  1. 1. Leveraging green hydrogen to decarbonise the aviation industry : A case study on electrofuels in Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jakob Bergene; Jonathan Bruchhausen; [2023]
    Nyckelord :Electrofuel; e-fuel; electrokerosene; e-kerosene; SAF; sustainable aviation fuel; sustainable aviation; complementarity formation mechanisms; technology value chains; TVC; Techno-economic analysis; TEA; Elektrobränsle; e-bränsle; elektrofotogen; e-fotogen; SAF; sustainable aviation fuel; sustainable aviation; komplementära formationsmekanismer; technology value chains; TVC; Techno-economic analysis; TEA;

    Sammanfattning : For the EU to reach its 2050 climate targets the aviation industry that is highly dependent on fossil fuels needs to drastically reduce its emissions. In the decarbonisation of the aviation industry drop-in sustainable aviation fuels (SAFs) have been identified as a promising solution to abate the industry’s emissions. LÄS MER

  3. 2. The transition of reaction-to-fire behavior from biomass to corresponding biochar

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jacob Johansson; [2023]
    Nyckelord :biochar; biomass; heat release rate; reaction-to-fire;

    Sammanfattning : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. LÄS MER

  4. 3. Lignin Biorefining: Swelling and activation of fibers for lignin extraction

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Ali Al Husseinat; [2023]
    Nyckelord :Biorefining; Carboxymethylation; Extraction; Lignin; Swelling; Bioraffinering; Extraktion; Karboxymetylering; Lignin; Svällning;

    Sammanfattning : I världens omvandling mot en bioekonomi kommer lignocellulosa material spela en stor roll i ersättningen av fossila resurser. Lignin är den mest tillgängliga källan av förnybara och naturligt förekommande aromatiska ämne och den utgör 15–30% av ved. LÄS MER

  5. 4. Increase of biogas production by incorporating residual streams from agriculture

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Stephanie Fjäll; [2022]
    Nyckelord :Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. LÄS MER

  7. 5. Alkaline wet oxidation of biorefinery lignin from wheat straw

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maja Lindblad; [2021]
    Nyckelord :alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

    Sammanfattning : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. LÄS MER
