| Description
| - A CSTR model of heterogeneous catalytic oxidation of CO and C2H2 exhibits various types of dynamical behaviour (multiple steady states, oscillatory behaviour). These phenomena are caused by a complex interaction of multiple reaction and adsorption steps, not by the usual thermokinetic effect. Recently, a detailed kinetic reaction scheme including over 20 reaction steps has been proposed for catalytic CO oxidation, NOX reduction and hydrocarbons oxidation taking place in a three-way catalytic converter (TWC). TWC is the most common reactor for detoxification of automobile exhaust gases. This reactor is typically operated with periodic variation of inlet oxygen concentration. For a lumped model, we report results of the stoichiometric network analysis of CO and C2H2 oxidation using a detailed kinetic reaction scheme of TWC. The reaction subnetworks determine feedback loops, which cause the oscillations within certain regions of parameters in bifurcation diagrams constructed by numerical conti

- Dynamické chování katalytické oxidace CO a uhlovodíků v katalytickém konvertoru se může modelovat průtočným ideálně promíchávaným reaktorem. Model vykazuje složité dynamické chování. Tyto nelineární jevy nemohou být vysvětleny termokinetickým efektem, jelikož teplota je konstantní, a proto musí být způsobeny vztahy mezi reakčními a adsorpčními kroky. Pro model se soustředěnými parametry a konstantní koncentrací kyslíku na vstupu uvedeme výsledky analýzy stechiometrických sítí. Výsledky analýzy zahrnují podsítě se smyčkami se zpětnými vazbami, jež způsobují oscilace v definovaných oblastech parametrů v bifurkačním diagramu. (cs)
