Coke can be converted into CO—a fuel gas—in the reaction CO2(g) + C(s) ? 2CO(g) A coke that contains 84.0% carbon by mass and the balance noncombustible ash is fed to a reactor with a stoichiometric amount of CO2. The coke is fed at 77.0°F, and the CO2 enters at 300.0°F, heat is transferred to the reactor in the amount of 4959 Btu/lbm coke fed. The gaseous products and the solid reactor effluent (the ash and unburned carbon) leave the reactor at 1730°F. The heat capacity of that solid is 0.240 Btu/(lbm °F). Calculate the percentage conversion of the carbon in the coke.
