Abstract (English):
For standard functional elements of catalytic converters the original methodology of a heterogeneous catalysis is proved. The model assumes complex use of micro (nano) and macro physical and chemical representations of chemical kinetics. Wide temperature and concentration ranges of work of automobile catalytic converters allowed to assume probability of course of process on four limit mechanisms. The critical phenomenon allocates diffusion in a time of an active layer.
