Dynamics of a cascade of two continuous stirred tank polymerization reactors with a binary initiator mixture

摘要: The dynamic behavior of two continuous stirred tank reactors in series has been investigated for free radical solution polymerization styrene with a binary mixture initiators having different thermal decomposition activities. For wide range initiator feed composition, both exhibit quite complex nonlinear steady state and transient behavior. When the reactor residence time is used as bifurcation parameter, second can have up to five states. certain operating conditions, bifurcations various types periodic solutions observed, such Hopf bifurcation, isolas, period doubling, period-doubling cascade, homoclinics. effects other variables, total concentration, coolant temperature, volume ratio on dynamics, are illustrated show two-reactor system catalyzed by t-butyl perbenzoate benzoyl peroxide.
