Abstract

A process is disclosed for regenerating a catalyst (60) used in a process for synthesizing hydrocarbons (40). The synthesis process involves contacting a feed stream (10) comprising hydrogen and carbon monoxide with a catalyst (50) in a reaction zone (30) maintained at conversion-promoting conditions effective to produce an effluent stream comprising hydrocarbons (40). The regeneration process involves contacting a deactivated Fischer-Tropsch catalyst (60) with a regeneration gas (70) under regeneration-promoting conditions that include a pressure lower than the mean Fischer-Tropsch reaction pressure, for a period of time sufficient to reactivate the Fischer-Tropsch catalyst (60).
