- 摘要：
- A process for regenerating a slurry Fischer-Tropsch catalyst (26), which needs regeneration, involves de-waxing and drying the catalyst sufficiently to produce a free-flowing catalyst powder (36) that is fluidizable; fluidizing the catalyst powder; treating the catalyst powder with an oxygen treatment; reducing the catalyst powder with a reducing gas to form a reduced catalyst powder (40); and mixing the reduced catalyst powder with hydrocarbons to form a regenerated, slurry catalyst (44). The oxidation and reduction steps may be repeated. An oxygen treatment includes using a fixed O2 level with ramped temperatures, fixed temperatures with increased O2 levels, or a combination.
