Normal heptane is dehydrocyclicized to toluene and hydrogen in a continuous vapor-phase
reaction:
C7H16 → C6H5CH3 + 4 H2
Pure heptane at 400°C is fed to the reactor at a rate of 100 mol/s. The reactor operates
isothermally at 400°C and the reaction goes to completion. Data: The average heat capacity of nheptane between 25°C and 400°C is 0.2427 kJ/(mol°C). Calculate the required heat transfer to or
from the reactor in kJ/s. What is the heat of the heptane dehydrocyclization reaction at 400°C and
1 atm?
