Abstract
A process for producing a partially sulfurized nickel catalyst is disclosed wherein a pre-reduced nickel catalyst comprising nickel having a crystallite size of between about 10 and about 200 A is treated with at least one organic sulfur compound selected from the group consisting of thiophene, alkylthiophenes and mono-, and disulfides and mercaptans, at a temperature of between about 75.degree. and about 200.degree. C at a sufficient hydrogen pressure and for a period of time sufficient to produce a partially sulfurized nickel catalyst containing from about 1.5 to about 8 parts by weight of sulfur per 100 parts by weight of nickel.
