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.
