The work concerns the spectral, entropy and bifurcation analysis of thedynamics of a reverse-flow system. The existence of chaotic oscillations wasdemonstrated in a wide range of changes in the parameters of the model. Themodel of such a system can be compared to a periodically stimulated pendulum.The periodic apparatus here is a tubular reactor, which can generate its ownoscillations. Reverse flow is cyclical stimulation. As a result, both of thesedevices can start to oscillate chaotically, and they actually do. The purposeof using reverse flow is to increase the conversion degree. This is becauseafter reverse, the cold stream of raw material falls into the heated reactorinlet.
