Abstract: The present invention relates to a SCR catalytic article, comprising —a substrate and —a copper-containing small pore zeolite, having a crystal structure characterized by a decrease of unit cell volume upon sulfurization and desulfurization of less than Å3 as determined by an X-ray powder diffraction, wherein the sulfurization and desulfurization are carried out in accordance with the processes as described in the specification, and to an exhaust treatment system comprising the same. The present invention also relates to a method for determining whether a metal-promoted small pore zeolite is resistant to irreversible sulfur poisoning and a method for evaluating whether a metal-promoted small pore zeolite is qualified for resistance to irreversible sulfur poisoning.
