Zeolites demonstrating better SCR of NOx performance due to wide temperature activity, hydrothermal stability and N2 selectivity have been identified under a joint research initiative by the Research Association of Automotive Internal Combustion Engines, Japan. NH3-SCR activity for treating NOx from automotive exhausts was conducted over a wide range of Cu exchanged zeolites with different structures and pore dimensions using various conditions. Results showed tthat the NH3-SCR of NOx activity of the investigated zeolites cannot be limited solely to a single parameter. Also, results shwoed that the involvement of a combined role from two or more of the aforementioned parameters to decide on the SCR activity and selectivity.
