2. Role of oxygen carriers in different processes
2.1 Chemical Looping Combustion (CLC)
In this process, illustrated in figure 1 , the carbonaceous fuel is burned with oxygen supplied by an oxygen-carrying material, generally a metal oxide (MeO α ). At the outlet of the first reactor (combustion reactor), fumes consisting mainly of carbon dioxide and water vapor are obtained, along with the oxygen carrier in its reduced state (MeO α–1 ). Carbon dioxide can easily be separated from water vapor by condensation for capture. While the oxygen carrier in the reduced state is regenerated in a second reactor (regeneration...
