GENERAL KNOWLEDGE

Detailed explanation-1: -Hence, the catalyst used in the hydrogenation of oils is nickel.

Detailed explanation-2: -Hydrogenation. Raney nickel is a heterogeneous hydrogenation catalyst. It promotes the reaction of hydrogen with organic compounds (compounds that contain carbon), and, like all catalysts, is not consumed in the process.

Detailed explanation-3: -Metallic nickel is known to efficiently catalyze hydrogenation reactions, but one of its major drawbacks lies in its lack of selectivity, linked to side-reactions of hydrogenolysis and over-hydrogenation. More selective hydrogenations can be obtained upon the introduction of a second metal in combination with Ni.
