水热法是一种将木质纤维素资源转化为生物燃料和高附加值化学品的绿色工艺。木质生物质的分级允许探索综合林业生物炼制的概念。半纤维素的水解产生寡糖、戊糖（木糖和阿拉伯糖）、己糖（葡萄糖、甘露糖和半乳糖）、酸（乙酸、甲酸和乙酰丙酸）和呋喃（糠醛和5-羟甲基糠醛），以及在苛刻条件下作为副产物的所得不溶性腐黑物。本章重点介绍了各种木质纤维素生物质水热处理的最新研究成果，包括水热预处理的基本原理以及水热预处理过程中的机理和动力学研究，特别是水热处理前后半纤维素的分析和表征。
Hydrothermal process is a potential technology to convert lignocellulosic resources into biofuels and value-added chemicals in a green fashion. Fractionation of woody biomass allows the exploration of the concept of integrated forestry biorefinery. The hydrolysis of hemicellulose produces oligosaccharides, pentose (xylose and arabinose), hexose (glucose, mannose, and galactose), acids (acetic acid, formic acid, and levulinic acid), and furans (furfural and 5-hydroxymethylfurfural), as well as resulting insoluble humins as by-products under harsh conditions. This chapter highlights recent results on hydrothermal processing of various lignocellulosic biomasses, including fundamentals of hydrothermal pretreatment and mechanistic and kinetic studies in such process, especially in analysis and characterization of hemicelluloses before and after hydrothermal processing.
