Abstract: The monocyclic and bicyclic aromatic hydrocarbons,rich in FCC light cycle oil （LCO）, can be hydrogenated into naphthenes which are high-density jet fuel components. By analyzing the hydrocarbon composition of the narrow fractions of LCO, the range of feedstock fraction suitable for producing high density jet fuel was determined. A high density jet fuel component with a density (20 ℃) greater than 0.835 g/cm³ was obtained with the optimized light fraction of LCO as feedstock under suitable hydrogenation conditions. Furthermore, the effect of process conditions on the properties of high density jet fuel was studied. The technology of producing high density jet fuel by catalytic hydrogenation of LCO can provide more choices for refinery enterprises on the processing route of LCO.
