  • Process for the preparation of supported nickel catalysts
    Patent number: 4317748
    Abstract: Highly effective supported nickel catalysts having finely divided metallic nickel deposited thereon and high specific metal surface areas are obtained by a process wherein a support material is contacted with a nickel soap in an inert hydrocarbon and the resulting nickel-bearing support subsequently subjected to a sulfiding step followed by reductive treatment. The present catalyst compositions are useful as hydrogenation catalysts, particularly for the hydrogenation of fatty materials.
