PBR Derivation

General Balance on W





Steady State



Differentiate with respect to W and rearrange

Rearranging and integrating between
   W = 0, F_A = F_A0
   W = W₁, F_A = F_A1
We obtain

Multiplying by -1 and switching the limits of integration

The equation gives the catalyst weight necessary to reduce the entering flow rate from F_A0 to F_A1 by chemical reaction.
