Abstract

The kinetics of Fe ₂O ₃→FeO reduction by syngas of selected compositions (N ₂/CO/H ₂) in T = 700-900 °C was investigated. Hancock-Sharp method, based on Johnson-Mehl-Avrami-Erofeev's equation was applied. Both surface-boundary-controlled reaction and surface nucleation mechanisms control the kinetics at the initial stage of the process. The reaction's rate increases with T and H ₂ content. The activation energies for selected syngas compositions were elaborated. Artificial Neural Network was applied for alternative process modeling in the same parameters' range.
