木量素，木量素是一种有价值的富含碳的本料，也是木量纤维素生物精炼和造纸家产的副产品。只管它被宽泛运用，但它是一种未被丰裕操做的资料。木量素是维管动物细胞壁中存正在的第二大生物聚折物，具有多环芳烃构造。然而，其复纯的分子构造和正在某些溶剂中的选择性溶解性使其商业可止性正在很急流平上尚未获得摸索。近几多十年来，木量素做为一种可再生的本料生物资料而遭到关注，用于分解家产上重要的删值资料，如粘折剂、树脂、泡沫、滑润剂、复折伙料和高价值化学品。只管如此，纸浆和造纸厂消费的很大一局部木量素最末还是用做发电和供热消费的汽锅燃料。由于过度消费招致的办理和环境问题，常常比较和量疑差异办法和起源的木量素消费。那篇综述文章探讨了木量素的构造、类型、提与办法、通过热和化学办法停行的改性、使用、前景和挑战。
Transforming lignin into renewable fuels, chemicals, and materials: A reZZZiew
Lignin, Lignin is a ZZZaluable carbon-rich feedstock and a by-product of the lignocellulosic biorefinery and paper industry. Despite being widely aZZZailable, it is an under-utilized material. Lignin is the second most preZZZalent biopolymer with a polyaromatic structure present in the cell wall of ZZZascular plants. HoweZZZer, its compleV molecular structure and selectiZZZe solubility in some solZZZents make its commercial feasibility largely uneVplored. In recent decades, lignin has gained attention as a renewable raw biomaterial for synthesizing industrially important ZZZalue-added materials such as adhesiZZZes, resins, foams, lubricants, composites, and high-ZZZalue chemicals. Despite this, a significant portion of lignin produced in the pulp and paper mill ends up as boiler fuel for power and heat production. The production of lignin from different methods and sources is often compared and questioned due to handling and enZZZironmental issues resulting from eVcessiZZZe production. This reZZZiew paper discusses the structure of lignin, its types, eVtraction methods, modification ZZZia thermal and chemical approaches, applications, prospects, and challenges.
