1. Screening of oxygen-carrier particles based on iron-, manganese-, copper- and nickel oxides for use in chemical-looping technologies
Abstract : 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.

2. Key Aspects of Sintering Powder Metallurgy Steel Prealloyed with Chromium and Manganese
Abstract : The powder metallurgy (PM) process is a cost efficient near net-shape technology suitable for sustainable manufacturing of structural steel components. A drawback with the PM technology is the difficulty to use oxidation sensitive alloying elements, such as Cr and Mn. READ MORE

3. Catalytic Incineration of CO and VOC Emissions over Supported Metal Oxide Catalysts
Abstract : Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. READ MORE

4. Manganese Combined Oxides as Oxygen Carriers for Chemical-Looping Combustion
Abstract : The global emissions of greenhouse gases are increasing and the development of mitigation measures is becoming more important. One of the alternatives proposed is carbon capture and storage, where the carbon dioxide emitted from large point sources is captured, compressed and stored in underground storage sites. READ MORE

5. Selection of oxygen carriers for chemical-looping combustion using methane as a fuel
Abstract : In order to meet new demands on clean energy producing technologies, chemical-looping combustion could play an important role. With this technique, CO2 from the flue gases can be separated and collected without excessive energy and efficiency penalty. This is because nitrogen from the combustion air is never mixed with the fuel. READ MORE
