  2. Ethane - Wikipedia

    en.wikipedia.org/wiki/Ethane

    Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː-/ EE-) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum ...

  3. Steam cracking - Wikipedia

    en.wikipedia.org/wiki/Steam_cracking

    The products produced in the reaction depend on the composition of the feed, the hydrocarbon-to-steam ratio, and on the cracking temperature and furnace residence time. Light hydrocarbon feeds such as ethane, LPGs, or light naphtha give mainly lighter alkenes, including ethylene, propylene, and butadiene.

  4. Cracking (chemistry) - Wikipedia

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

    The products produced in the reaction depend on the composition of the feed, the hydrocarbon-to-steam ratio, and on the cracking temperature and furnace residence time. Light hydrocarbon feeds such as ethane, LPGs or light naphtha give product streams rich in the lighter alkenes, including ethylene, propylene, and butadiene.

  5. Syngas - Wikipedia

    en.wikipedia.org/wiki/Syngas

    Syngas is produced by steam reforming or partial oxidation of natural gas or liquid hydrocarbons, or coal gasification. [6] C + H 2 O → CO + H 2 [1] CO + H 2 O → CO 2 + H 2 [1] C + CO 2 → 2CO [1] Steam reforming of methane is an endothermic reaction requiring 206 kJ/mol of methane: CH 4 + H 2 O → CO + 3 H 2

  6. Petrochemical - Wikipedia

    en.wikipedia.org/wiki/Petrochemical

    Methane, ethane, propane and butanes obtained primarily from natural gas processing plants. Methanol and formaldehyde. In 2007, the amounts of ethylene and propylene produced in steam crackers were about 115 Mt (megatonnes) and 70 Mt, respectively. [5] The output ethylene capacity of large steam crackers ranged up to as much as 1.0 – 1.5 Mt ...

  7. Catalytic reforming - Wikipedia

    en.wikipedia.org/wiki/Catalytic_reforming

    A side reaction is hydrogenolysis, which produces light hydrocarbons of lower value, such as methane, ethane, propane and butanes. Continuous Catalytic reforming (CCR) unit In addition to a gasoline blending stock, reformate is the main source of aromatic bulk chemicals such as benzene , toluene , xylene and ethylbenzene , which have diverse ...

  8. Liquefied natural gas - Wikipedia

    en.wikipedia.org/wiki/Liquefied_natural_gas

    The gas stream is typically separated into the liquefied petroleum fractions (butane and propane), which can be stored in liquid form at relatively low pressure, and the lighter ethane and methane fractions. These lighter fractions of methane and ethane are then liquefied to make up the bulk of LNG that is shipped.

  9. Ethylene - Wikipedia

    en.wikipedia.org/wiki/Ethylene

    Ethylene is produced by several methods in the petrochemical industry. A primary method is steam cracking (SC) where hydrocarbons and steam are heated to 750–950 °C. This process converts large hydrocarbons into smaller ones and introduces unsaturation. When ethane is the feedstock, ethylene is the product.
