Abstract
Presented is a process for the off-line regeneration of a deactivated nitrogen oxide decomposition catalyst of a selective catalytic reduction system that is a component of a flue gas treating system. The selective catalytic reduction system is isolated to allow for removal and replacement of deactivated SCR catalyst. The removed SCR catalyst may be regenerated off-line from the flue gas treating system. The off-line regenerated SCR catalyst can be used as a replacement SCR catalyst.
