| 中文摘要: |
| 钯合金可在氨氧化反应中捕集铂，对某硝酸厂使用PdNi合金网和双功效铂催化剂(DEC)功能网捕集铂的效果进行了对比，并对捕集机理进行了分析。结果表明，DEC功能网比PdNi合金网的铂耗低26%，保持机组稳定运行、做好氨空气净化、及时更换催化剂等措施有利于降低铂耗。 |
| 英文摘要: |
| 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. |
