  1. 1. Innovative Oxygen Carriers for Chemical-looping Combustion

    Författare :Dazheng Jing; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-looping with oxygen uncoupling; Combined manganese oxides; Chemical-looping combustion; CuO-based oxygen carrier; Oxygen carrier;

    Sammanfattning : Chemical-looping combustion (CLC) and chemical-looping with oxygen uncoupling (CLOU) are combustion technologies where carbon dioxide is inherently obtained in pure form without any gas separation step. In the processes, fuel is introduced to the fuel reactor and combustion air is introduced to the air reactor. LÄS MER

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

    Författare :Nicolas Berguerand; [2009]
    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

  3. 3. Development and Characterisation of Oxygen-Carrier Materials for Chemical-Looping Combustion

    Författare :Paul In-Young Cho; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxygen carrier; defluidization; CO2 separation; carbon dioxide capture; carbon formation; chemical-looping combustion;

    Sammanfattning : 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. LÄS MER

  4. 4. Mixed Oxide Oxygen Carriers for Chemical-Looping Combustion

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Peter Hallberg; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-Looping Combustion CLC ; ilmenite; calcium manganite; oxygen carrier; CO2 capture; Chemical-Looping with oxygen uncoupling;

    Sammanfattning : 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. LÄS MER

  5. 5. Copper in Chemical-Looping Combustion (CLC) and Chemical-Looping with Oxygen Uncoupling (CLOU)

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Mehdi Arjmand; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping combustion CLC ; chemical-looping with oxygen uncoupling CLOU ; copper; CO2-capture; kinetic; oxygen carrier;

    Sammanfattning : The chemical-looping combustion (CLC) and chemical-looping with oxygen uncoupling (CLOU) processes are attractive solutions for efficient combustion with inherent separation of carbon dioxide. These processes use a metal oxide as an oxygen carrier to transfer oxygen from an air to a fuel reactor where the fuel, or gasification products of the fuel, reacts with the oxygen carrier. LÄS MER
