  The work concerns the spectral, entropy and bifurcation analysis of the
dynamics of a reverse-flow system. The existence of chaotic oscillations was
demonstrated in a wide range of changes in the parameters of the model. The
model of such a system can be compared to a periodically stimulated pendulum.
The periodic apparatus here is a tubular reactor, which can generate its own
oscillations. Reverse flow is cyclical stimulation. As a result, both of these
devices can start to oscillate chaotically, and they actually do. The purpose
of using reverse flow is to increase the conversion degree. This is because
after reverse, the cold stream of raw material falls into the heated reactor
inlet.
