WebC4 Isomerization. The purpose of the C4 isomerization unit is to convert normal butane (n-C4) into isobutane to feed the alkylation unit.. Isobutane is produced in a variety of conversion units in a refinery.However, when a refinery has an alkylation unit, there is usually a need to make additional isobutane "on purpose" to keep the alky full. WebSuch isobutane feed does not normally contain any significant level of contaminants. Mechanism [ edit] The catalyst protonates the alkenes (propene, butene) to produce reactive carbocations, which alkylate isobutane. The reaction is carried out at mild temperatures (0-30 °C) in a two-phase reaction. climbing conveyorWebNormal butane, C4H10, is to be isomerized to isobutane in a plug-flow reactor.

WebNormal butane, C4H10, is to be isomerized to isobutane in a plug-flow reactor. Isobutane is a valuable product that is used in the manufacture of gasoline additives. For example, isobutane can be further reacted to form iso-octane. The selling price of n-butane was $0.44/kg, while the trading price of isobutane was $0.68/kg. WebN-butane equilibrium isomerization reaction shifts to the side of isobutane generation upon temperature decrease (picture 1). Therefore the process becomes efficient only in case of temperatures below 250 оС. Space velocity decrease at permanent temperature and other conditions leads to decrease of isobutane content in a product.
