  1. 1. Biokolsanvändningen i Sverige : Vad krävs för att svenska lantbruk, kommuner och trädgårdsindustrin ska börja använda eller utöka sin användning av biokol?

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Författare :Sara Agnesson; [2021]
    Nyckelord :Biochar; sustainable development; climate change; pyrolysis; Biokol; hållbar utveckling; klimatförändringar; pyrolys;

    Sammanfattning : The amount of carbon dioxide, CO2, in the atmosphere is continuously rising due to human emissions caused by combustion of fossil fuels and changing of land use. In a very short time several measures need to be taken in order to reduce the amount of CO2 in the atmosphere and thereby slowing down climate change as much as possible. LÄS MER

    Sammanfattning : On the fourth of November 2016, The Paris Agreement entered into force, stating that nations worldwide should pursue efforts to limit the global temperature increase to 1,5 °C. Since then, the Intergovernmental Panel on Climate Change has specified that carbon dioxide removal, such as biochar sequestration, is necessary to achieve this goal. LÄS MER

  3. 3. Pyrolysis as a business for heat-requiring industries : A case​ study of biochar production in connection to an asphalt plant

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Charlotte Malmén; [2020]
    Nyckelord :pyrolysis; industrial symbiosis; circular economy; renewable energy; asphalt plant; environmental management; sustainable products; biochar;

    Sammanfattning : The expectations on companies to introduce better business models to enhance environmental performance are increasing. Sweden is aiming at becoming climate neutral in 2045 which requires methods to capture and store carbon in addition to decrease emissions. Research has shown that biochar production can be one way to support the target. LÄS MER

  4. 4. Comparative analysis of different pyrolysis techniques by using kraft lignin : Jämförelse mellan olika pyrolys metoder

    Master-uppsats, Karlstads universitet

    Författare :Husam Abbas; [2020]
    Nyckelord :Pyrolysis;

    Sammanfattning : This thesis presents a comparison analysis between various pyrolysis techniques performed on kraft lignin. Numerous literature studies of pyrolysis techniques performed on kraft lignin are reviewed and analysed where different operation temperatures, catalysts and different heating methods are used to pyrolyze kraft lignin.

  5. 5. Carbon materials from biomass for supercapacitors

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Jaskaran Singh Malhotra; [2020]
    Nyckelord :Supercapacitors; Activated Carbon; Energy Storage; Biomass conversion; Electrochemical Energy Storage; Pyrolysis; Superkapacitatorer; Aktivt kol; Energilagring; Biomassa omvandling; Elektrokemisk energilagring; Pyrolys;

    Sammanfattning : The fast pyrolysis plant at RISE – ETC, Piteå produces carbon rich chars in bulk from various sources of biomass as feedstock. These in-house manufactured carbon rich chars were upgraded via pyrolysis as well as chemical activation using KOH to enhance their potential as an electrode material for supercapacitors. LÄS MER
