The jet fuel is produced in a PFR at 1.5 atm pressure and 732 K temperature from oligomerization (i.e. a type of polymerization with short polymer chain formation) of butene that is produced from bio-ethanol. The representative reaction equation is 2C4H8 C8H12 + 2H2) gas product. The reaction order conforms to the stoichiometry. In the reaction, butene is mixed with N2 inert (20% butene and 80% N2), and the mixture is fed into the reactor. Assume the pressure drop is negligible, the reaction rate constant (k) is 0.05 L mol-1 s -1 , and the feed flowrate is 60 L min-1 . All the gases obey the ideal gas behavior.

(1) Determine the size (i.e. volume) of the PFR to achieve 50% conversion of butene.

(2) Assume the CSTR reactor is used at the same condition, what is the reactor volume if the same conversion of butene is achieved?
