农林生物质中半纤维素的高值化利用

摘要

半纤维素是存在于农林生物质中的一种丰富廉价的可再生生物资源，在多个生活应用领域都有重要用途。本文就目前国内外半纤维素高值化利用的主要研究成果进行了综述，从三个方面(膜材料、水凝胶及多糖硫酸酯)综述了半纤维素的应用进展及市场前景。%Hemicelluloses have been pointed out as an immense renewable resource of biopolymers in agricultural and forestry biomass, which have an important use in more than one life application fields. The achievements obtained in the field of high value-added utilization of hemicelluloses at home and abroad were reviewed. The application progress and market situation of hemicelluloses were summarized from three aspects:membrane, hydrogel and sulfated polysaccharides.
