| 摘要 |
The invention relates to a process of recovering nickel, on an Al2O3 carrier, from spent catalysts by pyrometallurgical formation of NiO, the process comprising calcinating the nickel catalysts with a mixture of NaOH and Na2 CO 3 in a ratio : NaOH/catalysts/Na 2 CO 3 of 1/1/04, at a temperature of 750 900 degrees C, and solubilizing the sodium aluminate formed by calcination and recovering the aluminium from the obtained solution by a known process |
