Hydrogen‐Based Direct Reduction of Iron Oxides Pellets Modeling

The present study deals with the analyses of direct reduction kinetics during hydrogen industrial iron oxide pellets. Various types pellets different percentage total content and metal oxides are examined. They reduced at temperatures pressure (700–1100 °C 1–6 bar) in atmosphere. behavior is described terms time to reduction, rate constant. All obtained results analyzed through employment a commercial multiobjective optimization tool precisely define weight that each single parameter has on behavior. It shown from point view processing conditions, temperature main factor influencing reduction. From properties, it mainly influenced by then porosity basicity index. Also, largely even if governed pores size also percentage, gas pressure, index, porosity.
