Methane is autoreformed adiabatically with oxygen and steam. The methane and the oxygen are fed at 25C. The steam is fed at 233C. The exit gas contains CO, CO2, and hydrogen. The temperature is 600C and the ratio of H2O vap/O2 fed is equal to 2. Determine the amount of water and oxygen required to perform the autorefoming of methane and the composition of the product gas.
