The blast furnace
Reactions in which oxygen is removed are called reduction reactions. In this reaction, the iron(III) oxide is reduced to iron, and the carbon is oxidised to carbon dioxide.
How does iron react with CO2 in a blast furnace?
In the upper region of the blast furnace where temperature range from 600 to 700 C. the iron ore or iron oxide is reacts with the gaseous CO reductant to produce iron: Fe 2O 3(s) + 3CO(g) → 2Fe + 3CO 2(g) Lower in the blast furnace where higher temperatures occur, the iron ore may react directly with the coke or carbon:
What is formed in a blast furnace?
In a blast furnace a mixture of iron oxide (Fe2O3), coke (carbon derived from coal), and limestone are heated to produce elemental iron (Fe) plus residual slag.
Why does the temperature of a blast furnace increase with temperature?
This reaction is responsible for increasing the temperature of the blast furnace so that the other reactions between the carbon compounds and iron oxide can take place. It is essential to increase the temperature of the furnace to levels near 700 degree Celsius for iron oxide to react and form iron.
What is iron extraction blast furnace metallurgy?
Iron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron.
