  The scope of the paper is the analysis of the possibility of increasing
conversion in different types of systems based on continuous stirred tank
reactors. A numerical model of the cascade with constant direction of material
flow is tested, a model of changes of direction flow and a relaxation model.
The analysis is conducted by means of parametric continuation method and
numerical simulation, with the designation of bifurcation diagrams and time
series. An essential impact of the relaxation method on the increase of the
conversion degree is indicated.
