Chemistry and Technology of Fuels and Oils Aims and scope

In this paper the possibility of using narrow fractions of catalytically cracked hydrotreated gasoline with a relatively low octane number in catalytic reforming feedstock is examined. This problem is important in cases where the operation of an oil refinery is aimed more at the production of petrochemical products. Here the use of straight-run gasoline fractions as feedstock for pyrolysis plants can lead to a shortage of high-octane fuel components. The group composition of narrow fractions of catalytically cracked hydrorefined gasoline was investigated. It was shown that the octane characteristics of the narrow gasoline fractions vary nonlinearly with increase in the boiling point of the fraction. A relationship was established between the group hydrocarbon composition of catalytic-cracking gasoline narrow fractions and their octane characteristics. This can be estimated by using a characterizing coefficient that is the ratio of the sum of aromatic and olefinic hydrocarbons to the sum of paraffins and naphthenes.
