文摘 木质素是一种芳环结构来源丰富且价格低廉的可再生资源。从木质素出发催化解聚制备单酚类高附加值精细化学品和芳香烃烷烃等高品位生物燃料,可以部分替代以化石燃料为原料的生产过程,是生物质资源全组分高效综合利用的重要组成部分。在木质素催化解聚方法中,催化氢解可以直接将木质素转化为低氧含量的液体燃料,在生物燃料利用方面展现出巨大的潜力。本文详细总结了木质素的催化解聚方法,从催化剂类型、溶剂种类、反应机理及催化剂循环使用性等方面介绍了国内外的主要研究进展,着重阐述了木质素催化氢解方法。最后总结了当前木质素催化解聚过程中存在的难题,并对未来的技术发展提出了建议和展望。
其他语种文摘 Lignin is a cheap and renewable resource with rich aromatic units. It can be efficiently transformed into highly value-added fine chemicals such as phenolic monomers and other high-grade biofuels such as arenes and alkanes through catalytic depolymerization methods, which has long been regarded as an important constituent part of biomass resources comprehensive utilization approaches. This process is able to replace the chemicals production from the fossil fuel partly. Among the lignin depolymerization methods, the catalytic hydrogenolysis process can directly convert lignin into liquid fuel with low oxygen contents, and these biofuels show a great potential in the replacement of traditional energy sources. This paper focuses on the catalytic lignin depolymerization methods. The recent progress at home and abroad is reviewed based on the catalysts, solvents, catalysis mechanism and catalyst recyclability. Wherein, the catalytic hydrogenolysis method is emphatically introduced in detail. Furthermore, the current technique challenges during the lignin catalytic depolymerization process are summarized. Many future technologic explorations and suggestions for the efficient application of lignin are proposed.
