Abstract
A method for regenerating a denitration catalyst for exhaust gases discharged from coal-burning apparatus, in which a used catalyst whose denitration performance has lowered is contacted with fluidized abrasive particles. As a result, catalyst poisons deposited on the catalyst surface are removed by abrasive contact.
Claims5
A method for regenerating a denitration catalyst for exhaust gases from a coal-burning apparatus which comprises arranging in a closed system a grating on which catalyst pack is disposed, putting abrasive particles inside said grating, feeding air so as to fluidize said abrasive particles in said closed system and then contacting the catalyst, whose denitration performance has lowered, with said fluidized abrasive particles to remove poisons deposited on the surface on the catalyst to regenerate the catalyst.
