Аннотация:It has been found that the activity of both zeolite (Fe-Beta) and oxide (V2O5–WO3/Al2O3) catalysts in the process of 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 NOx conversion occurs due to NOx reduction via “fast” SCR pathway, whereas for the zeolite catalyst the NO2-SCR pathway also makes a significant contribution.
