The hemicellulosic fraction recovery is of interest for integrated processes in biorefineries, considering the possibility of high economic value products produced from their structural compounds of this polysaccharide. However, to perform an efficient recovery, it is necessary to use biomass fractionation techniques, and hydrothermal pretreatment is highlighted as a valuable technique in the hemicellulose recovery by applying high temperatures and pressure, causing dissolution of the structure. Considering the possibility of this pretreatment technique for current approaches to hemicellulose recovery, this article aimed to explore the relevance of hydrothermal pretreatment techniques (sub and supercritical water) as a strategy for recovering the hemicellulosic fraction from lignocellulosic biomass. Discussions about potential products to be generated, current market profile, and perspectives and challenges of applying the technique are also addressed.
考虑到从这种多糖的结构化合物中生产高经济价值产品的可能性，半纤维素级分的回收对于生物精炼厂的综合工艺而言具有重要意义。然而，要实现高效回收，就必须采用生物质分馏技术，而水热预处理作为一种通过施加高温高压使结构溶解从而在半纤维素回收中具有重要价值的技术备受关注。鉴于这种预处理技术在当前半纤维素回收方法中的可能性，本文旨在探讨水热预处理技术（亚临界水和超临界水）作为从木质纤维素生物质中回收半纤维素级分的一种策略的相关性。同时还讨论了可能产生的潜在产品、当前市场概况以及应用该技术的前景和挑战。
