Hydrogenation - Wikipedia

Hydrogenation – meaning, to treat with hydrogen – is a chemical reaction between molecular hydrogen (H 2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum.The process is commonly employed to reduce or saturate organic compounds.Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene.
