本發明揭露一種應用於化學迴圈燃燒程序中做為載氧體之鎳鐵複合氧化物及其製備方法,其中鎳鐵複合氧化物係單一相的尖晶石結構。製備本發明之鎳鐵複合氧化物的方法包含下列步驟:混合氧化鐵以及氧化鎳以產生混合溶液並以固相球磨法球磨混合溶液;抽乾混合溶液以獲得沉澱物;接著,對沉澱物造粒成型後鍛燒以獲得具單一相之尖晶石結構的鐵鎳複合氧化物。藉由本發明之製備方法所製備出的鐵鎳複合氧化物於化學迴圈燃燒程序中具有良好的氧化率及還原率,並且具有長期持續迴圈以及產氫的能力。 A Fe-Ni compound oxide is used as an oxygen carrier for chemical looping combustion process, wherein the structure of the Fe-Ni compound oxide is a single-phase spinel structure. The method for manufacturing the Fe-Ni compound oxide of the invention includes the following steps: mixing Fe2O3 and NiO to obtain a mixing solution and ball milling the mixing solution by the solid state ball milling method; drying the mixing solution to obtain a precipitate; granulating the precipitate and then calcining the granulated precipitate to obtain the Fe-Ni compound oxide. Accordingly, the Fe-Ni compound oxide manufactured by the method of the invention is provided with high oxidation rate and high reduction rate, and capable of keeping loops and producing hydrogen gas.
