  • Combination sulphur adsorbent and hydrogenation catalyst for edible oils
    Patent number: 6391815
    Abstract: An improved catalyst for edible oil hydrogenation produced by the incorporation of a sulphur adsorbing zeolite with a supported nickel hydrogenation catalyst. The zeolite is a cation-exchanged form of low silica faujasite with a silica to alumina ratio from about 1.8 to 2.1. The hydrogenation catalyst is a supported nickel catalyst. The zeolite is incorporated into the stabilization media with the reduced hydrogenation catalyst to form a physical blend of sulphur adsorbing zeolite and reduced nickel hydrogenation catalyst in a stabilization medium.
