  2. Naphthenic oil - Wikipedia

    en.wikipedia.org/wiki/Naphthenic_oil

    Naphthenic oils have excellent cooling and insulating properties because of a low viscosity index. The good solubility of the oils is also important for enhanced compatibility with seals and gaskets, for example. 2. Process oils. Naphthenic oils are used in a large number of chemical processes due to their good solvent power.

  3. Naphtha - Wikipedia

    en.wikipedia.org/wiki/Naphtha

    Naphtha is used to dilute heavy crude oil to reduce its viscosity and enable/facilitate transport; undiluted heavy crude cannot normally be transported by pipeline, and may also be difficult to pump onto oil tankers. Other common dilutants include natural-gas condensate and light crude. However, naphtha is a particularly efficient dilutant and ...

  4. Petroleum naphtha - Wikipedia

    en.wikipedia.org/wiki/Petroleum_naphtha

    Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil [1] [2] [3] with CAS-no 64742-48-9. [4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or ...

  5. Hydrodesulfurization - Wikipedia

    en.wikipedia.org/wiki/Hydrodesulfurization

    Hydrodesulfurization or hydrodesulphurisation (Commonwealth English; see spelling differences) (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils.

  6. Naftalan oil - Wikipedia

    en.wikipedia.org/wiki/Naftalan_oil

    Naftalan or Naphtalan is a type of crude oil.It is named after Naftalan, Azerbaijan, where it is found.It is known for its use in alternative medicine.. Naftalan crude oil is too heavy for normal export uses (unlike Azerbaijan's plentiful Caspian Sea oil): it contains about 50 percent cycloalkanes (naphthenic hydrocarbons).

  7. Base oil - Wikipedia

    en.wikipedia.org/wiki/Base_oil

    The most common one is a type of paraffinic crude oil, although there are also naphthenic crude oils that create products with better solubility and very good properties at low temperatures. By using hydrogenation technology, in which sulfur and aromatics are removed using hydrogen under high pressure, extremely pure base oils can be obtained ...

  9. Catalytic reforming - Wikipedia

    en.wikipedia.org/wiki/Catalytic_reforming

    The heavy reformate is high in octane and low in benzene, hence it is an excellent blending component for the gasoline pool. Benzene is often removed with a specific operation to reduce the content of benzene in the reformate as the finished gasoline has often an upper limit of benzene content (in the UE this is 1% volume).
