Transcribed Image Text:
The irreversible first-order (wrt partial pressure of A) gas-phase reaction: A → B is carried out isothermally in a "fluidized" catalytic CSTR containing 50 kg of catalyst. Currently, 50% conversion is realized for pure A entering at a pressure of 20 atm. There is virtually no pressure drop in the CSTR. It is proposed to put a PBR containing the same catalyst weight in series with the CSTR. The pressure drop parameter for the PBR: α = 0.018 kg-¹ The particle size is 0.2 mm, the bed porosity is 40%, and the viscosity is the same as that of air at 200°C. Fluidized catalyst pallats -TA dm³-s mol X a. What is the best arrangement of the reactors, PBR first or last? b. What is the conversion exiting the last reactor? c. What is the pressure at the exit of the packed bed?
