  • Nickel/silica catalyst for hydrotreating unsaturated organic compounds
    Patent number: 5616531
    Abstract: A nickel/silica catalyst having a Ni/SiO.sub.2 molar ratio of 10 to 2.5, preferably 6 to 3, contains zinc in an amount of at least 500 ppm (based on the nickel) and maximally in a molar ratio Zn/SiO.sub.2 of 1. Additionally, the catalyst may comprise Mg in a molar ratio Mg/Ni of 0.05-0.15, max. (Mg+Zn)/Sio.sub.2 molar ratio is 1. Also the catalyst may comprise Al in a molar ratio Al/Si of 0.05-0.5. Also methods of preparing the catalyst and its use for hydrogenating oils and fats have been described.
