Question
For the liquid phase reaction system, A+B →D rı = kı CA CB AH:(200 °C) = -200 kJ/mol A+B →U 2= k2 Ca² CB AH,(200 °C) = -150 kJ/mol Eal =100 kJ/mol and Ea2 = 50 kJ/mol, where Eal and E2 are the activation energies for ki and k2, respectively. Both reactions can be considered irreversible and heats of both reactions are constant. Starting with A and B in equal concentrations and a conversion of 70% is required for A. Explain and justify your answer. 1) selectivity to D? The reactor will be operated isothermally at 200 °C and pressure drop is negligible. What reactor (CSTR or PFR) would you choose to maximize the total 2) With an inlet temperature of 200 °C, if we need to design a CSTR, should the reactor be operated adiabatically or isothermally to maximize the total selectivity to D?
