摘要:生物质精炼是有效利用自然界中最丰富且可再生的木质纤维素资源的途径之一，对缓解石油天然气资源日益紧张问题和促进绿色协调可持续发展具有积极重要意义。生物质精炼的方法可分为生物法、物理法、化学法，其中化学法因其速率快、应用广等特点而被广泛研究。化学法中的酸催化法在生物质精炼中占有重要地位。因此，本文将以木质纤维素的酸催化精炼为核心，重点总结和分析了利用固体酸、酸性低共熔溶剂、对甲苯磺酸制备平台化合物、木质素、含木质素的纳米纤维素的研究进展及未来发展趋势。

Abstract:Biomass refining is one of the ways to effectively utilize the most abundant and renewable lignocellulose resources in nature. It is of great significance for alleviating the increasing tension of oil and gas resources and promote green， coordinated and sustainable development. The methods of biomass refining include biological method， physical method and chemical method. Chemical method has been widely studied due to its fast treatment rate and wide application. Acid catalysis method as a chemical method plays an important role in biomass refining. In this paper， the research progress in the preparation of platform compounds， lignin and nanocellulose containing lignin through acid catalyzed refining of lignocellulose was summarized， specifically focusing on the advances on the acid catalyzed refining of lignocellulose with solid acid， acidic deep eutectic solvent and p-toluenesulfonic acid， and the future development direction is also discussed.
