Question

4. The gasification of coke (the Boudouard Reaction) which takes place in the Ironmaking Blast Furnace in the active coke zone immediately above the tuyeres, can be represented by the following reaction; 2CO gas AG 1900 K-159 000 kJ/kg mole of CO2 CO2, gas + Coke Calculate, using this information: (a) The equilibrium ratio: (Pco)2/Pco2 for the Boudouard reaction at 1900 Kelvin (1627°C) (b) The composition (vol% CO, CO2, N2) of gas rising through the "active" coke zone (1000 K, 2 x 105 Pa total pressure) in an iron blast furnace, assuming C/CO/CO2 equilibrium is attained. (c) The effect of increasing the furnace pressure in the active coke zone by another 10 Pascals
