Advanced Chemical Reaction Engineering

1. The first-order irreversible liquid-phase reaction 𝐴 → 𝐵 is to be carried out in a jacketed CSTR.
Pure A is fed to the reactor at a rate of 0.5 gmol/min. The heat-generation curve for this
reaction and reactor system,
𝐺(𝑇) =
−∆𝐻𝑅𝑥
𝑜
1 + 1/(𝜏𝑘)
is shown in the Figure below.
(a) To what inlet temperature must the fluid be preheated for the reactor to operate at a high
conversion?
(b) What is the corresponding temperature of the fluid in the CSTR at this inlet temperature?
(c) Suppose that the fluid is now heated 5ºC above the temperature in part (a) and then cooled
10ºC, where it remains; what will be the conversion?
(d) What is the extinction temperature for this reaction system?
