Abstract:
A process for rejuvenating reversibly deactivated catalyst particles in a three phase hydrocarbon synthesis slurry comprising said particles and gas bubbles containing H.sub.2 and CO in a hydrocarbon slurry liquid into which a mixture of CO and H.sub.2 is flowing, said process comprising reducing the CO content of said mixture entering the slurry to less than 10 mol %, the H.sub.2 /CO being greater than 3/1 followed by passing a CO free purge gas and H.sub.2 through said slurry to remove said CO and form a CO reduced slurry and then passing an H.sub.2 containing catalyst rejuvenating gas through said CO reduced slurry to at least partially rejuvenate said catalyst particles and form a rejuvenated catalyst slurry and rejuvenating offgas.
