摘要
介绍了失效活性Pd/C催化剂经制粒焙烧、浓盐酸浸出、二氯二氨络亚钯沉淀精炼法提纯、水合联胺还原制取海绵Pd粉的工艺。钯回收率≥ 95 %,纯度≥ 99.95 %。
The technology of producing sponge Pd was produced.That was pelletizing and roasting the ineffective and active Pd catalyst,leaching it by concentrate hydrochloric acid,precipitation-purificating by Pd(NH 3) 2Cl 2,and reducing by hydration combined amine.Pd recovery ≥95%,purity ≥99.95%?
