| Alkylation produces high octane gasolines from isobutane and butene, which are gassy molecules containing 4 carbon atoms. |
| Alkylation combines light olefins and isobutane, thus providing refiners an opportunity to increase their crude barrel value. |
| Alongside it lies the heat exchanger, a system of interlaced cylinders and tubes in which the geothermal water and isobutane circulate. |
| Butane and isobutane will be assessed separately as part of the Government's medium priorities. |
| The end result is the addition of isobutane to isobutylene to form isooctane, the molecule that is the basis of octane ratings seen at the gas pumps. |
| However, there are two different butanes, C4H10, and these two molecules, called butane and isobutane, are constitutional isomers. |
