Abstract: Maximizing gasoline production in No.1 FCC unit of SINOPEC Jinling Company was introduced. The technical principles to increase gasoline yield were reviewed from the view of FCC feedstock, catalyst, reaction severity and product separation. Technical measures, such as adding heavy diesel fractions in feed to reduce residue blended ratio and improve feedstock properties; optimizing operation conditions to reach full capacity production; broadening the gasoline boiling range by increase gasoline dry point and decrease the overlapping of gasoline and diesel fractions, were proposed and realized to enhance the gasoline yield.

Key words: gasoline, fluid catalytic cracking, optimization
