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 ...

Process modelling and techno-economic analysis of natural gas combined cycle integrated with calcium looping [PDF]
, 2016 Calcium looping (CaL) is promising for large-scale CO2 capture in the power generation and industrial sectors due to the cheap sorbent used and the relatively low energy penalties achieved with this process. Because of the high operating temperatures the
