Optimize isomerization reactor temperatures and component RON

Isomerate is useful because it is paraffinic and contains no benzene, aromatics or sulfur. This pentane and hexane fraction of crude oil is known as light naphtha. The main objective of reactions is to increase the research octane number (RON) of the components. Decreasing fuel consumption without changing the product RON of isomerization units is discussed here.

One of the components of a refinery’s gasoline pool is isomerate, which is created mainly from isomers of pentane and hexane fraction by turning straight-chain alkanes into branched molecules (Eq.1).      (1) Isomerate is useful because it is paraffinic and contains no benzene, aromatics or sulfur. This pentane and hexane fraction of crude oil is known as light naphtha. The main objective of reactions is to increase the research octane number (RON) of the components. Decreasing fuel consumption without changing the product RON of isomerization units is discussed here. Light straight-run naphtha (LSRN) is a fractionation cut of crude oil that contains C5 and C6 hydrocarbons. To formulate g
