Sažetak
Canadian hematite acid pellet with low magnetite and olivine contents were isothermally reduced by hydrogen and carbon monoxide at 600 to 1 000 °C. Pellet reduction was investigated by a thermo gravimetric analysis measuring oxygen weight loss as a function of time. Then macroscopic and microscopic examinations, X-ray and carbon analyses were also used to elucidate the mechanisms of pellet reduction. Activation energy is around 27 kJ/mol for H2 atmospheres and is about 15 kJ/mol for the mixture of H2 and CO. Carbon producing from CO disproportionation reaction performs a catalyzer at the final reduction of pellet.
