Modeliranje mehanizma oscilatornih katalitičkih procesa, sa primenom na reakciju razlaganja vodonikperoksida

Abstract

Urađena je detaljna analiza postupaka koje bitrebalo primeniti pri analizi svih složenihprocesa, a posebno pri modeliranju oscilatornihkatalitičkih reakcija. Sintezom odabranihmetoda sačinjen je sopstveni opšti postupak koji jeprimenjen na polazni model reakcije Braj-Libhavski. Tokom postupka modeliranja, formiranje niz redukovanih modela i utvrđene su njihoveosobine. Dobijeni uprošćeni modeli i daljeomogućavaju simulaciju oscilacija, a dovoljno supojednostavljeni da omoguće i kvantitativnuanalizu uslova stabilnosti. Primenjenaanalitička procedura daje uvid u ulogu pojedinihdelova reakcionog mehanizma u celokupnomprocesu i naročito u mehanizmu oscilovanja.

Detailed analysis was performed of the methods thatshould be employed in the analysis of complexprocesses, especially in the modeling of the oscillatorycatalytic reactions. By synthesis of selected methods,our own general procedure was made and applied tothe initial model of the Bray – Liebhavsky reaction.During the modeling process, a series of reducedmodels was created and their characteristics defined.The resulting simplified models still allow the simulationof oscillations, but they are sufficiently simplified toallow quantitative analysis of the stability conditions.Applied analytical procedure provides insight into therole of individual components of the reactionmechanism in the whole process and especially in themechanism of oscillations.
