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。
Pd alloy can capture Pt in the ammoxidation reaction.The efficiency of capturing Pt by PdNialloy gauze and double-effect platinum gauze(DEC)was compared in a nitric acid plant and the capturingmechanism was analyzed.The results show that Pt consumption of the DEC gauze is26%lower than thatof the PdNi alloy gauze.Maintaining stable operation of the plant system,improving ammonia airpurification and timely replacing the catalyst will lower the platinum consumption.
