| 中文摘要: |
| 采用铜捕集法从失效汽车催化剂中回收铂族金属，重点研究了CaO/SiO2质量比、捕集剂、熔炼温度和时间、以及还原剂对Pt、Pd和Rh回收率的影响。结果表明，在CaO/SiO2=1.05，CuO配比35%~40%，还原剂配比6%，熔炼温度1400℃，熔炼时间5 h的条件下，Pt、Pd和Rh回收率分别为98.2%、99.2%和97.6%。 |
| 英文摘要: |
| A copper collection method was used to recover platinum group metals from a spent auto catalysts. The influences of CaO/SiO2 weight ratio, collection agent and reductant on Pt, Pd and Rh recoveries were studied. The recovery rates are 98.2%, 99.2% and 97.6% for Pt, Pd and Rh, respectively, when the collection condition is as follows: 1.05 of CaO/SiO2 weight ratio, 35%~40% of CuO ratio, 6% of reductant ratio, 1400℃ of smelting temperature and 5 h of smelting time. |
