  1. 21. Making Blue Carbon : Coastal Ecosystems at the Science-Policy Interface

    Författare :Terese Thoni; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; UNFCCC; science-policy interface; Blue Carbon; coastal ecosystems; klimatförändringarna; kustnära ekosystem; blått kol; relationen mellan vetenskap och politik; UNFCCC;

    Sammanfattning : Climate change is a growing threat to mankind. The message from the scientific community is clear: we need to act fast and profoundly. The political response has, however, been slow. The likelihood that we will be able to meet our political climate goals only by reducing emissions is slim. LÄS MER

  3. 22. Manganese Combined Oxides as Oxygen Carriers for Chemical-Looping Combustion

    Författare :Malin Hanning; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon capture; combined oxide; manganese oxide; chemical-looping;

    Sammanfattning : The global emissions of greenhouse gases are increasing and the development of mitigation measures is becoming more important. One of the alternatives proposed is carbon capture and storage, where the carbon dioxide emitted from large point sources is captured, compressed and stored in underground storage sites. LÄS MER

  4. 23. Possibilities and Challenges of Using Combined Manganese Oxides as Oxygen Carriers

    Författare :Malin Hanning; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon capture; combined oxides; manganese oxides; oxygen carriers; manganese ores; chemical-looping combustion;

    Sammanfattning : One alternative proposed to reduce greenhouse gas emissions is carbon capture and storage, where the carbon dioxide emitted from large point sources is captured, compressed and stored in underground geological formations. Many of the largest point sources of carbon dioxide are power plants and industries fuelled by fossil fuels or biomass. LÄS MER

  5. 24. Design and Operation of a 10 kWth Chemical-Looping Combustor for Solid Fuels

    Författare :Nicolas Berguerand; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Fuel Conversion; Chemical-Looping Combustion; Oxygen Carrier; Ilmenite; Carbon Dioxide Capture; Oxygen Transfer; Gas Conversion; Oxygen Demand;

    Sammanfattning : Chemical-looping combustion (CLC) is a new fuel conversion technology with inherent CO2 capture. In this process, the fuel and the combustion air are never mixed and the oxygen is transferred to the fuel via an oxygen carrier in the form of a metal oxide circulating between two reactors, e.g. LÄS MER

  7. 25. Fluidized-Bed Reactor Systems for Chemical-Looping Combustion with Inherent Separation of CO2

    Författare :Eva Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-Looping Combustion; Interconnected Fluidized Beds; Carbon Dioxide Capture;

    Sammanfattning : In chemical-looping combustion (CLC) a gaseous fuel can be burnt with inherent separation of carbon dioxide. The system consists of two reactors, a fuel reactor and an air reactor and an oxygen-carrier in the form of metal oxide particles that transports oxygen from the air to the fuel. LÄS MER
