Abstract

Abstract Change of the FCC gasoline distillation limits is one of the methods for solving the sulphur problem in the FCC gasoline used now at Sisak Oil Refinery until the modernization of its units. Objective of this paper has been to show how the FCC gasoline properties change by using this method, and how this change gets reflected on the quantity of components limited by application of the present European specifications for unleaded petrol – quantities of sulphur, as well as aromatic and olefin hydrocarbons. For this purpose, comparison has been made between physical and chemical properties of the total FCC gasoline fraction created by the fluid catalytic cracking in our refineries from high- and low-level sulphur crudes, fractions from which the FCC gasoline is made, and fractions with changed distillation limits.
