Wustite micropellets (Feo0.941O) were isothermally reduced at 900-1100°C with H2, CO and their mixtures. The effect of reducing gas composition and the total gas pressure on the rate of reduction was investigated. The kinetics and mechanisms of reduction deduced from the microscopic examination, surface area measurements and carbon analysis were found to depend mainly on the reducing gas composition. The highest rate of reduction was obtained in H2 while the slowest was in CO. The reduction with H2-CO mixtures was not additive.
