Lignin Extraction by Using Two-Step Fractionation: A Review

Molecules, Год журнала: 2023, Номер 29(1), С. 98 - 98

Опубликована: Дек. 22, 2023

Lignocellulosic biomass represents the most abundant renewable carbon source on earth and is already used for energy biofuel production. The pivotal step in conversion process involving lignocellulosic pretreatment, which aims to disrupt lignocellulose matrix. For effective a comprehensive understanding of intricate structure its compositional properties during component disintegration subsequent essential. presence lignin-carbohydrate complexes covalent interactions between them within matrix confers distinctively labile nature hemicellulose. Meanwhile, recalcitrant characteristics lignin pose challenges fractionation process, particularly delignification. Delignification critical that directly impacts purity facilitates breakdown bonds surrounding cellulose. This article discusses two-step approach efficient extraction, providing viable paths lignin-based valorization described literature. allows creation individual streams each component, tailored extract their corresponding compounds.

Kraft (Nano)Lignin as Reactive Additive in Epoxy Polymer Bio-Composites

Polymers, Год журнала: 2024, Номер 16(4), С. 553 - 553

Опубликована: Фев. 18, 2024

The demand for high-performance bio-based materials towards achieving more sustainable manufacturing and circular economy models is growing significantly. Kraft lignin (KL) an abundant highly functional aromatic/phenolic biopolymer, being the main side product of pulp paper industry, as well recent 2nd generation biorefineries. In this study, KL was incorporated into a glassy epoxy system based on diglycidyl ether bisphenol A (DGEBA) amine curing agent (Jeffamine D-230), utilized partial replacement DGEBA prepolymer or reactive additive. D-230 by pristine (unmodified) up to 14 wt.% achieved while KL–epoxy composites with 30 exhibited similar thermo-mechanical properties substantially enhanced antioxidant compared neat polymer. Additionally, effect particle size investigated. Ball-milled kraft (BMKL, 10 μm) nano-lignin (NLH, 220 nm) were, respectively, obtained after ball milling ultrasonication were studied additives in same system. Significantly improved dispersion obtained, mainly nano-lignin, which fully transparent lignin–epoxy higher tensile strength, storage modulus glass transition temperature, even at loadings. Lastly, glycidylized (GKL) prepolymer, 38 fossil-based DGEBA. GKL transparency. All lignins extensively characterized using NMR, TGA, GPC, DLS techniques correlate justify polymer characterization results.

Bio�Cbased polymers from lignin

The Innovation Materials, Год журнала: 2024, Номер 2(2), С. 100062 - 100062

Опубликована: Янв. 1, 2024

<p>Lignin, the most abundant natural aromatic compound on earth, offers valuable resources for development of bio–based polymers. In recent years, a plethora diverse polymer materials has been reported using either separated lignin or lignin–derived monomers. this review, we present comprehensive summary achievements and compare these two well–known strategies. While utilizing directly as starting advantages in terms cost–effectiveness wider options, employing monomers suffer from higher costs limited structural variety. However, well–defined structure lignin-derived monomers, retention functional group characteristics make promising strategy future applications. Through review paper, aim to inspire more researchers material science focus lignin—an intriguing emerging carbon-neutral biomaterial.</p>
