Abstract: The combined process of the medium pressure hydroupgrading (MHUG) and kerosene hydrofinishing (KHF), developed by Fushun research institute of petroleum and petrochemical, was adopted for production of No.3 jet fuel in PetroChina Karamay Petrochemical Co. Ltd. The mixture of coking diesel, FCC LCO and SR diesel was used as feedstock. Industrial application results show that after the jet fuel fraction from MHUG process was deeply hydrofinished under the mild reaction conditions, the aromatics in jet fuel product is reduced from 14.9% to 5.8%, the smoke point rises from 22 mm to 26 mm, in compliant with the quality specification of GB6537-2006.

Key words: jet fuel, medium pressure hydroupgrading, hydrofinishing
