Iron Oxides As Efficient Sorbents For Co2 Capture, Eduin Yesid Mora Mendoza, Armando Sarmiento Santos, Enrique Vera Lopez, Vadym Drozd, Andriy Durygin, Jiuhua Chen, Surendra Saxena
Center for Study of Matter at Extreme Conditions
Carbon dioxide capture/release reactions using magnetite, Fe3O4, and hematite, Fe2O3, as sorbents were studied. Kinetics of mechanically activated chemical reactions between iron oxides and CO2 was investigated as a function of CO2 pressure and planetary ball mill process parameters. It was found that complete carbonation of iron oxides can be accomplished at room temperature and elevated CO2 pressure (10–30 bar). Siderite calcination was studied in vacuum and argon atmospheres. FeCO3 can be decomposed at 367 °C yielding magnetite, carbon and/or iron. This mixture can reversibly re-absorb carbon dioxide in multiple carbonation–calcination cycles. These results suggest that siderite or iron oxides …
