Methane (CH4) and oxygen (O2) react to form formaldehyde (CH2O) (reaction #1), with a competing side reaction (#2) in which methane and oxygen form carbon dioxide (CO2): CH4(v) + O2(g) -> CH2O(v) + H2O(l) (reaction #1) CH4(v) + 2O2(g) -> CO2(g) + 2H2O(l) (reaction #2) A fresh feed of an equimolar gas mixture of CH4 and O2 is combined with a recycle stream and fed to a reactor. The single-pass conversion of CH4 is 30% and the selectivity of CH2O...
