Hydrogenation catalyst used in the production process, but also widely used in the refining process of raw materials and products.
According to the different hydrogenation conditions into three categories:
The selective hydrogenation catalyst, such as petroleum hydrocarbon crackingethylene, propylene as the polymerization material, subject to the selective hydrogenation of alkynes, remove, diene, carbon monoxide, carbon dioxide,oxygen and other impurities, and no loss of alkenes. The catalyst used is generallypalladium, platinum or nickel, cobalt, molybdenum on alumina. Method for manufacturing dosage, catalyst carrier and the control of the active substances,can have different performance of catalyst for selective hydrogenation. Other such as reduction of pyrolysis gasoline hydrogenation of nitrobenzene to aniline,refining, also used in selective hydrogenation catalyst.
Non selective hydrogenation catalyst, the hydrogenation catalyst for saturatedcompounds. Such as nickel catalyst for hydrogenation of benzene to cyclohexanewith Raney nickel catalyst, phenol and hydrogen preparing cyclohexanol, has twonitrile hydrogenation of ethylene diamine with.
The hydrogenation catalyst, such as copper chromite catalyst for thehydrogenation of oils hydrogenation producing higher alcohols etc..
Petroleum and chemical manufacturing oxygenated products process for the vast majority of selective oxidation process. Selective oxidation products accounted for80% of organic chemical products; the catalyst has high catalytic selectivity first.Selective oxidation catalyst can be divided into gas phase oxidation catalyst andliquid phase oxidation catalyst.
