  1. 21. Potential of tall oil pitch as phase change material in lignin-shelled hybrid nanocapsules for thermal energy storage.

    Master-uppsats, Mittuniversitetet/Institutionen för kemiteknik

    Författare :Helena Viberg Nissilä; [2022]
    Nyckelord :phase change materials PCM ; tall oil pitch TOP ; lignin; nanocapsules; hybrid material; thermal storage;

    Sammanfattning : A prospect in utilizing thermal energy in development of energy systems is by the useof phase change materials (PCMs). PCMs are materials that can store and releaseenergy during phase changes, e.g. from solid to liquid. LÄS MER

  3. 22. Wet spinning of carbon fiber precursors from cellulose-lignin blends in a cold NaOH(aq) solvent system

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Landmér Alice; [2022]
    Nyckelord :Carbon fiber; cellulose; cold NaOH aq ; lignin; precursor; sodium hydroxide; solution spinning; wet spinning;

    Sammanfattning : Carbon fiber (CF) is predominantly produced from fossil-based sources and is therefore an area of interest for further development towards a more sustainable society. The purpose of this thesis work was to investigate the possibility of producing precursor fibers (PFs) for CF production from a blend of renewable cellulose andlignin. LÄS MER

  4. 23. Continuous Hydrothermal Co-liquefaction of Biomass : An experimental study on the effects of fuel mixing on the composition and yield of biocrude and hydrochar

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Simon Fridolfsson; [2022]
    Nyckelord :HTL; TGA; SEM EDS; Co-liquefaction effects; GROT; Kraft lignin; Microalgae;

    Sammanfattning : An experimental study on the effect of fuel mixing on the products resulting from hydrothermal liquefaction (HTL) was conducted. The feedstocks used were kraft lignin (KL), GROT (GT) and microalgae cultivated in wastewater (MA). Three sets of mixtures were prepared, each containing two types of feedstocks with a 1:1 ratio: KLGT, MAKL, and MAGT. LÄS MER
