16. Copper in Chemical-Looping Combustion (CLC) and Chemical-Looping with Oxygen Uncoupling (CLOU)
Sammanfattning : The chemical-looping combustion (CLC) and chemical-looping with oxygen uncoupling (CLOU) processes are attractive solutions for efficient combustion with inherent separation of carbon dioxide. These processes use a metal oxide as an oxygen carrier to transfer oxygen from an air to a fuel reactor where the fuel, or gasification products of the fuel, reacts with the oxygen carrier. LÄS MER
17. The chemical nature of CO2 adsorption in zeolite A
Sammanfattning : The climate changes are accelerated by increasing levels of carbon dioxide in the atmosphere connected to the fossil-fuel-based energy system. Substantial reforms of the system are needed immediately and could include the implementation of carbon capture and storage (CCS) technologies. LÄS MER
18. Selection of oxygen carriers for chemical-looping combustion using methane as a fuel
Sammanfattning : 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. LÄS MER
19. Sustainable porous organic materials : Synthesis, sorption properties and characterization
Sammanfattning : The resources available to us humans, including metals, minerals, biomass, air, water, and anything else on the planet, are being used at an increasing rate. This anthropogenic use of resources both depletes the resources and has negative impacts on other resources, e.g. the biosphere. LÄS MER
20. Partial carbon capture – an opportunity to decarbonize primary steelmaking
Sammanfattning : Climate change requires that all energy-related sectors drastically reduce their greenhouse gas emissions (GHG). To have a high likelihood of limiting global warming to 1.5°C, large-scale mitigation of GHG has to start being implemented and cause emissions to fall well before Year 2030. LÄS MER
