Production of formaldehyde (CHO) in a continuous reactor involves the catalytic oxidation of methanol (CHOH): CHOH + 1/2O ---> CHO + HO The reaction is accompanied by a side reaction where some of the product reacts with oxygen to produce CO and HO: CHO + 1/2O ---> CO + HO The feed to the reactor contains methanol and 50 kmol/hr of oxygen gas. Suppose the reactor is designed to yield 70% conversion of methanol and the product leaving the reactor is expected to have the selectivity of 6 kmol CHO/kmol CO. For the production of 900 kg/hr of formaldehyde, determine the amount of methanol required (kg/hr) and the molar composition (%) of outlet gas in dry basis.
