Question
Normal butane is to be isomerised to isobutane in a PFR. For this example, the reaction is elementary and not reversible. The “new” specific reaction rate constant of 10 h-1 was re-measured at 380 K after an employees 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.
Find initial reaction rate.
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
