Question: Normal heptane is dehydrocyclicized to toluene and hydrogen in a continuous vapor-phase reaction: C7H16 C6H5CH3 +4 H2 Pure heptanes at 400C is fed to

Normal heptane is dehydrocyclicized to toluene and hydrogen in a continuous vapor-phase reaction: C7H16 → C6H5CH3 +4 H2 Pure heptanes 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-heptanes between 25°C and 400°C is 0.2427 kJ/(mol °C).

(a) Taking a basis of 1 mol of heptanes 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.

(d) What is the heat of the heptanes dehydrocyclization reaction (ΔHг) at 400°C and 1 atm?
