Abstract:
The present invention relates to a method for regenerating a catalyst that can effectively remove a poison bound to a catalyst without chemical injury while minimizing the loss of catalytically active components through a process with improved efficiency, whereby the regenerated catalyst may exhibit excellent denitrification performance.

Claim (Index 1):
A method for regenerating a catalyst, comprising:\n spraying steam to a spent catalyst; and spraying dry ice particles to the spent catalyst, wherein the surface temperature of the spent catalyst is 25\u00b0 C. to 50\u00b0 C., wherein the temperature of the steam is 100\u00b0 C. to 500\u00b0 C., wherein the amount of the sprayed steam is 300 cc/min to 1200 cc/min, wherein in the spraying of steam to the spent catalyst, a liquid material is dispersed on the surface of the spent catalyst, wherein in the spraying of dry ice particles to the spent catalyst, the liquid material dispersed on the surface of the spent catalyst is frozen, and the dry ice particles are ground, wherein the spent catalyst comprises a selective catalytic reduction (SCR) catalyst.
