  1. 1. Magma-Carbonate Interaction and CO2 Release: A Case Study from Carlingford Igneous Centre, Ireland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emelie Lagrosen; [2020]
    Nyckelord :Magma-carbonate interaction; CO2; calc-silicate; skarn; marble; Carlingford; SEM-EDX; XRF; LA-ICP-MS; Magma-karbonat-interaktion; CO2; kalk-silikat; skarn; marmor; Carlingford; SEM-EDX; XRF; LA-ICP-MS;

    Sammanfattning : Magma which intrudes into carbonate rich crust, interacts with the carbonate in several ways, for example by contact metamorphism and formation of marble or by metasomatism resulting in calc-silicate skarn. These processes release volatiles, such as CO2, from the carbonate and might thus cause climate change. LÄS MER

  3. 2. Experimental Study of Mineral Carbonation of Wollastonite for Increased CO2 Uptake

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

    Författare :Dina Babiker; Matilda Ahlstrand; [2019]
    Nyckelord :Concrete; Mineral Carbonation; CO2 Sequestration; Wollastonite; Calcium Silicate; Betong; Mineral karbonatisering CO2-sekvestrering; Wollastonit; Kalciumsilicat;

    Sammanfattning : The cement and concrete industry stand for approximately 8% of the global CO2 emissions. The demand of concrete and cement is expected to increase rapidly with the growing world population and increased urbanization. This makes it of the utmost importance for the industry to try to mitigate its emissions. LÄS MER

  4. 3. Exposure studies of refractory materials for biomass gasification

    Master-uppsats, Institutionen för tillämpad fysik och elektronik

    Författare :Markus Carlborg; [2013]
    Nyckelord :Gasification; biomass; high alumina refractories; alkali; slag;

    Sammanfattning : Gasification is a technology mostly used to convert fossil feedstock to syngas. Biomass could be used as a feedstock instead but that puts different demands on, among other things, the materials in these reactors. LÄS MER

  5. 4. Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Katarina Poll; [2005]
    Nyckelord :sorption; removal; precipitation; reactive filters; wastewater;

    Sammanfattning : In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. LÄS MER

  7. 5. Investigation of a wollastonite occurence in central Sweden

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Anett Elg; [1987]
    Nyckelord :geography; geology; wollastonite; central Sweden; Earth and Environmental Sciences;

    Sammanfattning : The wollastonite occurrence at Hulta is a skarn deposit associated with iron ore within the Leptite Formation of central Sweden. Wollastonite is found in carbonate layers within the leptite and the rocks have been subject to regional metamorphism. These layers are normally approximately 10 cm thick. LÄS MER
