GENERAL-ANALYSIS OF THE DYNAMICS OF PROCESSES OCCURRING IN A POROUS CATALYST PELLET

Based on two methods, namely the method proposed by the present author s [8-10], [16-20] and using the software package AUTO 97 [21] a proced ure has been derived for developing extended bifurcation diagrams for processes in a porous catalyst pellet. These diagrams include informat ion about regions of parameters with stable and statically unstable st eady states as well as about regions of bifurcation to oscillatory sol utions bounded by the Hopf bifurcation points. They also indicate the amplitude of oscillations together with their stability. They provide a wealth of information on the dynamics of processes occurring in cata lyst pellets; such information is crucial in analysing the operation o f chemical reactors.
