Abstract: A method of regenerating a finely-divided particulate catalyst involves the use of an external regeneration system comprising first and second regeneration stations. The method is particularly adapted to regenerating supported catalysts used in Fischer-Tropsch slurry reactors. A slurry-containing partially spent catalyst is flowed from the reactor and alternately regenerated in one of the first and second regeneration stations. The alternate use of the stations for catalyst regeneration permits one station to receive partially deactivated slurry from the reactor while the other station returns regenerated slurry to the reactor. The operation of the reactor thus may be continuous.
