Abstract:

In this paper, the process of isomerization of hydrocarbon raw materials is considered. The purpose of isomerization processes in oil refining is to increase the octane number of petroleum fractions by converting paraffins of normal structure into their isomers having a higher octane number. The raw materials of the isomerization process are light straight–run fractions, the products are isomerizate, which is sent for mixing with reforming and catalytic cracking catalysts. The isomerization process contains a mixture of low-boiling high-octane paraffin hydrocarbons, when compounded with reformat reduces the proportion of aromatic hydrocarbons (including benzene), increases the octane characteristic of the light part of gasoline, improves the fractional composition of commercial gasoline

Keywords: light straight-run fractions, a mixture of low-boiling high-octane paraffin hydrocarbons, reformat, isomerization, catalysts, aromatic hydrocarbons, process diagrams
