Abstract

Lignin, the most dominant source of renewable aromatic feedstock, exhibits potential for producing bio-based phenolic compounds through fast pyrolysis. The utilization of deep eutectic solvent (DES) for lignin extraction and the pyrolysis of DES-pretreated lignin (DESPL) for phenols production has attracted considerable scholarly interest in recent years. Nonetheless, a comprehensive review focusing on the production of phenolic compounds from DESPL pyrolysis has yet to be published, and the application of this integrated technology is still ongoing. This review aims to fill this gap by elucidating recent advancements in the fractionation of DESPL, with particular emphasis on the influence of DES on the production of phenolic compounds. The performance of recyclable DES in lignin fractionation and the structural properties of DESPL were summarized. Furthermore, the pyrolysis mechanism of lignin was discussed and the potential of DESPL for phenols production was explored. Additionally, relevant computational simulations were systematically summarized to illustrate the enhancement effects of DES pretreatment. This review will provide new insights into the fractionation and valorization of lignin through the application of renewable DES.

深共熔溶剂预处理提高木质素热解制酚类化合物效率的研究进展

木质素是可再生芳香原料的主要来源，具有快速热解生产生物基酚类化合物的潜力。近年来，利用深度共晶溶剂（DES）提取木质素，并将DES预处理木质素（DESPL）热解制备酚类物质引起了学术界的广泛关注。尽管如此，关于从DESPL热解中生产酚类化合物的全面综述尚未发表，并且该集成技术的应用仍在进行中。这篇综述旨在填补这一空白，通过阐明最近的进展，在二苯二酚的分离，特别强调二苯二酚对生产酚类化合物的影响。综述了可回收DES在木质素分馏中的性能及desl的结构特性。探讨了木质素的热解机理，并探讨了其在苯酚生产中的潜力。此外，系统总结了相关的计算模拟，以说明DES预处理的增强效果。本文综述将为可再生DES在木质素分馏和增值方面的应用提供新的见解。

期刊介绍： The Journal of Analytical and Applied Pyrolysis (JAAP) is devoted to the publication of papers dealing with innovative applications of pyrolysis processes, the characterization of products related to pyrolysis reactions, and investigations of reaction mechanism. To be considered by JAAP, a manuscript should present significant progress in these topics. The novelty must be satisfactorily argued in the cover letter. A manuscript with a cover letter to the editor not addressing the novelty is likely to be rejected without review.
