The feed to a plug flow reactor contains equimolar amounts of methane and oxygen. Assume a basis of 100 mol feed/s. The fractional conver- sion of methane is 0.9, and the fraction yield of formaldehyde is 0.855. Calculate the molar composition of the reactor output stream and the selectivity of formaldehyde production relative to carbon dioxide pro- duction. Methane (CH,) and oxygen react in the presence of a catalyst to form formaldehyde (HCHO). In a parallel reaction, methane is oxidized to carbon dioxide and water: CH, +O2 → HCHO + H;O CH, + 20, → CO, + 2H-O Find: Calculate the molar composition of the reactor output stream and the selectivity of formaldehyde production relative to carbon dioxide production.

Reactive Processes

Reactive processes are the processes in which any reaction occurs. The reactions can be any combination reaction, decomposition reaction, combustion reaction, oxidation reaction, reduction reaction, neutralization reaction, displacement reaction, or double displacement reaction.
