  1. 1. Development and Characterisation of Oxygen-Carrier Materials for Chemical-Looping Combustion

    Författare :Paul In-Young Cho; Chalmers tekniska högskola; []
    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

  3. 2. Properties of oxygen carriers based on natural and waste materials at high degrees of reduction

    Författare :Victor Purnomo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high reduction; defluidization; chemical-looping gasification; oxygen carrier; reactivity;

    Sammanfattning : Oxygen carriers play an important role in multiple energy conversion processes, such as chemical-looping technology and oxygen-carrier-aided combustion. This thesis particularly explores how a high reduction degree of an oxygen carrier can affect its performance. LÄS MER

  4. 3. Using affordable materials from metallurgical industries in Oxygen Carrier Aided Combustion and Chemical-Looping Combustion

    Författare :Felicia Eliasson Störner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen carriers; Ash interactions; Potassium interactions; Chemical-Looping Combustion; Oxygen Carrier Aided Combustion;

    Sammanfattning : Oxygen carriers are solid oxides of transition metals that can be used to convert fuel in the absence of gaseous oxygen in a process called Chemical-Looping Combustion (CLC). The use of oxygen carriers makes it possible to produce undiluted CO2 without expensive gas separation. LÄS MER

  7. 5. 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
