One can view the blast furnace from a simple viewpoint as a process in which the principal reaction is:


Fe2O3 + C → Fe + CO

But some other undesirable side reactions occur, mainly,

Fe2O3 + C → FeO + CO

After mixing 600 lb of carbon (coke) with 1.00 ton of pure iron oxide, Fe2O3, the process produces 1200 lb of pure iron, 183 lb of FeO and 85 lb of Fe2O3. Calculate the following items:

a) The percentage excess carbon furnished, based on the principal reaction.
b) The percentage conversion of Fe2O3 to Fe.
c) The pounds of carbon used up and the pounds of CO produced per ton of Fe2O3 charged.
d) What is the selectivity in this process (of Fe with respect to FeO)?
