Coke can be converted into CO�a fuel gas�in the reaction CO2 (g) + C (s) ?...

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 5859 Btu/lbm 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). (a) Calculate the percentage conversion of the carbon in the coke. (b) The carbon monoxide produced in this manner can be used as a fuel for residential home heating as can the coke. Speculate on the advantages and disadvantages of using the gas.
