Abstract

RECOVERY of precious metals from SPENT CATALYSTs is justified due to mainly environmental regulations, COncerns of sustained development and economic added value. In this work RECOVERY of MOlybdenum and CObalt from spent REFINERY catalysts are studied. Various methods of RECOVERY of these metals from SPENT CATALYSTs have been reviewed and COmpared. Experimental methods have been used to find the practical methods and optimum COnditions for RECOVERY. It has been found that one can recover about 93% of the initial CO by solving the catalyst in boiling water and about 97% of the initial MO by leaching with NaCl and 85% by leaching with Na2CO3 solution in presence of H2 O2 of spent Hydrotreating catalyst.
