The exothermic reaction of stillbene (A) to form the economically important trospophene (B) and methane (C), i.e.,
A ⎯⎯→ B +C
was carried out adiabatically and the following data recorded:
The entering molar flow rate of A was 300 mol/min.
(a)What are the PFR and CSTR volumes necessary to achieve 40% conversion? (VPFR=72 dm3,VCSTR=24 dm3)
(b)Over what range of conversions would the CSTR and PFR reactor volumes be identical?
(c)What is the maximum conversion that can be achieved in a 105-dm3
CSTR?
(d)What conversion can be achieved if a 72-dm3PFR is followed in series by a 24-dm3CSTR?
(e)What conversion can be achieved if a 24-dm3CSTR is followed in a series by a 72-dm3PFR?
(f)Plot the conversion and rate of reaction as a function of PFR reactor volume up to a volume of100dm3.
