The reactions are usually addition reactions(usually with catalyst Ni) wherein a bond is broken in the compound and another hydrogen is added.

addition of hydrogen to vegetable oil(unsaturated compound) to form vegetable ghee (saturated compound)

a reaction in which hydrogen is added to an unsaturated hydrocarbon in the presence of nickle or palladium as catalyst

Hydrogenation reactions are addition reactions that take place in unsaturated hydrocarbons, wherby water is used to break the double (or triple) bonds and convert them to single bonds, ie, convert unsaturated to saturated hydrocarbons.

Eg

CH₂=CH₂ + H₂O CH₃-CH₂-OH      (Catalyst Phosphoric Acid)

Ethene      Water     Ethanol

Hydrogenation is usually carried out on edible unsaturated hydrocarbons(oils) to convert them into saturated hydrocarbons.
