ABSTRACT:
A cobalt catalyst for use in the Fischer Tropsch reaction of synthesis gas to form hydrocarbons is activated or regenerated by treatment of a cobalt containing catalyst with a gas containing carbon monoxide, said gas containing less than 30% v hydrogen. The catalyst obtained has increased activity and greater selectivity towards producing C.sub.5+ hydrocarbons.
