    2 per unit of energy than does coal or oil, but more than natural gas. It emits 81% of the CO 2 per kWh produced by oil, 70% of that of coal, and less than 50% of that emitted by coal-generated electricity distributed via the grid. [40] Being a mix of propane and butane, LPG emits less carbon per joule than butane but more carbon per joule than ...

  4. Isobutane - Wikipedia

    en.wikipedia.org/wiki/Isobutane

    Since the longest continuous chain in isobutane contains only three carbon atoms, the preferred IUPAC name is 2-methylpropane but the locant (2-) is typically omitted in general nomenclature as redundant; C2 is the only position on a propane chain where a methyl substituent can be located without altering the main chain and forming the ...

  5. Butane - Wikipedia

    en.wikipedia.org/wiki/Butane

    The operating pressure for butane is lower than operating pressures for halomethanes such as Freon-12 (R-12). Hence, R-12 systems, such as those in automotive air conditioning systems, when converted to pure butane, will function poorly. Instead, a mixture of isobutane and propane is used to give cooling system performance comparable to R-12. [28]

  8. Alkylation unit - Wikipedia

    en.wikipedia.org/wiki/Alkylation_unit

    Unreacted isobutane is recovered and recycled back to the reaction section to mix with the olefin feed. Propane is a major product of the distillation process. Some amount of n-butane that has entered with the feed is also withdrawn as a side product. Propane and butane that have not been separated from the treated olefin pass through the unit.

  9. Isobutylene - Wikipedia

    en.wikipedia.org/wiki/Isobutylene

    Isobutylene is used in the production of a variety of products. It is alkylated with butane to produce isooctane or dimerized to diisobutylene (DIB) and then hydrogenated to make isooctane, a fuel additive.
