  1. 1. Petrological, geochemical and structural evidence of fluid-rock interaction in the Siljan Ring

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :William Crang; [2024]
    Nyckelord :methane; hydrothermal fluids; fluid-rock interaction; impact craters; reduction haloes; pyrite preservation; Siljan Ring;

    Sammanfattning : The Siljan Ring in Dalarna, Sweden is the site of the largest meteor impact crater in Europe and has long been a topic of discussion regarding methane production. However, the source of this methane and the timing of production in relation to the impact remain unclear. LÄS MER

  2. 2. Heritability of methane emission in Swedish Red cattle in northern Sweden

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Lucy Chipondoro; [2024]
    Nyckelord :methane emission; heritability; swedish Red cattle; dairy cow;

    Sammanfattning : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. LÄS MER

  3. 3. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Hampus Holmberg; [2023-06-22]
    Nyckelord :;

    Sammanfattning : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. LÄS MER

  4. 4. Biogasproduktion vid samrötning av substrat tillgängliga vid lantbruk : Småskalig rötning vid Lillerudsgymnasiet

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Cecilia Svensson; [2023]
    Nyckelord :Biogas; agriculture;

    Sammanfattning : The world is currently heavily dependent on fossil sources and the use of fossil fuels leads to increased global warming. One of the solutions to this environmental problems is biogas. LÄS MER

  5. 5. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Melker Axelsson; [2023]
    Nyckelord :catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Sammanfattning : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. LÄS MER
