Abstract
Catalyst which has become deactivated during a hydrocarbon synthesis (HCS) process is reactivated - rejuvenated using an external reactivation - rejuvenation vessel resulting in a multiple HCS reaction - catalyst rejuvenation reactor vessel design. Flow of the catalyst is synthesis product slurry from the reactor vessel to the rejuvenation vessel and the flow of rejuvenated catalyst back to the reactor vessel are driven by gravity only.
