Akademika Lavrent'eva 5, 630090, Novosibirsk, Russia aut Selective exothermic catalytic reactions in a reverse heat front [Elektronische Daten] [A. Zagoruiko] A model system of exothermic reactions of selective and complete catalytic conversion is considered. The system comprises the reactions A + m[B] ⇒ C + [], C + n[B] ⇒ D + [], and B + [] ⇒ [B], where A and B are the initial reactants, C is the desired product (of the selective conversion), D is the undesired side product (of the complete conversion), [B] is the reactant B chemisorbed on the catalyst surface, and [ ] is a free catalytic active site. Numerical study of the system of reactions in an adiabatic catalyst bed shows that the yield of the desired product and the specific performance of the catalyst can be significantly increased if the reactions are performed not under steady-state conditions but in unsteady-state modes involving periodic time-separated introduction of the reactants A and B. Of greatest interest is to carry out the process in a reverse heat front propagating upward the flow of the gaseous reaction mixture, since, in this front, the maximal catalyst temperature is much lower and also the conversion selectivity is high.
