Abstract: In order to increase jet fuel production, the No.2 kerosene hydrogenation unit of SINOPEC-SK (Wuhan) Petrochemical Company Limited was revamped by using the jet fuel hydrofining technology (JeFIT) developed by the SINOPEC Research Institute of Petroleum Processing. After retrofitting, the unit was successfully started, and the technical calibration and long-term operation test of industrial unit were carried out. The results of calibration showed that the final distillation point was about 263 ℃, the color of the refined kerosene was +30, the basic nitrogen content was less than 1 μg/g, thermal oxidation stability breaking point temperature was more than 320 ℃，static stability oxidation precipitation was less than 4.6 mg/(100 mL)，and other indexes all met the quality requirements of China No.3 jet fuel. The long-term operation of the industrial plant showed that the application of JeFIT technology could realize the safe and stable long-term operation of the plant and the goal of increasing the production of jet fuel by more than 30%.
