WitrynaFull-range naphtha (FRN) is a mixture of C5–C12 hydrocarbons. The isomerization unit is used to boost the RON of light naphtha (C5 and C6), while the reforming unit improves the RON of heavy naphtha (C8+). Refineries with both isomerization and reforming units cannot economically utilize all of the molecules in FRN. Witrynaand heavy naphtha. The objective of this process step is to increase the octane value of the light naphtha stream. Gasoline components can be converted from light naphtha streams through isomerization units. The isomerization reaction of C4, C5 and C6 factions occurs over a platinum catalyst. general sand products west bridgewater ma https://juancarloscolombo.com
