  1. 21. Investigation of Ilmenite from Oxygen Carrier Aided Combustion: Sulfur Interactions and Recovery of Elements

    Författare :Mariane Vigoureux; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Oxygen Carrier Aided Combustion; Circulating-Fluidized Bed; Ash; Sulfate process; Sulfur; Biomass; Ilmenite; Leaching;

    Sammanfattning : Oxygen- Carrier- Aided Combustion (OCAC) is a promising technology for the combustion of solid heterogeneous fuels such as biomass and waste in fluidized-bed (FB) units. In OCAC the conventional bed material silica sand is replaced by an oxygen carrier (OC). Replacing the bed material with an OC has many advantages. LÄS MER

  4. 23. Chemical-Looping Combustion with Liquid Fuel — Operation in a 300W Chemical-Looping Combustor

    Författare :Patrick Moldenhauer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; oxygen carrier; kerosene; circulated fluidized bed CFB ; liquid fuel; CO2 capture; chemical-looping combustion CLC ;

    Sammanfattning : Chemical-looping combustion (CLC) is a promising technology for future energy production based on combustion of fossil fuel with inherent CO2 separation. In comparison to other carbon capture technologies there is no need for energy demanding gas separation using CLC in order to obtain pure CO2. LÄS MER

  5. 24. Chemical-Looping Combustion with Solid Fuels

    Författare :Henrik Leion; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; petroleum coke; fluidized bed; oxygen carrier; ilmenite; volatiles; gasification; sulphur dioxide; coal; iron oxide; chemical looping combustion; CLC;

    Sammanfattning : In order to meet the global demand of CO2 neutral energy production, chemical-looping combustion could play an important role. With this technique it is possible to capture CO2 without an excessive energy penalty. LÄS MER

  7. 25. CO2 Capture using Chemical-Looping Combustion – Operational Experience with Gaseous and Solid Fuels

    Författare :Carl Johan Linderholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nickel oxide; coal; natural gas; chemical-looping combustion CLC ; oxygen carrier; CO2 capture; manganese ore; interconnected fluidized beds; ilmenite;

    Sammanfattning : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion (CLC) is an unmixed combustion concept where fuel and combustion air are kept separate by means of an oxygen carrier, and the CO2 capture is inherently achieved. LÄS MER
