Abstract

Zeolites demonstrating better SCR of NO_x 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 NO_x 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 NO_x 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.
