  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. Oxygen carrier aided combustion: Implementation of oxygen carriers to existing industrial settings

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Angelica Gyllén; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ilmenite; Oxygen carrier aided combustion; Fluidized-bed; Biomass;

    Sammanfattning : Utilization of biomass and waste to produce heat and power is necessary for a sustainable future energy mix. Thermal conversion of biomass is considered to yield CO2 neutral emissions and the utilization of waste reduces its volumes in a world struggling to dispose of ever-increasing amounts. LÄS MER
