The decomposition of cyclohexane to benzene and hydrogen is mass transfer limited at high temperatures. The reaction is carried out at 2 atm and 500ºC in a plug-flow packed-bed catalytic reactor, 50 cm in internal diameter. The reactor is packed with spherical catalyst pellets that are 1 cm in diameter. The bed porosity is 40%. The feed entering the reactor is 20% cyclohexane and 80% hydrogen at a volumetric flow rate of 60 liters per minute. You may assume that the value of the mass transfer coefficient, kG, is 0.40 cm/min. Calculate the length of reactor necessary to achieve 90% conversion of cyclohexane.
The question belongs to Chemical Engineering and it is about cyclohexane to benzene and hydrogen decomposition. The specifics of the reactor are given along with the catalyst.
