In chemical reactors, an enormous variety of possible regimes, both non-steady-state (transient)and steady-state can be observed. Steady-state reaction rates can be characterized by maxima and hystereses. Non-steady-state kinetic dependences may exhibit many phenomena of complex behavior, such as "fast" and "slow" domains, ignition and extinction, oscillations and chaotic behavior. These phenomena can be even more complex taking into account transport processes in three-dimensional media. In this case, waves and different spatial structures can be generated.
