-value organic substances of small molecules such as glucose, xylose, phenylpropane units and their dimers, gaseous substances such as CH4 and CO, liquid substances such as organic acids, aldehydes, alcohols and other platform chemicals such as furfurals, levulinic acids, xylitols and ethanols can be produced. Furthermore, these small molecules can converse to more high-value chemicals and can replace the petroleum-based chemicals step by step in the future, which are meaningful to the sustainable development of economy and society
