Hydrogenation â to treat with hydrogen â is a chemical reaction between molecular hydrogen (H2) 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. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures.
Hydrogenation is the chemical name for the addition of hydrogen to an existing molecule, usually an organic molecule which has a doubl-bond between two carbon atoms. That bond is broken and a hydrogen atom binds to each of the free bonds on adjacent carbon atoms. H2C=CH2 becomes H3C-CH3.
