FE-NI COMPOUND OXIDE FOR CHEMICAL LOOPING COMBUSTION PROCESS AND METHOD OF MANUFACTURING THE SAME

摘要

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.
