MODELING COMPLEX HETEROGENEOUS CATALYTIC PROCESSES USING NON-LANGMUIR APPROACH

Complex heterogeneous catalytic reactions have been considered that proceed via strongly chemisorbed species (SCS): methanol, pyrocathechol, and diphenylamine syntheses, as well as hydrocarbon aromatization. Under typical conditions of these processes, the composition of a surface layer is determined rather by adsorption substitution reactions (ASR) than conventional Langmuir steps. Modeling the processes should, therefore, comprise both ASR and chemical transformation reactions of SCS. This approach provides the completely adequate kinetic description which can be used to control and optimize overall processes above.
