Elements of Chemical Reaction Engineering, 6th Edition Figure P2-10c Levenspiel plot for an adiabatic exothermic hetero- geneous reaction. 1. Assuming that you have a fluidized CSTR and a PBR containing equal weights of catalyst, how should they be arranged for this adia- batic reaction? Use the smallest amount of catalyst weight to achieve 80% conversion of A. 2. What is the catalyst weight necessary to achieve 80% conversion in a fluidized CSTR? (Ans: W = 23.2 kg of catalyst) 3. What fluidized CSTR weight is necessary to achieve 40% conversion? 4. What PBR weight is necessary to achieve 80% conversion? 5. What PBR weight is necessary to achieve 40% conversion? 6. Plot the rate of reaction and conversion as a function of PBR cata- lyst weight, W. Additional information: FAO = 2 mol/s. 257 Fluidized catalyst pellets
