摘要： 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.

摘要： This invention relates to methods and apparatus for separating liquid products and catalyst particles from a slurry used in a Fischer-Tropsch reactor system. The preferred embodiments of the present invention are characterized by a separation system that uses a sedimentation chamber, which contains at least one inclined channel that enhances the settling of particles within the slurry. The enhanced settling separates the slurry into a catalyst-rich bottom stream and a catalyst-lean overhead stream. The catalyst-rich bottom product stream is preferably recycled to the reactor, while the catalyst-lean overhead stream can be further processed by a secondary separation system to produce valuable synthetic fuels. The inclined channel may be provided by a structure selected from the group consisting of tube, pipe, conduit, sheets, trays, walls, plates, and combinations thereof.
