  4. 2. Investigation of Ilmenite from Oxygen Carrier Aided Combustion: Sulfur Interactions and Recovery of Elements

    Author : Mariane Vigoureux; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Angelica Gyllén; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Carl Johan Linderholm; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

  7. 5. Design and Operation of a Chemical-Looping Reformer for Catalytic Upgrading of Biomass-Derived Gas

    Author : Fredrik Lind; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; Moisture measurements; Biomass combustion; Oxygen carriers; Ilmenite; Catalytic gas cleaning; CFB; Tar cleaning;

    Abstract : AbstractThe removal of tar from the raw gas produced during biomass gasification is necessary before the gas can be used as a feedstock for synthetic fuels. The currently commercially available technologies for gas cleaning, i.e. READ MORE
