Document Type and Number:
WIPO Patent Application WO/2004/000461
Kind Code:
A1
Abstract:
A method of regenerating a NOx removal catalyst, which enables easily restoring the catalytic activity of deteriorated NOx removal catalyst, and which can be performed easily and ensures a high operating efficiency. In particular, a method of regenerating NOx removal catalyst (14) of an exhaust gas denitrizer, comprising immersing the catalyst in ordinary-temperature regeneration water (31) substantially not containing chlorine and cleaning components, taking out the same and effecting dewatering thereof.
