This article discusses the role and purpose of the process of isomerization of paraffin hydrocarbons
in the oil refining and petrochemical industries. Most often, the paraffin isomerization process is used to increase the
octane number of the fractions of the direct and secondary distillation of gasoline containing hydrocarbons such as
pentane and hexane. The resulting isomerates are used as a necessary component of the catalytic reforming of gasoline
to produce high octane gasoline. Currently, the problem of increasing the octane number of gasoline by isomerization of
pentane and hexane is of particular importance due to the worldwide trend to abandon the use of tetraethyl lead, which
causes great damage to the environment. The products of the isomerization process, in turn, contribute to the development of the oil and petrochemical industry, the synthesis of hydrocarbons and transportation, in general, the
prosperity of the country's economy.
