Coke can be converted into CO (a fuel gas) in the reaction:
CO2(g) + C(s) → 2 CO(g)
A coke that contains 84% carbon by mass and the balance noncombustible ash is fed to a reactor with a stoichiometric amount of CO2. The coke is fed at 77°F, and the CO2 enters at 400°F. Heat is transferred to the reactor in the amount of 5 859 Btu/Ibm coke fed. The gaseous products and the solid reactor effluent (the ash and unburned carbon) leave the reactor at 1830°F. The heat capacity of the solid is 0.24 Btu/(lbm·°F).
5.1.1 Calculate the percentage conversion of the carbon in the coke. (15)
5.1.2 The CO produced can be used as a fuel for residential home heating, as can the coke. Speculate on the advantages and disadvantages of using the gas. (5)
