摘要
Provided is a method for regenerating a denitration catalyst, a regeneration system for a denitration catalyst, and a cleaning agent for a denitration catalyst, capable of efficiently removing deposits attached to the surface of the catalyst, and also capable of recovering high catalyst performance. The regeneration method includes: a pre-washing step (S12) of washing the denitration catalyst with water; a chemical cleaning step (S14) of immersing the denitration catalyst after washing with water in a chemical solution containing an inorganic acid and a fluorine compound; It includes a step of taking out the denitration catalyst, and a final washing step (S16) of washing the denitration catalyst taken out from the chemical solution with water or sulfamic acid-containing water as a final washing solution.
