Abstract
The preoccupation concerning recovering Ni from industrial wastes, represented by used catalysts, is opportune due to their high content of useable metal (30-40%). The paper presents researches concerning recovering Ni as metallic powder from used catalysts Ni/Al2O3. This catalyst, with a 39.44% Ni content, results from caprolactame manufacturing technology by phenol hydrogenation process.
