The present invention converts hydrocarbon oils containing polycyclic aromatic hydrocarbons to light hydrocarbon distillates, and efficiently and selectively produces monocyclic aromatic hydrocarbons. LPG distillates, gasoline distillates, kerosene distillates, diesel distillates To provide a process for producing monocyclic aromatic hydrocarbons and non-aromatic naphtha distillates, the method for producing hydrocarbon distillates contains polycyclic aromatic hydrocarbons and constitutes an aromatic ring for all carbons in hydrocarbon oils. A hydrocracking step of catalytically cracking a raw material hydrocarbon oil having a ratio of 35 mol% or more in the presence of hydrogen, and converting at least 40% of the boiling point of at least 215 ° C. and distilled portion of the raw material hydrocarbon oil into a distillate of less than 215 ° C., 1 It is characterized by producing the hydrocracking production oil containing 30 volume% or more of cyclic aromatic hydrocarbons. |
