2) Methane and oxygen react in the presence of a catalyst to form formaldehyde. In a parallel reaction methane is oxidized to carbon dioxide and water: CH4 + O2 HCHO + H20 CHạ + 2 02 CO2 + 2 H20 The feed to the reactor contains 15.3% CH4, 17.8% O2 and 66.9% N2 by mol. Molar flow rate of feed to the catalytic reactor is 300 mol/s. The fractional conversion of methane is 0.9 and the fractional yield of formaldehyde is 0.8. a. Draw and label a flowchart. b. Calculate the molar composition (by mole %) of the reactor output stream and selectivity of formaldehyde relative to carbon dioxide by using the extent of reaction method.
