Title:
REGENERATED DENITRATION CATALYST AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2021121423
Kind Code:
A
Abstract:
To provide a regenerated denitration catalyst in which, by using a used denitration catalyst, denitration performance is restored as compared to the denitration catalyst before use, and to provide a method for producing the same.SOLUTION: A regenerated denitration catalyst according to the present disclosure is a mixture in which a denitration catalyst containing a first titanium oxide as a main component and used in denitration reaction that decomposes nitrogen oxide in gas into nitrogen and water using a reducing agent, and a second titanium oxide having a larger specific surface area per unit weight than the first titanium oxide are existing together. The content ratio of the second titanium oxide to the total weight of the first titanium oxide and the second titanium oxide preferably is 10 wt.% or more and 90 wt.% or less.SELECTED DRAWING: Figure 7
