Performance of Industrial Residues as Low Cost Oxygen Carriers
Paper i proceeding, 2017

In Chemical-looping combustion (CLC) an oxygen carrier is circulating, and transporting oxygen, between an air and fuel reactor, thus separating the flue gas stream from the nitrogen in the air. Except for the oxygen carrier all parts of a CLC system are conventional fluidized bed technology. Here, four iron-based industrial residues, and the conventional oxygen carrier ilmenite, are examined as oxygen carrier. The results indicate that two of the material, exhibit a better performance than ilmenite. This opens the possibility of not using virgin material as oxygen carrier and offers a new possible use for industrial residue material.
