end. TECHNICAL FIELD OF THE INVENTION;Method for producing ammonia nitrogen adsorbent using waste fluidized bed catalytic cracking (FCC) catalyst;I. The technical problem that the invention tries to solve;The waste FCC catalyst, which is a byproduct of the refining company, is in powder form, so its use is limited and therefore it is almost landfilled and disused.;All. The point of the solution of the invention;The present invention is characterized in that a waste FCC catalyst is put into a rotary furnace and heated to oxidize Ni and V to oxidize, carbon is removed by burning, the calcined waste FCC catalyst is pulverized and leached into an acid to neutralize with alkaline, It is intended to be recycled as an ammonia nitrogen adsorbent which is a raw material for treatment.;la. Important Uses of the Invention;Ammonia nitrogen adsorbent
