Abstract

Perovskite oxides are promising oxygen carrier materials to produce O2/CO2 gas for oxyfuel combustion application. In this study, PrBaCo2O5+δ double perovskite oxide was prepared by the EDTA sol-gel method and first applied as oxygen carrier for oxygen production. The oxygen adsorption/desorption performance of PrBaCo2O5+δ perovskite was carrried out in a fixed-bed set-up. The operating factors of oxygen releasing performance were investigated in detail including adsorption temperature, desorption temperature, CO2 volumetric flow rate, and CO2 partial pressure. Due to the kinetic effects of gas-solid reactions, it is found that the adsorption and... (More)

Perovskite oxides are promising oxygen carrier materials to produce O2/CO2 gas for oxyfuel combustion application. In this study, PrBaCo2O5+δ double perovskite oxide was prepared by the EDTA sol-gel method and first applied as oxygen carrier for oxygen production. The oxygen adsorption/desorption performance of PrBaCo2O5+δ perovskite was carrried out in a fixed-bed set-up. The operating factors of oxygen releasing performance were investigated in detail including adsorption temperature, desorption temperature, CO2 volumetric flow rate, and CO2 partial pressure. Due to the kinetic effects of gas-solid reactions, it is found that the adsorption and desorption temperature has greatly influence on the oxygen production performance. The surface morphology was observed by scanning electron microscope (SEM). In addition, the cyclic performance of PrBaCo2O5+δ under the optimal operating condition was examined. The oxygen production amount was reduced slightly from 110.9 mg/g perovskite to 99.2 mg/g after 8 cycles’ test. Therefore, the results indicated that PrBaCo2O5+δ has good stability and reactivity for cyclic use.
