The narrow distillates of different distillation temperature range were obtained by true boiling point distillation apparatus to precise separation of hydrogenated diesel,and the yield distribution and hydrocarbon composition distribution of narrow distillates were analyzed.The analysis results showed that with the distillation range temperature rise,narrow distillate yield reduced gradually,alkane in hydrogenated diesel mainly enriched in the narrow distillate of high distillation range temperature,and cyclanes and aromatic hydrocarbons mainly enriched in the narrow distillate of low distillation range temperature.After the coker light gas oil hydrocracking blending different narrow distillates,the distillate yield of hydrocrackate at 65~175 ℃ was increased and the distillate yield was decreased after the temperature above 175 ℃.The properties of hydrocrackate were different due to the different hydrocarbon compositions of narrow distillates.The aromatic potential value of 65~175 ℃ distillate obtained by blending narrow distillate rich in cycloalkanes and aromatics was the highest,and the hexadecane index of >175 ℃ distillate obtained by blending narrow distillate of alkanes was the highest.
