Question
![914. Normal heptane is dehydrocyclicized to toluene and hydrogen in a continuous vapor-phase reaction:
C7H16 CH3CH3 + 4H₂
Pure heptane at 400°C is fed to the reactor. The reactor operates isothermally at 400°C and the
reaction goes to completion. Data: The average heat capacity of n-heptane beween 25°C and 400°C
is 0.2427 kJ/(mol. °C).
(a) Taking a basis of 1 mol of heptane fed, draw and label a flowchart.
(b) Taking elemental species [C(s), H₂(g)] at 25°C as references, prepare and fill in an inlet-outlet
enthalpy table. (See Example 9.5-2.)
Calculate the required heat transfer to or from the reactor (state which it is) in kJ.
(d) What is the heat of the heptane dehydrocyclization reaction (AĤ,) at 400°C and 1 atm?
