General Principles And Processes of Isolation Of Elements
Carbon monoxide is more effective agent that carbon below 983 K but above this temperature the reverse is true. How would you explain this?
In the production of iron from its oxide ore, the mixture of ore, coke and limestone is heated with a blast of air in furnace. Below 983K oxides of iron are reduced by carbon monoxide to iron.
Fe2O3 +CO → 2FeO +CO2
FeO +CO → Fe + CO2
Above 983K, Fe2O3 undergoes reduction by hot coke to iron. This region is called fusion zone
Fe2O3 +3C → 2Fe +3CO +Heat
Thus carbon monoxide is more effective agent than carbon below 983K.
