Question
Which one of the following reactions occurs during smelting in the reduction zone at lower temperature
(in iron metallurgy) ?
(in iron metallurgy) ?
Options
A.CaO + SiO2 → CaSiO3 (slag)
B.Fe2O3 + 3C → 2Fe + CO
C.3Fe2O3 + CO → 2Fe3O4 + CO2
D.CO2 + C → 2CO
Solution
At lower temperature following reactions occur in blast furnace.
3Fe2O3 + CO → 2Fe3O4 + CO2 ; Fe3O4 + CO → 3Fe + 4CO2 ; Fe2O3 + CO → 2FeO + CO2
3Fe2O3 + CO → 2Fe3O4 + CO2 ; Fe3O4 + CO → 3Fe + 4CO2 ; Fe2O3 + CO → 2FeO + CO2
