Abstract

It has been found that the activity of the zeolite (Fe-Beta) and oxide (V₂O₅–WO₃/Al₂O₃) catalysts in the selective catalytic reduction (SCR) of NO by NH₃ can be significantly improved in the temperature range of 100–250°C by introducing ozone into the gas stream entering the catalyst. The study of the temperature dependences of the reaction product composition shows that for the oxide catalyst the increase in NO_x conversion occurs due to NO_x reduction via “fast” SCR pathway, whereas for the zeolite catalyst the NO₂-SCR pathway also makes a significant contribution.

期刊介绍： Kinetics and Catalysis Russian is a periodical that publishes theoretical and experimental works on homogeneous and heterogeneous kinetics and catalysis. Other topics include the mechanism and kinetics of noncatalytic processes in gaseous, liquid, and solid phases, quantum chemical calculations in kinetics and catalysis, methods of studying catalytic processes and catalysts, the chemistry of catalysts and adsorbent surfaces, the structure and physicochemical properties of catalysts, preparation and poisoning of catalysts, macrokinetics, and computer simulations in catalysis. The journal also publishes review articles on contemporary problems in kinetics and catalysis. The journal welcomes manuscripts from all countries in the English or Russian language.
