Abstract: FH-40B catalyst developed by SINOPEC Fushun Research Institute of Petroleum and Petrochemicals was commercially used in a 1.4 Mt/a jet fuel hydrogenation unit of a petrochemical refinery. The calibration results showed that the qualified No.3 jet fuel (in compliant with GB 26537—2006) can be produced from the feed with 0.14% μg/g sulfur. The jet fuel produced is characterized by the mass fraction of mercaptan sulfur of 3μg/g, smoking point of 24.5 mm, freezing point of -57.2℃ and the volume fraction of naphthalenes of 0.36% at reaction conditions of 265 ℃,1.75 MPa, hydrogen/oil volume ratio of 100 and LHSV of 2.95 h－1. The commercial results demonstrated that the catalyst FH-40B has a good activity and stability, the catalyst deactivation rate is 0.021 ℃/d, the pressure drop of the catalyst bed is smooth, which is favor of long-running for the unit.
