从废TDI氢化触媒中回收金属钯

Process Research of Recovering Metal Palladium from Waste TDI Hydrogenation Catalyst

阐述了从废TDI氢化触媒中回收贵金属钯的工艺方法。通过对废触媒中钯的焚烧富集、除杂、精制等工艺步骤,使钯的回收率达到98%以上,产品纯度达到国家标准要求(HPd-2,Pd%≥99.95%)。

The paper described the process method of recovering the metal palladium from waste TDI hydrogenation catalyst. By burning and accumulating, impurity cleaning purifying, the recovering rate of palladium is up to 98%, the product purity reached the national standardQdPd-2,Pd%≥99. 95%）.
