2AB follows an elementary rate law and takes place isothermally in a PBR charged with 1.0kg of catalyst. The feed, consisting of pure A,entersthePBRataen pressure of 20atm. The conversion exiting the PBR is 0.3 , and the pressure at the exit of the PBR is 5atm. (a) If the PBR were replaced by a "fluidized" CSTR with 1kg of catalyst, what will be the conversion at the exit of the CSTR? You may assume that there is no pressure drop in the CSTR. (Ans... X=0.4.) (b) What would be the conversion in the PBR if the mass flow rate were decreased by a factor of 4 and particle size were doubled? Assume turbulent flow. (Final exam) (c) Discuss what you learned from this problem as well as the strengths and weaknesses of using this as a final exam
