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

    Author : Dazheng Jing; Chalmers University of Technology; []
    Keywords : Chemical-looping with oxygen uncoupling; Combined manganese oxides; Chemical-looping combustion; CuO-based oxygen carrier; Oxygen carrier;

    Abstract : 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. READ MORE

  2. 2. Oxygen Carriers Materials for Chemical-Looping Technologies

    Author : Muhammad Qamar Ul Islam Zafar; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Natural gas; Reaction kinetics; Oxygen carriers; Chemical-looping reforming; TGA; Chemical-looping combustion; CO2; Metal oxides;

    Abstract : Carbon dioxide is the gas which contributes most to the greenhouse effect. It is released in large quantities from fossil fuel-based power plants around the world. It is generally accepted that a rapid decrease in the emissions of carbon dioxide is needed. READ MORE

  3. 3. Capture of CO2 from solid fuels using Chemical-Looping Combustion and Chemical-Looping Oxygen Uncoupling

    Author : Henrik Leion; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; chemical-looping with oxygen uncoupling; fluidized bed; gasification; CO2-capture; biofuels; oxygen carrier; chemical looping combustion; CLOU; petroleum coke; coal; CLC;

    Abstract : In order to meet the global demand of CO2 neutral energy, chemical-looping combustion could play an important role. Oxygen can be transferred from the combustion air to the fuel by means of oxygen carrying metal oxide particles circulating between two reactors, an air- and a fuel reactor. READ MORE

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

    Author : Mehdi Arjmand; Chalmers University of Technology; []
    Keywords : chemical-looping combustion CLC ; chemical-looping with oxygen uncoupling CLOU ; copper; CO2-capture; kinetic; oxygen carrier;

    Abstract : 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.

  5. 5. Oxygen-carrier materials for chemical-looping combustion

    Author : Paul In-Young Cho; Chalmers University of Technology; []
    Keywords : 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
