| titleOfInvention | Process to recover valuable metals resource from nickel-cobalt residue of spent hydrodesulfurization (HDS) catalyst |
| abstract | This patent provides an innovative treatment method for recovering nickel (Ni) and cobalt (Co) valuable metals from BS by the 3Hs and solvent extraction purification processes, and more particularly to catalyst materials which have been used in hydrocarbon refining processes, comprising compounds of Co, Ni, molybdenum (Mo) and vanadium (V) on supports which contain aluminum oxide (Al2O3). The innovation concept of the 3Hs process is compared with the conventional mixing acidic leaching method (adding concentrated sulfuric acid agent to hot water), the inverse way (adding drop hot water to concentrated sulfuric acid solution) seems more destroyed and dissolvable for NiAl2O4 and CoAl2O4 the formation of spinel structure effectively spinel structure of BS effectively. This patent aims at describing an optimum operation conditions and a new recovery process of valuable elements present in BS. The influences of BS particle size, solid/liquid ratio (S/L), spontaneous exothermic reaction temperature and additive agents were investigated. The insoluble matter obtained after treatment of the 3Hs process was characterized and elements were recovered by solvent extraction purification techniques. Attention was attracted to the final wastes generated. The BS with H2O2-oxidiation, H2SO4-acidic leaching, Hot H2O-exothermic reaction (the 3Hs process) and solvent extraction hybrid treatment processes allowed good valuable metals recovery. |
