Diesel engine emissions have attracted more and more attention around the world. Regulations around the world implement stricter controls on NOx (nitrogen oxide) emissions from diesel-engined vehicles. Stricter emission standards have driven the demand for active filtration systems that incorporate NOx reduction technology; SCR catalysts provide temperature stability and operating temperature flexibility to remove NOx to meet strict global emission regulations.
The SCR catalysts are made of various porous ceramic materials as the substrate, the honeycomb SCR catalyst can effectively reduce NOx emission.
