Chemical Looping Combustion of Sulphurous Solid Fuels using Spray-Dried Calcium Manganate Particles as Oxygen Carrier
Paper in proceeding, 2014

A perovskite material, CaMn0.9Mg0.1O3-δ, has been investigated as oxygen carrier in a 10 kW chemical looping pilot using sulphurous fuels. Operation with inert gas in the fuel reactor showed that the material released significant amounts of gas-phase oxygen, indicating CLOU properties. Stable operation with fuel was performed during 29 hours with performance superior to previously tested oxygen carriers like ilmenite. A slight deterioration of the conversion was detected during the experiments, which can be attributed to the accumulation of sulphur in the oxygen carrier. However, a regeneration test with non-sulphurous fuel showed that this process is reversible and that the oxygen carrier can be regenerated after being subjected to sulphurous fuels.
