Normal butane is to be isomerised to isobutane in a PFR. For
this example, the reaction is
elementary and not reversible (ie neglect equilibrium). The “new”
specific reaction rate constant of
10 h-1 was re-measured at 380 K after a students data was found to
be erroneous. The feed for this
reactor will enter at 330 K and will use an existing reactor of
6m3. It will process 200kmol/hr of a
mixture of 40% butane and 60% N2.
a) In Excel plot the conversion X and reactor Temperature along
the reactor assuming adiabatic
conditions
Additional information:
Hrxn = -9000 J/mol butane (ie. Exothermic), Activation energy 50
kJ/mol
Concentration butane0 =15 kmol/m3
CPbutane = 141 J/mol.K,
CPi-butane = 151 J/mol.K, CP N2 =
29.14 J/mol.K
