Cyclopentadiene decomposes when heated at 255F according to the following reaction, Cyclopentadiene 1/2 Dicyclopentadiene
The reaction proceeds with an activation energy of about 29500 Btu/lbmol.
If the reactor pressure and pressure drop are 400 and 15 psia respectively:
A. Determine the product stream temperature and volume required to carry out the reaction in a CSTR at 50 % conversion in adiabatic mode of operation.
B. Determine the optimum reactor volume and the corresponding temperature if the reaction is carried out in an adiabatic mode with conversions raging from 50 to 90 % in CSTR.(change the conversion with an interval of 5 % i.e 50, 55, 60, 65, 70, 75, 80, 85 and 90).
C. Predict the volume of reactor for the same reaction by replacing CSTR with PER. Select a suitable reactor for the above mentioned reaction conditions and state the reasons for the selection.
D. Draw the profile of pressure drop, temperature, total flow and mole fraction of Cyclopentadiene and mole fraction of dicylopentadine (as function of reactor configuration) if the reaction is carried out in PFR for the conversions of 55 % and 60 %. (Note: Specify the desired temperature points if any, while simulating the PFR).
E. Simulate the reaction by stoichometric reactor model and determine the heat of reaction in BTU/Ibmole and other physical properties of the product stream .
The rate of reaction is reported as I / Vr dn /dt =kI (Cyclopentadiene )2
Where: kI= k0 exp( -E/RT)
k0 = 4.729(1010) ft/IIbmoI/ h
