The present invention relates to a process for the partial hydrogenation and hydrocracking process in the presence of a hydrocracking catalyst from an oil rich in polycyclic aromatic compounds including pyrolysis fuel oil (PFO) and light cycle oil (LCO) The present invention relates to a method for producing aromatic hydrocarbons through hydrodesulfurization / denitrification processes and hydrocracking reaction processes according to characteristics of polycyclic aromatics (Sulfur Compounds, Nitrogen Compounds, Aromatic Content) Process and separation process) to produce a high yield aromatic product. The present invention provides a process for producing an aromatic product in which the stability and durability of the catalyst are improved by synthesizing and using a metal-substituted zeolite having different pore size and acid strength by different conditions (substitution type and concentration) do.
