Reduction of Iron Ores by Naphtha

Kinetics of Reduction of Iron Oxides and Ores by Carbon

ITIHEORETICAL considerations and experimental findings point out that reduction of iron oxides and I ores by carbon proceed via the gas' phase, whenever the latter is present. The overall reaction is a coupling of the following two component reactions, viz., Gasification of carbon C(S) CO2 (g) = 2C0 (g) and Reduction of iron oxide mFe.0y(S) -fCO (g) = nFezOw [S) CO2 (g) ' Recent kinetic studies...

Characterization of Properties and Reduction Behavior of Iron Ores for Application in Sponge Ironmaking

Determination of Relationship between Autoignition of Sponge Iron and Specification of the Iron Ores

Sponge iron (DRI) due to the high surface area, often shows a high tendency to re-oxidation and at some cases spontaneous combustion (autoignition). In this work, re-oxidation behavior and autoignition of sponge iron, produced from different types of iron ore has been investigated. Isothermal and non-isothermal re-oxidation experiments were carried out on each type of DRI and their autoignition...
