Аннотация доклада:
Silver-alumina catalysts are one of the most promising catalysts for selective reduction of NOx by hydrocarbons in lean-burn and diesel exhausts. Ag/Al2O3 catalyst effectively removes NOx at 300‑450oC. However, for practical use the temperature “window” of the effective catalyst operation is needed to be extended toward lower reaction temperature (Treact <250-300o). In this study an attempt has been made to improve performance of Ag/Al2O3 catalyst by its combination with Pt/Al2O3 catalyst, which is known to be active within 200-280oC temperature range.
