Question
One step in making synthetic detergents is preparation of butanal (also called butyraldehyde) from propene (also called propylene), CO, and hydrogen:CH3CH--(double bond)CH2+ CO+ H2<--->CH3CH2CH2CHO
The reaction takes place in a gas-phase reactor at 5 atmosphere pressure. The flow rate of the inlet stream to the reactor is 1200 gmol/h. The reaction is reversible with an equilibrium constant of 8 atm ^-2 at the operating temperature of 180 degrees C.
(a) If the enthalpy of formation of butnol vapor is -204.8 kJ/mol, determine its free energy of formation using the information in the problem statement and the thermodynamic data in the Appendix.
(b) If the inlet stream consists of 20 mol% propene, 40 mol% CO, and 40 mol% H2, determine the fractional conversion of propylene, the butanal production rate, and the percent butanal in the reactor effluent?
