A gas consisting only of CO and N2 is made by passing a mixture of flue gas and air through a bed of incandescent coke (assume pure carbon). The two reactions that occur both go to completion: CO2 + C-2CO AH,,298 172.46 kJ/mol AH,298-221.05 kJ/mol AH. 2C+02-200 The flue gas composition is 12.8 mol % CO, 3.7 mol % CO2, 5.4 mol % O2, and 78.1 mol % N₂. The flue gas/air mixture is so proportioned that the heats of the two reactions cancel. If the feed stream is preheated to 875 °C, and the temperature of the coke bed is therefore constant at 875 °C. If the process is adiabatic, what ratio of moles of flue gas to moles of air is required. Pulto Mixer Coke Flue gas Air

Question
A gas consisting only of CO and N2 is made by passing a mixture of flue gas and air through a bed of incandescent coke (assume pure carbon). The two reactions that occur both go to completion: CO2 + C-2CO h AH,,298 172.46 kJ/mol - 221.05 kJ/mol -- ΔΗ,,298 The flue gas composition is 12.8 mol% CO, 3.7 mol % CO2, 5.4 mol % O2, and 78.1 mol % N₂. The flue gas/air mixture is so proportioned that the heats of the two reactions cancel. If the feed stream is preheated to 875 °C, and the temperature of the coke bed is therefore constant at 875 °C. If the process is adiabatic, what ratio of moles of flue gas to moles of air is required. 2C+02 → 2CO - = AH. Pl Mixer Coke Flue gas Air
