ABSTRACT:
A method of regeneration of a SCR catalyst for use in high temperature thermal processes such as in a power plant facility burning fossil fuels, bio-based fuels, or a combination thereof, wherein the catalyst is poisoned by phosphorous components in the flue gas and the catalyst is treated using a base, preferably an alkali metal hydroxide.
