METHOD FOR REGENERATING CATALYST FOR DE-NOX

摘要

A method of generating flue gas denitration waste catalyst is provided to determine cleaning time in the field by analyzing a state of the washing solution as a real time and not analyzing the washing solution in an analytical laboratory where analytical equipment is installed. A method of generating flue gas denitration waste catalyst comprises steps of: (S1) physically removing solid materials precipitated in the flue gas denitration waste catalyst; (S2) removing a poisoning substance precipitated in the flue gas denitration waste catalyst by washing the poisoning substance precipitated in the flue gas denitration waste catalyst by a washing solution for the cleaning time determined through measurement of hydrogen ion concentration; (S3) and drying the flue gas denitration waste catalyst.
