Fremgangsmåde til regenerering af en denitrifikationskatalysator

Regenerating a denitrating catalyst, comprises introducing denitrification reagent (2) to fumes to be denitrified (1), which have a temperature of 170-280[deg] C, and are sent through the catalyst to be regenerated, raising the temperature in the fumes, to a value of 240-380[deg] C, using at least a burner (401) as the dust content, and continuously measuring downstream of the catalyst, which is not successively passed above and below 20 mg/Nm 3>dry corrected to a reference value of oxygen. An independent claim is included for an installation for the implementation of the process comprising: a reactor (202) containing a catalyst for denitrification; first means (101, 201) to send, to the reactor, the fumes to be denitrified (1) which has a temperature of 170-280[deg] C, preferably 210-280[deg] C, or preferably 220-250[deg] C, and in which a reagent is introduced for denitrification; at least one burner adapted to raise the temperature of the fumes in the first means to a value of 240-380[deg] C, preferably 280-380[deg] C, and second means for measuring the dust content in downstream of the reactor.
