A reversibly deactivated, particulate catalyst in a hydrocarbon synthesis slurry is rejuvenated by circulating the slurry from a slurry body through a rejuvenation zone in which hydrogen contacts the slurry and rejuvenates the catalyst to form a rejuvenated catalyst slurry and an offgas which contains catalyst deactivating species. The offgas is separated and removed from the rejuvenated slurry before it is passed back into the slurry body. This avoids or minimizes contamination and recontamination of the slurry body with the deactivating species produced by the rejuvenation process.

[ What is claimed is:] [1.] A slurry reactor containing means for rejuvenating a particulate catalyst dispersed in a three phase slurry comprising said catalyst, slurry liquid and gas bubbles, said means comprising a hollow fluid conduit having an entrance and an exit for passing said slurry therethrough the exit being out of the slurry, means for injecting a gas into the interior of said conduit and gas separating means located proximate said conduit exit and in fluid communication with said interior of said conduit, for separating said gas from said slurry liquid exiting said conduit.
