Bifurcation and chaos for a mutating autocatalator in a CSTR

In this paper, we develop a conceptual model for autocatalytic reactions in which the autocatalyst undergoes a mutation process in a completely stirre d tank reactor. Three cases with different mutation coefficient, a, and mut ation efficiency, beta, have been considered. The analysis of these cases s hows the importance of the two parameters and the complexity of the resulti ng bifurcation diagrams. Go-existence of a mushroom and an isola have been determined for the first case. The isola portion is a low main product yiel d solution and is to be avoided. A sub-region of 7 co-existing steady state s, with three stable static branches, has been determined for the second ca se. Chaos developing through period doubling and type 1 intermittency has b een shown to occur for a fourth case.
