Abstract

Kinetics of iron production via hydrogen-reduction of FeS-CaO mixture during microwave heating was investigated at 750, 570, and 460 °C to clarify the dominant rate-controlling mechanism. Results revealed that the interfacial chemical reaction is rapidly progressed during microwave irradiation and gas diffusion is the dominant rate-controlling mechanism with an activation energy of 22.3 kJ.mol-1. This study demonstrated that the microwave irradiation enhances the rate of chemical reaction during iron production from FeS-CaO mixture.
