摘要：
A method for producing aromatic hydrocarbons, the method including: (a) bringing a feedstock oil such as an LCO into contact with an aromatic production catalyst to obtain a reaction product containing aromatic hydrocarbons, (b) separating the reaction product into a tower top fraction and a tower bottom fraction using a distillation tower, (c) separating the tower top fraction into a crude aromatic fraction containing an LPG fraction, and an off-gas containing hydrogen, (d) separating the crude aromatic fraction containing an LPG fraction into an LPG fraction and a crude aromatic fraction, (e) separating the off gas containing hydrogen into hydrogen and an off-gas, and (f) using the hydrogen obtained in step (e) to hydrotreat the crude aromatic fraction, thereby obtaining an aromatic fraction.
