Abstract

Despite lignin having long been viewed as an impediment to the processing of biomass for the production of paper, biofuels, and high-value chemicals, the valorization of lignin to fuels, chemicals, and materials is now clearly recognized as a critical element for the lignocellulosic bioeconomy. However, the intended application for lignin will likely require a preferred lignin composition and form. To that end, effective lignin valorization will require the integration of plant biology, providing optimal feedstocks, with chemical process engineering, providing efficient lignin transformations. Recent advances in our understanding of lignin biosynthesis have shown that lignin structure is extremely diverse and potentially tunable, while simultaneous developments in lignin refining have resulted in the development of several processes that are more agnostic to lignin composition. Here, we review the interface between in planta lignin design and lignin processing and discuss the advances necessary for lignin valorization to become a feature of advanced biorefining.

通过植物生物学和生物炼制的综合进展实现木质素的价值化。
尽管木质素长期以来一直被视为阻碍生物质加工以生产纸张、生物燃料和高价值化学品的因素,但现在人们已清楚地认识到,将木质素转化为燃料、化学品和材料是木质纤维素生物经济的关键要素。然而,木质素的预期应用可能需要首选的木质素成分和形式。为此,有效的木质素价值化需要将提供最佳原料的植物生物学与提供高效木质素转化的化学工艺工程相结合。最近,我们对木质素生物合成的认识取得了进展,这表明木质素的结构极其多样,具有潜在的可调性,而与此同时,木质素提纯技术的发展也开发出了几种对木质素成分更不敏感的工艺。在此,我们回顾了植物木质素设计与木质素加工之间的界面,并讨论了木质素价值化成为先进生物炼制的一个特征所需的进步。
