Question
Incomplete Combustion of Methane
Methane is burned with air in a continuous steady-state combustion reactor to yield a mixture of
carbon monoxide, carbon dioxide, and water. The reactions taking place are
CH, +02 - CO + 2H,O
(1)
CH4 + 202
CO2 + 2H2O
(2)
The feed to the reactor contains 7,80 mole% CH4, 19.4% O2, and 72.8% N2. The percentage con-
version of methane is 90.0%, and the gas leaving the reactor contains 8 mol CO,/mol CO. Carry out
a degree-of-freedom analysis on the process. Then calculate the molar composition of the product
stream using molecular species balances, atomic species balances, and extents of reaction.
