Abstract The dynamics of a chemical system is thc main characteristic the system. An attracrivc problem pertains to selfoscillation processes. These processes are promising for study regularities tnttetant in Lmemctioa reaction medium wttfi catalytic surface under norrsteady-state conditions operating longer time.
A mathematical model, which simulates the complicated dynamic behavior experimentally observed during CO oxidation over Pd zeolite catalysts is presented. It describes coupling of reaction rate oscillations, generated by various parts inhomogeneous catalytic layer through gas phase. can be shown, that resulting depends upon difference between natural frequencies local oscillators and strength coupling, defined mostly degree conversion. Chaotic could identified under condition weak for with...
Interesting kinetic phenomena, such as multiple steady states and oscillations recently found in the NO+H2 reaction over Rh(533) Rh(111) single crystal surfaces 10−6 mbar pressure range have been studied by means of experiments computer modeling. A mathematical model, consisting five ordinary differential equations taking into account lateral interactions adlayer, has developed for simulating NO+H2/Rh(533) NO+H2/Rh(111) reactions. The simulation results make it possible to explain detail...
A mesoscopic stochastic model of the catalytic reaction 2CO+O2→2CO2 on surface a metal particle is considered. The Markovian chain elementary steps, which mimics oxidation CO nm-sized Pd particle. takes into account effect size rate and role temporal fluctuations concentrations reactants. main goal paper comparison dynamics produced by deterministic obtained via averaging master equation, while catalyst reduced. Intrinsic during are shown to change kinetics drastically for small particles...
