  2. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.

    The adjacent diagram schematically depicts the major hydrocarbon sources and processes used in producing petrochemicals. [2] [3] [7] [8] Petrochemical feedstock sources. Like commodity chemicals, petrochemicals are made on a very large scale. Petrochemical manufacturing units differ from commodity chemical plants in that they often produce a ...

  6. Cracking (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Cracking_(chemistry)

    Alkenes cause instability of hydrocarbon fuels. [9] Fluid catalytic cracking is a commonly used process, and a modern oil refinery will typically include a cat cracker, particularly at refineries in the US, due to the high demand for gasoline. [10] [11] [12] The process was first used around 1942 and employs a powdered catalyst. During WWII ...

  7. Saturated and unsaturated compounds - Wikipedia

    en.wikipedia.org/wiki/Saturated_and_unsaturated...

    Unsaturated compounds generally carry out typical addition reactions that are not possible with saturated compounds such as alkanes. A saturated organic compound has only single bonds between carbon atoms. An important class of saturated compounds are the alkanes. Many saturated compounds have functional groups, e.g., alcohols.

  8. Petroleum - Wikipedia

    en.wikipedia.org/wiki/Petroleum

    The proportion of light hydrocarbons in the petroleum mixture varies among oil fields. [59] An oil well produces predominantly crude oil. Because the pressure is lower at the surface than underground, some of the gas will come out of solution and be recovered (or burned) as associated gas or solution gas. A gas well produces predominantly ...

  9. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    Bromine test is used to test the saturation of hydrocarbons. [17] The bromine test can also be used as an indication of the degree of unsaturation for unsaturated hydrocarbons. Bromine number is defined as gram of bromine able to react with 100g of product. [18] Similar as hydrogenation, the halogenation of bromine is also depend on the number ...
