Abstract: Досліджено двовимірну математичну модель окиснення монооксиду вуглецю на поверхні платинового каталізатора згідно з механізмом Ленгмюра–Гіншелвуда, яка враховує вплив дифузійних ефектів на перебіг реакційно-дифузійних процесів. Встановлено, що адсорбовані атоми кисню можна вважати нерухомими, а структурні зміни поверхні каталізатора істотно впливають на характер коливного режиму реакції.
A two-dimensional mathematical model for carbon monoxide oxidation on the platinum catalyst surface is investigated according to the Langmuir–Hinshelwood mechanism. This model takes into account the influence of diffusion effects on the course of reaction-diffusion processes. It is established that the diffusion of adsorbed oxygen atoms can be neglected, and the structural changes of the catalyst surface have a significant influence on the character of oscillatory mode of reaction.
