Special case of no catalyst inflow

If the reactor is fed by an inflow of pure A, so fi0 = 0, matters are especially simple. The stationary-state condition is given by 

The condition for tangency is independent of Kc in this system, requiring 

Multiple intersections occur at long residence times, when the flow line L has a low gradient, and require 

This latter result compares with the condition tres i, appropriate to the irreversible case. 

Two other real solutions exist if eqn (6.33) is satisfied, given by the roots of a quadratic

Figures 6.19(a-d) show the four different types of bifurcation diagram where the stationary-state extent of reaction is plotted as a function of residence time for the model with the uncatalysed reaction included for the special case of no catalyst inflow, 0Q = 0. Three patterns have been seen before (a) unique, (b) isola, and (c) mushroom, in the absence of the un-...
