Title:

METHOD FOR REGENERATING SPENT DENITRIFICATION CATALYST

Document Type and Number:

Japanese Patent JP2004298760

Kind Code:

A

Abstract:

To provide a method for regenerating a spent denitrification catalyst, by which the spent denitrification catalyst can be regenerated without deteriorating the denitrifying activity by only decreasing the sulfur dioxide oxidizing activity.

This method for regenerating the spent denitrification catalyst containing titanium oxide comprises a step of depositing at least one of molybdenum trioxide and molybdate on the spent denitrification catalyst, a step of drying the molybdenum trioxide/molybdate-deposited catalyst and a step of firing the dried catalyst at 400-700°C.
