  4. 2. Biosynthesis, interactions, and structure of native lignin

    Author : Ioanna Sapouna; Lauren S. McKee; Francisco Vilaplana; Claudia Crestini; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lignin; biomass valorization; extraction; tissue culture; lignin nanoparticles; wood aerogels; lignin; biomassavalorisering; extraktion; vävnadsodling; lignin nanopartiklar; trä aerogeler; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. READ MORE

  5. 3. Microwave-assisted transformations of lignin for value-added material applications

    Author : Jenevieve G. Yao; Minna Hakkarainen; Karin Odelius; Monika Österberg; KTH; []
    Keywords : lignin; microwave-assisted processes; organosolv fractionation; esterification; fused filament fabrication; digital light processing; lignin; mikrovågsassisterade strategier; organosolv-fraktionering; förestring; additiv tillverkning; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The chemical diversity and structural complexity of lignin, an abundant biopolymer found in vascular plants, present a multitude of opportunities for the modification and fine-tuning of its properties to suit downstream demands. In this thesis, microwave-assisted strategies were explored as efficient and environment-friendly pathways for lignin valorization towards value-added material applications. READ MORE

  6. 4. Towards a pure kraft lignin

    Author : Rufus Ziesig; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost; black liquor; lignin; impurities; purification; carbohydrate; inorganics; precipitation;

    Abstract : The most widely used production method for paper pulp in the world is kraft pulping. In chemical pulping the polymer, lignin, which binds the wood fibres together, is partly depolymerized. This allows the wood fibres to be separated from each other. READ MORE

  7. 5. Lignin Conversion to Value-Added Small-Molecule Chemicals : Towards Integrated Forest Biorefineries

    Author : Omar Y. Abdelaziz; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aromatic monomers; biorefinery; catalysis; kraft lignin; lignin depolymerization; lignin valorization; microbial conversion; renewable chemicals; techno-economic analysis;

    Abstract : Lignin is the most abundant aromatic biopolymer on Earth and has significant potential as a feedstock for industrial use. Due to its intrinsic heterogeneity and recalcitrance, lignin has been regarded as a low-value side-product in the pulp and paper industry and in second-generation biorefineries. READ MORE
