The elementary irreversible gas-phase reaction A B+C is carried out adiabatically in a PFR packed with a catalyst. Pure A enters the reactor at a volumetric flow rate of 20 dm/s at a pressure of 10 atm and a temperature of 450K. (a) Plot the conversion and temperature down the plug-flow reactor until an 80% conversion (if possible) is reached. (The maximum catalyst weight that can be packed into the PFR is 50 kg). Assume that AP = 0. (b) What catalyst weight is necessary to achieve 80% conversion in a CSTR?
