| Abstract: | Pd alloy can capture Pt in the ammoxidation reaction. The efficiency of capturing Pt by PdNi alloy gauze and double-effect platinum gauze (DEC) was compared in a nitric acid plant and the capturing mechanism was analyzed. The results show that Pt consumption of the DEC gauze is 26% lower than that of the PdNi alloy gauze. Maintaining stable operation of the plant system, improving ammonia air purification and timely replacing the catalyst will lower the platinum consumption. |
