Abstract

See full text

Presented is a process for the regeneration of a deactivated nitrogen oxide decomposition catalyst of a selective catalytic reduction system that is a component of a flue gas treating system that is one of parallel flue gas treating systems. The selective catalytic reduction system is isolated to provide a closed system in which a regeneration gas is circulated to regenerate the deactivated nitrogen oxide decomposition catalyst. Denitrified flue gas from a parallel flue gas treating system is introduced and used within the closed system as regeneration gas.
