摘要：
In the present work, the reduction kinetics of iron molybdate (Fe2MoO4) by hydrogen gas was investigated by thermogravimetric analyses (TGA). Both isothermal and nonisothermal experiments were conducted. By using fine particles, very shallow powder bed, and high hydrogen flow rate, the study could be focused on the chemical reaction. The activation energy obtained from the isothermal experiments was found to be 173.5 kj/mol, which was in reasonable agreement with the value of 158.3 kj/mol obtained from the nonisothermal experiments. The reduction product was found to be an intermetallic compound, Fe2Mo, of microcrystalline structure.
