✦ Synopsis

Extensi®e simulations indicate that in most but not all cases the single-and two-phase models predict similar dynamic beha®ior of a re®erse-flow reactor, when catalyst pellet multiplicity does not occur at any point in the reactor. Differences in the predictions are found in some cases close to the dynamic bifurcation loci of a cooled RFR, or in others when the qualitati®e dynamic beha®ior is ®ery sensiti®e to the ®alue of the parameters, such as close to a transition to chaotic beha®ior. The two models can lead to rather different predictions of the dynamic features when there are large differences between the feed and coolant temperatures.

## Abstract A hybrid system approach is adopted to study the dynamic behavior of a controlled reverse flow reactor, where the occurrence of flow inversions is caused by a feedback control strategy. With this approach it is analyzed, theoretically and numerically a typical behavior of hybrid systems
