Abstract:
Embodiments of the invention relate to processes and apparatus for the washing and recovery of metal-containing catalyst solids in a form suitable for reclamation. More specifically, a catalyst recovery process comprises removing an organic residue with a washing medium from a metal-containing catalyst solids, recovering washed solids, and treating the washed solids under oxidative conditions to form non-reactive solids. The treatment oxidative conditions may be effective to convert the metal(s) into an oxide form and/or may facilitate the removal of remaining organic residue from the washed solids. The treatment of the washed solids may comprise calcination. In some embodiments, the metal-containing catalyst solids may be recovered from a slurry stream, and the process further comprises passing the slurry stream though a separation unit to obtain a catalyst-enriched retentate slurry. In some embodiments, the organic residue comprises a hydrocarbon wax, and the solid catalyst is a hydrocarbon synthesis particulate catalyst.
