Question

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:

CH O CO H O
CH O HCHO H O
4 2 2 2
4 2 2
+ → +
+ → +

The feed to the reactor contains equimolar amounts of methane and oxygen. Assume a basis of 100
moles/hr. Calculate the molar composition of the reactor output stream and the selectivity of
formaldehyde production relative to carbon dioxide production. The fractional conversion of methane
is 0.90 and the fractional yield of formaldehyde is 0.855.

2. Methane and oxygen react in the presence of a catalyst to form formaldehyde. In a parallel reaction,
