Description
Hydrogenation is a chemical unit process, in which hydrogen (H2) and an element or a compound in the presence of a catalyst. Hydrogenation generally has the following two types: hydrogenation of unsaturated bonds and removal of certain protective groups (also known as hydrogenolysis). Almost all unsaturated groups can be directly hydrogenated into saturated groups in a highly stable organic compound. Hydrogenation reactions are not only applied in the organic synthesis in the laboratory, but also it has important applications in the fields of petrochemicals, energy, food and pharmaceuticals.
