Chemical-Looping Combustion (CLC) of biofuels is a promising technology for cost-efficient CO2 separation and can lead to negative emissions when combined with carbon capture storage. A potential challenge in developing CLC the effects alkali metal-containing compounds released during fuel conversion. This study investigates interactions between an oxygen carrier (OC), CaMn0.775Ti0.125Mg0.1O3-?...

As global power generation is currently relying on fossil fuel-based plants, more anthropogenic CO2 being released into the atmosphere. During transition period to alternative energy sources, carbon capture and storage seems be a promising solution. Chemical-looping combustion (CLC) an conversion technology designed for of fuel with advantageous capabilities. In this work, 1D computational flui...

The formation of NOx from fuel-bound nitrogen is important for the design chemical-looping combustion (CLC) power plants. This work studied to what extent NO and NH3 reacts with perovskite-like oxygen carrier ilmenite under conditions relevant CLC. Based on mass balance calculations, N2 was major outlet N-species in all experiments. More measured at lower temperatures a higher oxidation level c...
