Abstract: The revamping of FCCU followed by the application of MIP technology at Jilin Petrochemical Company was introduced. After revamping，the product distribution and gasoline properties are improved. The total liquid yield is increased by 0.3%, the olefin content in gasoline reduced by 5%. The RON increased by 1.6, up to 89, meeting the requirement for gasoline blending. Propylene content in LPG increased by over 3.0 percentage points. The properties of diesel and slurry become worse, indicating the effective use of hydrogen in the reaction process.

Key words: MIP, gasoline, olefin, octane number, propylene, coking
