Abstract

Abstract
The process of fluid catalytic cracking (FCC) is the main conversion process in which heavy oil fractions convert into lighter fractions. Liquid catalytic cracking products, FCC gasoline and light cyclic oil, are used for blending motor gasoline or diesel fuel. Stringent environmental and legal regulations require reduction of the content of sulphur and hardly combustible aromatics and olefins in motor fuels. Chromatographic techniques make it possible to monitor changes in the content of various hydrocarbons groups at catalytic reactions. The paper presents the determination of group composition of FCC gasoline through gas chromatography, and that of aromatic content according to the number of aromatic rings in FCC gasolines, their fractions and light cyclic oil, using liquid chromatography. Compared were cracking products obtained from feeds of various origins (high sulphur and low sulphur oil).
