| Description
| - Před několika lety byl navržen detailní reakční mechanismus, zahrnující více než 20 reakcí pro popis současné oxidace CO a uhlovodíků a redukce NOX , třícestného katalytického konvertoru (TWC), nejčastěji používaného pro detoxikaci výfukových plynů automobilové dopravy. TWC je provozován s periodickou změnou koncentrace kyslíku na vstupu. TWC můžeme v nejjednodušším případě popsat modelem se soustředěnými parametry, jež vykazuje složité dynamické chování. Analýza stechiometrických sítí poskytnula informace o reakční podsíti CO oxidace a identifikovala zpětnovazebné smyčky způsobujících oscilační chování v jistých oblastech parametrů. Model s periodickou změnou vstupní koncentrace kyslíku dokazuje přechod od oscilačního chování k chaosu cestou zdvojením periody. Dále jsou vypočteny závislosti rotačního čísla na amplitudě a periodě změny na vstupu. Numerické simulace distribuovaného modelu TWC poskytují vícenásobné periodické a aperiodické oscilace. Časoprostorové profily vysvětlují složitost reakčně-t (cs)
- Early experimental observations of chaotic behavior arising via the period-doubling route for the CO catalytic oxidation both on Pt (110) and Pt/ γ-Al2O3 porous catalyst were reported more than 15 years ago. Recently, a detailed kinetic reaction scheme including over 20 reaction steps was proposed for the catalytic CO oxidation, NOX reduction, and hydrocarbon oxidation taking place in a three-way catalyst (TWC) converter, the most common reactor for detoxification of automobile exhaust gases. This reactor is typically operated with periodic variation of inlet oxygen concentration. For an unforced lumped model, we report results of the stoichiometric network analysis of a CO reaction subnetwork determining feedback loops, which cause the oscillations within certain regions of parameters in bifurcation diagrams constructed by numerical continuation techniques. For a forced system, numerical simulations of the CO oxidation reveal the existence of a perioddoubling route to chaos. The dependence o
