1. Oxygen Carriers Materials for Chemical-Looping Technologies
Abstract : Carbon dioxide is the gas which contributes most to the greenhouse effect. It is released in large quantities from fossil fuel-based power plants around the world. It is generally accepted that a rapid decrease in the emissions of carbon dioxide is needed. READ MORE

2. Chemical Transformation of Inorganic Species in Thermochemical Conversion of Waste-Derived Fuels - The Role of Oxygen Carriers
Abstract : Waste-derived fuels are used increasingly in heat and power production systems in Sweden. Thermal conversion of waste-derived and biomass fuels offers the possibility of achieving carbon dioxide-neutral or even negative emissions. To limit global warming, it is essential to integrate these systems with carbon capture and storage. READ MORE

3. Fate of Trace Elements in Thermochemical Conversion of Waste Fuels Using Oxygen Carriers
Abstract : The metals zinc, copper and lead are amongst the more abundant trace elements in waste fuels. The fate of these elements is important to study because they can affect the thermochemical conversion process and end up in ashes. READ MORE

4. Manganese ores as oxygen carriers for chemical-looping combustion
Abstract : Chemical looping combustion (CLC) is a fluidized bed system that circulates metal oxide particles in order to transport oxygen from an air reactor to a fuel reactor. In the fuel reactor a fuel reduces the oxygen carrier while producing CO2 and H2O. The oxygen carrier is then transported back to the air reactor and reoxidized. READ MORE

5. Behavior of iron-based oxygen carriers at deep reduction states
Abstract : 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. READ MORE
