Abstract

Catalysts comprising a suspension in oil of finely-divided nickel, such as those prepared according to Specification 478,386 are reactivated by treatment with dry or super-heated steam followed by reduction with hydrogen or other reducing gas. The temperature of reactivation may be that at which the catalyst was originally produced, e.g. 230 DEG C. Specification 370,252, [Group IV], also is referred to.
