Abstract
The present invention discloses a preparation method for an activated coke catalyst capable of simultaneously removing NO, SO, and HCl. The method includes: step 1: crushing and sieving activated coke to obtain coke particles with a particle size of 40-60 microns; step 2: putting the activated coke in an oxidizing agent, stirring at 80° C. for 8 h to allow for a thorough mixing and reaction, washing the activated coke obtained after the reaction until a neutral pH is reached, and drying to obtain activated coke with oxygen-containing functional groups; and step 3: impregnating, by equivalent-volume impregnation, the activated coke with oxygen-containing functional groups obtained in step 2 with a copper nitrate trihydrate aqueous solution for 24 h, drying, and putting the activated coke in a resistance furnace, and introducing argon for calcination to obtain the activated coke catalyst capable of simultaneously removing NO, SO, and HCl.
