Abstract

In the present work, magnetite ore fines pellets were prepared for a study of reduction kinetics using hydrogen gas. In the present work, various parameters are investigated to assess their influence on reduction kinetics with respect to hydrogen utilisation. The different input variables influence the process, yielding the reduction fraction. The effect of temperature on reduction kinetics with hydrogen flow rate was explored for the optimum value of these parameters. The temperature is the key variable during the oxygen removal from the iron oxide compound. The breakdown of bonds from ferrous to solid iron molecules is dependent on the temperature of the reacting environment, which decides the rate of reduction. The reduction of magnetite ore occurs in two different segments. In the first phase of reaction, an intermediate phase, Wustite is formed, and then a stable compound is formed. For this study, Indian magnetite ore was chosen as the primary investigation for its chemistry through XRF, EDS and XRD.  Ore fines were crushed to prepare four levels of fineness, such as 100, 200, 300, and 400 mesh, to make pellets for different categories. The study is focused on an alternative solution to conventional coke/coal reduction with pollution-free hydrogen gas as a reductant. A numerical simulation is used to validate the experimental data set, which supports the progressive development with less energy consumption. The reduction temperature range was 700-1000 °C, and hydrogen flow rates were also investigated to assess their impact on reduction kinetics. To investigate the diffusion impact, non-linear curves were also examined for the pore diffusion influence on the reduction mechanism.
