Formaldehyde ( C H 2 O ) can be produced industrially by partial oxidation with air over a silver catalyst. Suppose about 2 3 mol

Formaldehyde (CH2O) can be produced industrially by partial oxidation with air over a silver catalyst. Suppose about 23mol farmeldahyde ts produced per 1mol methanol reacted and that, in addition, some formic acid, H2,CO, and CO2 are produced. In order to ensure high utilization of the reactant, the product gas is scrubbed with H2O to separate the off-gases. The residue Is distilled to produce a pure recycle methanol. Assuming that the reactor inlet gas to the reactor is 35%( mol methanol, calculate the moles of formaldehyre nrodiced ner mot of methanol, given the off-gas composition 20.2%H2,4.8%CO2,0.2%CO,74.5%N2, and 0.3%O2.
