Title:
METHOD FOR REGENERATING DENITRATION CATALYST
Document Type and Number:
Japanese Patent JP2013180282
Kind Code:
A
Abstract:
To provide a method for regenerating a denitration catalyst, capable of suppressing SO2 oxidation activity of a used denitration catalyst and maintaining high performance of denitration activity.
In a method for regenerating a denitration catalyst, an ammonia catalytic reduction denitration catalyst is regenerated by mixing plaster of 100-400 wt.% with the catalyst to be regenerated. A pasty material obtained by adding the plaster, water and a binder to the catalyst to be regenerated and kneading them is applied to a mesh-like object made of metal or inorganic fiber or is molded into a honeycomb state or a granular state, and thereafter is dried.
