11. Capture of CO2 from solid fuels using Chemical-Looping Combustion and Chemical-Looping Oxygen Uncoupling
Sammanfattning : In order to meet the global demand of CO2 neutral energy, chemical-looping combustion could play an important role. Oxygen can be transferred from the combustion air to the fuel by means of oxygen carrying metal oxide particles circulating between two reactors, an air- and a fuel reactor. LÄS MER
12. Behavior of iron-based oxygen carriers at deep reduction states
Sammanfattning : Oxygen carriers have an important role as bed materials in both common circulating fluidized bed combustion unit (also known as oxygen-carrier-aided combustion, OCAC) and in various chemical looping processes. Contrary to conventional bed materials, e.g., sand, oxygen carriers are capable of transferring both oxygen and heat. LÄS MER
13. Screening of oxygen-carrier particles based on iron-, manganese-, copper- and nickel oxides for use in chemical-looping technologies
Sammanfattning : Capture and storage of carbon dioxide from combustion will likely be used in the future as a method of reducing emissions of greenhouse gases and thus be part of the overall strategy to stabilize the atmospheric levels of CO2. Chemical-looping combustion is a method of combustion where CO2 is inherently separated from the non-condensable components in the flue gas without the need for an energy intensive air separation unit.

14. Chemical-Looping Combustion with Natural Gas Using NiO-Based Oxygen Carriers
Sammanfattning : CO2 capture and storage has been proposed as an alternative to mitigate global warming. Chemical-looping combustion 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
15. Investigation of Nickel- and Iron-Based Oxygen Carriers for Chemical-Looping Combustion
Sammanfattning : Carbon capture and storage has the potential of reducing emissions of CO2, generated by combustion of fossil fuels. Chemical-looping combustion is a method intended to capture CO2 without an energy consuming gas separation process. LÄS MER
