Abstract
Prezenta inventie se refera la un procedeu de recuperare a paladiului din catalizatori de hidrgoenare uzati cu continut mic de paladiu (sub 0,06% Pd) depus pe un suport de alumina solubila în acizi minerali. Recuperarea Pd se realizeaza prin extractie cu solutii ale sarurilor de amoniu în prezenta oxigenului urmata de reducerea paladiului din solutie cu hidrat de hidrazina. negrul de paladiu obtinut este filtrat, spalat si apoi uscat obtinându-se negrul de paladiu pur. procedeul poate fi realizat prin grefarea unei astfel de instalatii la unitatile ce întrebuinteaza catalizatorii de hidrogenare.
