摘要

木材的生物回收包括许多不同的过程,目的是完全利用主要产品和副产品。从木材中完全分离C5和C6糖及其进一步利用目前正引起全世界的关注。C5糖可直接催化转化为糠醛或单糖水溶液进行进一步水解处理。所得木质纤维素可用于热化学热解(350-400℃)合成左旋葡聚糖。热解过程中形成的生物炭和左旋葡聚糖分离后的液体残渣是副产物,可以作为前体得到有价值的产品——用于超级电容器电极和燃料电池催化剂的活性炭复合材料。

Utilization of Levoglucosan Production By-Products
Biorecycling of wood includes many different processes aimed at the complete utilization of the main and by-products. The complete isolation of C5 and C6 sugars from wood and their further use is currently attracting attention worldwide. The C5 sugars can be catalytically converted directly into furfural or into monosaccharides’ aqueous solution for further hydrolytic treatment. The resulting lignocellulose can be used in thermochemical pyrolysis (350-400°C) for the synthesis of levoglucosan. The biochar formed during pyrolysis and the liquid residue after the isolation of levoglucosan are by-products and can be used as precursors to obtain valuable products – activated carbon composites for supercapacitor electrodes and catalysts in fuel cells.
