Abstract(Eng)
Reduction reactivity of new oxygen carriers for chemical looping combustion system were investigated using CH4 as a reduction gas in a bubbling fluidized bed reactor and compared with that of former SDN70 oxygen carrier. New oxygen carriers showed good reduction reactivity at different CH4 concentration. N018-R2 particle represented better reactivity than SDN70 at high CH4 concentration. N018-R2 particle showed higher fuel conversion and CO2 selectivity than those of SDN70 particle within the temperature range of 750-900℃. Moreover, attrition loss of N018-R2 particle was almost same with that of SDN70 particle. Consequently, we could select N018-R2 particle as the best oxygen carrier.
