dc.description.abstract
Chemical looping is a promising combustion technology utilizing the cyclic oxidation and reduction of a metal oxide to transport oxygen for a variety of applications related to carbon capture and storage (CCS). The scalable manufacture of a suitable oxygen carrier is a pivotal aspect of this research field. This work surveys the experimental preparation of CuO and CuO/NiO on SiC and SiO2 substrates for chemical looping with oxygen uncoupling (CLOU) applications. A novel impregnation method that enhances the metal-support interaction to increase dispersion and reduce CuO sintering has been developed in this work. Particles prepared using this method, termed "selective adsorption wet coimpregnation", exhibited agglomeration resistance and high reactivity over many regeneration cycles. CuO/NiO@SiO2 oxygen carrier (33 wt % CuO, 1 mol of Ni/99 mol of Cu) showed no signs of agglomeration up to 975 degrees C in fluidized bed testing, cycling between CuO and Cu2O. Thermogravimetric analysis showed no loss in oxygen transport capacity or decrease in kinetics over 100 cycles.
