A blast furnace is the main unit in the production of iron from iron ore. One can view the blast furnace as a process in which the principal desired reaction is:
Fe2O3 + 3 C ? 2 Fe + 3 CO
In addition, an undesired reaction occurs:
Fe2O3 + C ? 2 FeO + CO
After mixing 600 lb of carbon (coke) with 1.00 ton of pure iron oxide, Fe2O3, the process produces 1200.0 lb of pure iron, 183 lb of FeO, and 85.0 lb of Fe2O3.
Calculate the following:
(A) The percentage excess carbon supplied, based on the principal reaction.
(B) The percentage conversion of Fe2O3 and the percentage yield of Fe.
(C) The pounds of carbon used up and the pounds of CO produced per ton of Fe2O3 supplied.
(D) The percentage selectivity of Fe2O3 for Fe.
