 CH4로 환원된 페라이트를 이용한 CO2 분해 신현창, 정광덕1, 주오심1, 한성환2, 김종원3, 최승철 아주대학교 재료공학과1한국과학기술연구원 나노환경연구센터2한양대학교 화학과3한국에너지기술연구원 수소에너지센터 Decomposition of CO2 with Reduced ferrite by CH4 ABSTRACT The reduced ferrites, reduced NiF $e_2$ $O_4$ and CuF $e_2$ $O_4$, by C $H_4$ were applied to $CO_2$ decomposition to avoid the greenhouse effects. At the reduction reaction above $700^{circ}C$, $H_2$ and CO were generated by partial oxidation of C $H_4$ After the reduction reaction up to 80$0^{circ}C$, the spinel structure ferrites changed to mixture of the oxygen deficient iron oxide (Fe $O_{(1-{delta})}$(0$leq$$delta$$leq$1)) and the metallic Ni or Cu. The rate and quantity of $CO_2$ decomposition with reduced CuF $e_2$ $O_4$ were larger than those with reduced NiFe $O_4$. The $CO_2$ gas was decomposed by oxidation of the oxygen deficient iron oxide. The metallic Cu and Ni were not oxidized and remained in a metallic state up to 80$0^{circ}C$. The $CO_2$ decomposition reaction with the reduced ferrite by C $H_4$ gas is excellent process preparing useful gas such as $H_2$and CO and decomposing $CO_2$ gas. Key words: Reduced ferrite, $CO_2$ decomposition, Partial oxidation
