Development of Cu-based oxygen carriers for Chemical-Looping with Oxygen Uncoupling (CLOU) process

► Several Cu-based oxygen carriers for CLOU process were developed. ► The reaction rates for oxygen generation and regeneration were determined in a TGA. ► Agglomeration and attrition phenomena was determined in batch fluidized-bed tests. ► Materials with 60 wt.% CuO on MgAl2O4 or 40 wt.% CuO on ZrO2 were found to be adequate.
