Abstract: The growth of domestic jet fuel demand promotes the enhancement of jet fuel hydrogenation capacity of refineries. In 2015, SINOPEC Anqing Petrochemical Company transformed the catalytic gasoline hydrogenation unit into jet fuel hydrogenation unit, using the original FGH-21/FGH-31 catalyst to produce refined jet fuel products meeting the technical requirements of No.3 jet fuel. At the end of 2019, the capacity expansion project was implemented, the production capacity of jet fuel hydrogenation unit was increased from 0.4 MM TPY to 0.8 MM TPY, and the catalyst was replaced by FH-40A catalyst. The results of industrial operation show that under the conditions of 2.9 MPa reaction pressure, hydrogen to oil ratio no less than 80 and reaction temperature about 270 ℃, the modified jet fuel hydrogenation unit can produce qualified No.3 jet fuel stably, achieving the goal of improving the product structure and increasing the economic benefits of the enterprise.
