| titleOfInvention | Regeneration method of used denitration catalyst |
| abstract | The present invention provides a method for regenerating a used denitration catalyst capable of removing sulfate ions and iron compounds eluted in a cleaning solution and recycling the cleaning solution to greatly reduce waste water. SOLUTION: A method of cleaning a used denitration catalyst with an aqueous oxalic acid solution to regenerate, the step of immersing the used denitration catalyst in an aqueous oxalic acid solution and washing, and adding a calcium salt to the washed oxalic acid aqueous solution. After adjusting to pH = 5-7, the step B of removing the solid content by filtration and the step C of adding succinic acid to the filtrate after the solid content removal and reusing it as a washing solution are repeated.
