Enhancing properties of iron and manganese ores as oxygen carriers for chemical looping processes by dry impregnation [PDF]

, 2015
The use of naturally occurring ores as oxygen carriers in CLC processes is attractive because of their relative abundance and low cost. Unfortunately, they typically exhibit lower reactivity and lack the mechanical robustness required, when compared to ...
