A Revolution in NOx Control Several Versions of One

UltraCat Catalytic lter tubes have nanobits of SCR catalyst embedded in the lter walls. Operating range is 350°F to 950°F. The large reactive surface area of the micronized catalyst produces high NOx removal at temperatures lower than standard SCR. Good results start at 350°F and improve to 95% removal at 450°F and above.Automotive Selective Catalytic Reduction (SCR) Market co catalyst walls scr catalyst walls2 days ago · Automotive Selective Catalytic Reduction (SCR) Market Regional Analysis, Growth Drivers and Competitive Vendors Continental AG, Faurecia, Friedrich Boysen GmbH & Co.
