Abstract

In this work, NiFe2O4 was prepared as oxygen carrier (OC) and its redox performance with lignite was systematically studied by thermogravimetric analyzer (TGA) experiments. Surface structures of the fresh and reduced NiFe2O4 were characterized by SEM, BET, and XRD methods. In comparison with NiO and Fe2O3, the presence of Ni in the NiFe2O4 complex increases the specific surface and pore volume, enhancing its reactivity and oxygen transfer capacity during lignite CLC. Further, multi-cycles experiments confirmed the stability of high reactivity of NiFe2O4.
