  1. 1. Measuring copper abundances in the Galactic Bulge

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Nikolei Höglinger; [2024]
    Nyckelord :Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Sammanfattning : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  2. 2. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Simon Dahl; [2023]
    Nyckelord :Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Sammanfattning : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. LÄS MER

  3. 3. 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

  4. 4. Utmaningar och vägen framåt för återbruk av byggnadsmaterial

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Embla Holmquist; Lönegren Alexander; [2023]
    Nyckelord :;

    Sammanfattning : In Sweden, the construction sector accounted for 21% of total greenhouse gas emissions in Sweden in 2020. Sweden's climate goal for reducing these emissions is to have net zero emissions by 2045. LÄS MER

  5. 5. Carbon Capture from Biomass Boiler Flue Gas Emissions using Microalgae : A Case Study

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

    Författare :Graham Kirn; [2023]
    Nyckelord :;

    Sammanfattning : Capture and storage of carbon dioxide (CO2) is expected to play an important role in climate change mitigation efforts intended to limit global warming to 1.5 °C. Bioenergy with carbon capture and storage (BECCS), in which carbon is captured during energy generation from sustainably sourced biomass fuels, is of particular interest in Sweden. LÄS MER
