Abstract

Sugarcane bagasse was refined into cellulose, hemicellulose, and lignin using an ethanol-based organosolv technique. The hydrothermal carbonization (HTC) reactions were applied for bagasse and its two components cellulose and lignin. Based on GC-MS analysis, 32 (13+19) organic byproducts were derived from cellulose and lignin, more than the 22 byproducts from bagasse. Particularly, more valuable catechol products were obtained from lignin with 56.8% share in the total GC-MS integral area, much higher than the 2.263% share in the GC-MS integral areas of bagasse. The organic byproducts from lignin make up more than half of the total mass of lignin, indicating that lignin is a chemical treasure storage. In general, bio-refinery and HTC are two effective techniques for the valorization of bagasse and other biomass materials from agriculture and forest industry. HTC could convert the inferior biomass to superior biofuel with higher energy quantity of combustion, at the same time many valuable organic byproducts are produced. Bio-refinery could promote the HTC reaction of biomass more effective. With the help of bio-refinery and HTC, bagasse and other biomass materials are not only the sustainable energy resource, but also the renewable and environment friendly chemical materials, the best alternatives for petroleum, coal and natural gas.

摘要

甘蔗渣经乙醇基有机溶剂法制浆精制为纤维素、半纤维素和木质素。采用水热碳化（HTC）技术对甘蔗渣及其两种成分纤维素和木质素进行了反应。基于 GC-MS 分析，从纤维素和木质素中衍生出 32 种（13+19）有机副产物，多于从甘蔗渣中获得的 22 种副产物。特别是木质素获得了更多有价值的邻苯二酚类产物，其在总 GC-MS 积分面积中的占比为 56.8%，远高于甘蔗渣中 GC-MS 积分面积的 2.263%。木质素中的有机副产物占木质素总质量的一半以上，这表明木质素是一种化学宝库。总的来说，生物炼制和 HTC 是甘蔗渣和其他农林生物质材料增值的两种有效技术。HTC 可以将劣质生物质转化为具有更高燃烧能量的优质生物燃料，同时还会产生许多有价值的有机副产物。生物炼制可以更有效地促进生物质的 HTC 反应。在生物炼制和 HTC 的帮助下，甘蔗渣和其他生物质材料不仅是可持续的能源资源，还是可再生和环境友好的化学材料，是石油、煤炭和天然气的最佳替代品。
