Title:
METHOD FOR REGENERATING SPENT DENITRATION CATALYST
Document Type and Number:
Japanese Patent JP2016203066
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for regenerating a spent denitration catalyst inexpensively with a small number of processes while maintaining its shape to a denitration catalyst having higher nitration performance, the catalyst containing titanium oxide as a main component.SOLUTION: In a first embodiment, the method for regenerating a spent denitration catalyst is provided in which the spent denitration catalyst containing titanium oxide as a main component is brought into contact with suspension of particles containing manganese oxide, is drained and is then subjected to drying treatment, thereby the spent denitration catalyst is regenerated. In a second embodiment. the method for regenerating a spent denitration catalyst is provided which is identical to the method in the first embodiment except that a spent denitration catalyst is impregnated with solution containing a compound containing at least one element selected from among vanadium, molybdenum, and tungsten, then is subjected to a drying treatment, thereby the spent denitration catalyst is regenerated.SELECTED DRAWING: None
