distribution of sulfur was studied during chemical looping combustion of anthracite based Fe2O3/Al2O3 oxygen carrier(OC). Reduction temperature and content of Fe2O3 were tested as variables. The work showed that the carbonaceous gas quantity increased with increasing temperature
while it increased first and then decreased with content of Fe2O3 improved. The proportion of CO2 reached the highest value 37.6% at 850℃ and there were no SO2 detected at experiments. At 2 h
the occupation of sulfur in OC increased with improvement of both temperature and the content of Fe2O3. At 5.5 h
the occupation of sulfur in OC decreased obviously with improvement of temperature. Surface microstructure of reacted OC was also evaluated using a scanning electron microscope. The results showed that OC sintered gradually with increase of content of Fe2O3.
