Transcribed Image Text:Normal heptane is dehydrocyclicized to toluene and hydrogen in a continuous vapor-phase reaction:
C-H16 → C6H5CH3 + 4 H2
Pure heptane at 495°C is fed to the reactor. The reactor operates isothermally at 495°C and 75.50% of the heptane is
dehydrocyclicized. Data: You may take the average heat capacity ofn-heptane between 25°C and 495°C to be 0.2594 kJ/(mol °C).
