Dynamics of transition modes in the reaction of steam conversion of СО on Ce_{0.5 - х}Zr_{0.5 -х}La_2хO₂ (х = 0, 0.1) and platinum catalysts on this basis at 650 ^оC is investigated. Numerical modeling of the response curves showed that all the transformations on the support run within the oxidation-reduction mechanism. At the catalyst under the steady conditions, the major contribution into the activity is made by the transformations according to the association mechanism. The dynamics of transient modes is determined by the oxidation-reduction mechanism.
