Abstract: A case study on the potential of enhancing gasoline production was carried out by analyzing the components of gasoline pool in this study and the specifications of gasoline products. It was obvious that gasoline blending components from FCC unit and CCR unit were the dominant components. Thus measures, such as providing more feedstocks for FCC and CCR units, maximizing the production load of these two units, and recycling heavy CCR gasoline fraction to FCC unit were adopted. Successful results showed that the production of gasoline increased 172.6 kt (over the design value) in 2010, which indicated an economic benefit of 86.13 million RMB was obtained.

Key words: production optimization, gasoline , catalytic cracking, continuous reforming
