摘要
木质素是自然界中除纤维素外第二大生物质资源,由于其高分子结构中含有丰富的芳环结构及活性含氧基团(如酚羟基等),因此通过解聚生产化工原料和化学品可以部分替代化石能源,有利于缓解能源危机。由于木质素总体利用率较低,如何通过化学方法将其转化为高附加值的化学品是实现木质素高价值化和资源化利用的重要途径之一。综述了木质素解聚转化方法,阐述了催化剂设计,归纳了木质素制备高分子材料的应用优势,提出了木质素磺酸盐通过水滑石催化解聚制取小分子化合物,并以其为原料制备绿色粘合剂的新工艺,并对木质素解聚转化利用的发展方向进行了展望,为木质素高值化和资源化利用提供了理论基础。
Other than cellulose,lignin was the second largest biomass resource in nature.Due to the abundant aromatic units and active group(such as phenolic hydroxyl,etc.)in its’polymer structure,the depolymerization of lignin can partially substituted the fossil resources,which is beneficial to alleviate the energy crisis.At present,the overall utilization of lignin is still low.It was one of the important ways to achieve the high value and resource utilization of lignin by converting it into high value-added chemicals via chemical methods.The utilization of lignin through depolymerization was reviewed,the catalyst design was discussed.Moreover,the advantages of preparation of macromolecule materials by lignin were summarized.On the basis of characteristics of lignin conversion,a new process was proposed for the preparation of green binder by using small molecular compounds prepared from lignin sulfonate by depolymerization using hydrotalcite as catalyst via hydrolysis method.The development direction of depolymerization-conversion utilization technology was forecasted,which would provide a theoretical basis for the high value and the utilization of lignin resources.
