  2. 1. Chemical-Looping Combustion with Solid Fuels

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

    Abstract : 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. READ MORE

  4. 2. The Influence of Dopants on the Growth of Diamond by CVD

    Author : Tanguy Van Regemorter; Karin Larsson; Matthias Schreck; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diamond; growth; chemical vapour deposition; nitrogen; phosphorus; boron; sulphur; density functional theory; Materials chemistry; Materialkemi;

    Abstract : Diamond is an important material in many industrial applications (e.g., machining of hard materials, bio-electronics, optics, electronics, etc.) because of its exceptional properties such as hardness, tolerance to aggressive environments, compatibility with human tissues, and high carrier mobility.

  5. 3. Hydrogen, an Energy Carrier of the Future

    Author : Christian Hulteberg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Catalysts; Aerosols; Gasification; Hydrogen; Systems; Kemiteknik och kemisk teknologi;

    Abstract : The climate is changing, something that many scientists correlate to increased emissions of greenhouse gases. The effluent that is considered to have the highest impact on global warming is carbon dioxide, when effect and quantity are taken into account. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Manganese Materials in Solid Fuel Chemical Looping Combustion

    Author : Matthias Schmitz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon capture; CLOU; manganese ores; chemical-looping;

    Abstract : Against the background of rising anthropogenic greenhouse gas emissions, carbon capture andstorage (CCS) has been proposed as a means of mitigating climate change by storing CO2 capturedfrom large point sources in underground geological formations such as aquifers or depleted oilandgas fields. While first generation CCS technologies rely on active gas separation with anassociated energy penalty, chemical looping combustion (CLC) can avoid that step by utilizingsolid metal oxide particles to transfer oxygen from combustion air to fuel, making CO2 captureinherent to the process.
