  2. 6. Oxygen-carrier materials for chemical-looping combustion

    Author : Paul In-Young Cho; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon Dioxide Capture; and Defluidization.; Carbon Formation; Chemical-Looping Combustion; Oxygen Carrier; CO2 Separation;

    Abstract : For combustion with CO2 capture, chemical-looping combustion (CLC) with inherent separation of CO2 is a promising technology. Two interconnected fluidized beds are used as reactors. In the fuel reactor, a gaseous fuel is oxidized by an oxygen carrier, e.g. READ MORE

  4. 7. Manganese ores as oxygen carriers for chemical-looping combustion

    Author : Sebastian Sundqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-looping with oxygen uncoupling; gaseous fuel; methane; syngas; Chemical-looping combustion; manganese ores; combined oxides; wood char and solid fuels;

    Abstract : Chemical looping combustion (CLC) is a fluidized bed system that circulates metal oxide particles in order to transport oxygen from an air reactor to a fuel reactor. In the fuel reactor a fuel reduces the oxygen carrier while producing CO2 and H2O. The oxygen carrier is then transported back to the air reactor and reoxidized. READ MORE

  5. 8. Mixed Oxide Oxygen Carriers for Chemical-Looping Combustion

    Author : Peter Hallberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-Looping Combustion CLC ; ilmenite; calcium manganite; oxygen carrier; CO2 capture; Chemical-Looping with oxygen uncoupling;

    Abstract : Chemical-Looping Combustion is a promising method for combustion with inherent carbon dioxide capture. Oxygen is provided to the fuel with a solid oxygen carrier. The oxygen carrier is circulated between the reactor for fuel oxidation and another reactor where it is reoxidized with air. A good performing oxygen carrier is vital for this process. READ MORE

  6. 9. Manganese Materials in Solid Fuel Chemical Looping Combustion

    Author : Matthias Schmitz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon capture; CLOU; manganese ores; chemical-looping;

    Abstract : Against the background of rising anthropogenic greenhouse gas emissions, carbon capture andstorage (CCS) has been proposed as a means of mitigating climate change by storing CO2 capturedfrom large point sources in underground geological formations such as aquifers or depleted oilandgas fields. While first generation CCS technologies rely on active gas separation with anassociated energy penalty, chemical looping combustion (CLC) can avoid that step by utilizingsolid metal oxide particles to transfer oxygen from combustion air to fuel, making CO2 captureinherent to the process.
