Formaldehyde is produced by catalytic oxidation of methanol by the following reaction: CH3OH + 1/2 O2 CH2O + H2O. Unfortunately, formaldehyde also reacts with oxygen by the following reaction: CH2O + 1/2O2 CO + H2O. Assume that methanol and twice the stoichiometric amount of air (assume 79mol% N2, 21mol% O2) needed for complete conversion of the methanol to the desired products (formaldehyde and water) are fed to the reactor. Assume there is 90% conversion of methanol and there is 75% yield of formaldehyde based on the theoretical production of formaldehyde by the first (desired) reaction. Determine the composition of the product gas leaving the reactor.
