Abstract

Described herein is a selective catalytic reduction (SCR) catalyst treatment system that includes a vanadium-based SCR catalyst contaminated with a water-soluble contaminant. The SCR catalyst treatment system also includes a water delivery system that is configured to apply water to the vanadium-based SCR catalyst to remove the water-soluble contaminant from the vanadium-based SCR catalyst.
