Abstract

$SrCo_{0.8}Fe_{0.1}Nb_{0.1}O_{3-{\delta}}$ oxide was synthesized by solid state reaction method. Dense ceramic membrane was prepared using as-prepared powder by pressing and sintering at $1250^{\circ}C$. XRD result of membrane showed single perovskite structure. The oxygen permeability were measured under 0.21 atm of oxygen partial pressure ($P_{O_2}$) and between 800 and $950^{\circ}C$. The oxygen permeation flux of $SrCo_{0.8}Fe_{0.1}Nb_{0.1}O_{3-{\delta}}$ membrane was increased with the increasing temperature. The maximum oxygen permeation flux was $1.839mL/min{\cdot}cm^2$ at $950^{\circ}C$. Long period permeability experiment was carried out to confirm the phase stability and $CO_2$-tolerance of membrane containing Nb in the condition of air with $CO_2$ (500 ppm) as feed stream at $900^{\circ}C$. The phase stability and $CO_2$-tolerance of $SrCo_{0.8}Fe_{0.1}Nb_{0.1}O_{3-{\delta}}$ were investigated by XRD and TG analysis. The result of $SrCo_{0.8}Fe_{0.1}Nb_{0.1}O_{3-{\delta}}$ which exposed carbon dioxide for 100 hours indicated 8wt% of $SrCO_3$. But it was known that the level of $SrCO_3$ production dose not have a significant effect on oxygen permeability.

고상반응법을 이용하여 $SrCo_{0.8}Fe_{0.1}Nb_{0.1}O_{3-{\delta}}$ 조성의 산화물을 합성하였으며, 합성된 분말은 압축 성형 후 $1250^{\circ}C$에서 소결하여 치밀한 세라믹 분리막을 제조하였다. XRD 분석을 통해 단일상의 페롭스카이트 구조를 확인하였다. 산소 분압이 0.21 atm, 측정 온도가 $800{\sim}950^{\circ}C$인 조건하에서 산소투과를 분석한 결과 온도가 증가할수록 산소투과량은 증가하였고, $950^{\circ}C$에서 $1.839mL/min{\cdot}cm^2$로 최대값을 나타내었다. 니오븀(Nb)을 포함한 세라믹 분리막의 상안정성 및 이산화탄소 내성을 확인하기 위하여 $900^{\circ}C$에서 이산화탄소가 500 ppm이 포함된 혼합공기를 이용하여 장기투과 실험을 수행하였다. 이산화탄소에 노출된 $SrCo_{0.8}Fe_{0.1}Nb_{0.1}O_{3-{\delta}}$의 상안정성은 XRD와 TG로 분석하였다. 분석 결과, 이산화탄소에 노출된 $SrCo_{0.8}Fe_{0.1}Nb_{0.1}O_{3-{\delta}}$ 조성의 경우 약 8%의 $SrCO_3$가 생성되었으나, 이 수준의 $SrCO_3$ 생성량은 분리막의 산소투과도에 큰 영향을 주지 않는 것을 확인하였다.
