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 thebalance noncombustible ash is fed to a reactor with astoichiometric amount of CO2. The coke is fed at 77�F, and the CO2enters at 400�F. Heat is transferred to the reactor in the amountof 5859 Btu/lbm coke fed, the gaseous products and the solidreactor effluent (the ash and unburned carbon) leave the reactor at1830�F. The heat capacity of the solid is 0.24 Btu/(lbm?�F). (a)Calculate the percentage conversion of the carbon in the coke. (b)The carbon monoxide produced in this manner can be used as a fuelfor residential home heating as can the coke. Speculate on theadvantages and disadvantages of using the gas.
