Abstract
The paper investigates the impact of FCC feed hydrotreatment on the yield of catalytic cracking products. Monitored were the yields of gasoline fractions, LPG and cyclic oil, and the values of octane number and sulphur content in gasoline fractions. Research was performed at the HDS/MHC and FCC processes at INA Rafinerija nafte Rijeka.
The results of the research conducted have shown that the hydrotreatment of the catalytic cracking feed impacts an increase in the yield of gasoline and LPG fractions, with a reduced yield of light cyclic oil. Also, the application of hydrotreated feed achieves a lower sulphur content, as well as lower values of the gasoline octane number. The latter, unwanted effect, is associated primarily with the conversion of aromatic hydrocarbons into naphthenic in the hydrotreatment process of the catalytic cracking feed.
