Chapter 2, Problem 2.10P
The curve shown in Figure 2-1 is typical of a reaction carried out isothermally, and the curve shown in Figure P2-10B (sec Example 11-3) is typical of a gas-solid catalytic exothermic reaction carried out adiabatically).
Figure P2-10B Levenspiel plot for an adiabatic exothermic heterogeneous reaction.
- (a) Assuming that you have a fluidized CSTR and a PBR containing equal weights of catalyst, how should they be arranged for this adiabatic reaction? Use the smallest amount of catalyst weight to achieve 80% conversion of A.
- (b) What is the catalyst weight necessary to achieve 80% conversion in a fluidized CSTR?
- (c) What fluidized CSTR weight is necessary to achieve 40% conversion?
- (d) What PBR weight is necessary to achieve 80% conversion?
- (e) What PBR weight is necessary to achieve 40% conversion?
- (f) Plot the rate of reaction and conversion as a function of PBR catalyst weight, W.
