Which of the following facts is/are correct about the blast furnace in Iron metallurgy? Limestone is added to the blast furnace to reduce the iron oxide in the ore to iron. Coke is added to the blast furnace to physically separate iron from other impurities. Carbon dioxide reduces to carbon monoxide.

Which of the following facts is/are correct about the blast furnace in Iron metallurgy? Limestone is added to the blast furnace to reduce the iron oxide in the ore to iron. Coke is added to the blast furnace to physically separate iron from other impurities. Carbon dioxide reduces to carbon monoxide. Correct Answer None

  • None of the given facts are correct.
  • Coke is added to the blast furnace to reduce the iron oxide in the ore to iron because it is a source of carbon monoxide which reduces iron oxide and oxidizes itself to carbon dioxide.
  • Limestone acts as a flux and is added to the blast furnace to physically separate iron from other impurities.
  • Carbon monoxide oxidizes to carbon dioxide.

In the carbonation of a soft drink, the total quantity of carbon dioxide required is the equivalent of 3 volumes of gas to one volume of water at 0⁰C and atmospheric pressure. Calculate (i) the mass fraction and (ii) the mole fraction of the CO2 in the drink, ignoring all components other than CO2 and water. Basis 1 m3 of water = 1000 kg Volume of carbon dioxide added = 3 m3 From the gas equation, pV = nRT 1 x 3 = n x 0.08206 x 273 n = 0.134 mole. Molecular weight of carbon dioxide = 44 And so weight of carbon dioxide added = 0.134 x 44 = 5.9 kg
An iron blast furnace produces hot metal containing 95% Fe. The iron ore charged into the furnace contains 95% Fe2O3 and the rest is gangue. Assume that all the iron in the ore goes to hot metal. The amount of iron ore (in kg) required for producing 1000 kg of hot metal is (Atomic weight of Fe = 56 g mol-1 and that of Fe2O3 = 160 g mol-1)
A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:

500 kg of ore contained a certain amount of steel. After the first blast furnace process, 200 kg of slag containing 12.5% of steel was removed. The percentage of steel in the remaining ore was found to be 20% more than the percentage in the original ore. How many kg of steel were there in the original 500 kg ore?
