More Information
Summary:A selective catalytic reduction (SCR) catalyst article comprising vanadium-free extruded titania substrate comprising a titania-based portion, a filler portion, optionally a zeolitic portion, wherein [a] titania-based portion comprises (i) 1-10wt% Nb, (ii) 5-15wt% Ce, (iii) optionally up to 10wt% W, wherein the balance is at least 60wt% Ti; [b] 1-20wt% filler portion based on the weight of the substrate; [c] optionally up to 20wt% zeolitic portion based on the weight of the substrate. Also disclosed is a method of manufacturing the selective catalytic reduction (SCR) catalyst article.
