摘要:木质素是迄今为止自然界中由芳香单元组成的最丰富的可再生资源。但其分子结构十分复杂,很难高效利用,能够真正应用于大规模生产的产品还很少。在当今全球化石油资源日益短缺而期以生物质资源对其有效取代的背景下,如何将木质素降解为小分子化合物是一项十分有意义的研究工作。为此,文中对木质素的化学催化降解方法进行了综述,包括木质素热裂解法、催化还原降解、催化氧化降解,讨论了其降解机理,并对其发展趋势进行了展望。开发低成本、选择性好、高效率的催化降解体系将仍然是木质素高值应用的重要方向之一。
Lignin is the most abundant renewable resource composed of aromatic units in nature.It is difficult to efficiently use it because of its complicated molecular structure.And there are few examples that can be applied for mass production.In the context of the increasing shortage of global stone resources and the effective replacement of biomass resources,how to degrade lignin into small molecule compounds is a very meaningful research work.In this paper,the chemical catalytic degradation of lignin was reviewed,including lignin thermal cracking,catalytic reduction degradation,catalytic oxidative degradation.Its degradation mechanism was discussed and its development trend was prospected,developing low-cost,selective,and efficient catalytic degradation systems is one of the important directions for high-value applications of lignin.
