Abstract

Provided is a method for producing aromatic hydrocarbons, by which a feedstock containing a hydrogenation-treated oil of a thermally cracked heavy oil obtainable from an ethylene production apparatus is brought into contact with a catalyst for monocyclic aromatic hydrocarbon production containing a crystalline aluminosilicate, and thereby aromatic hydrocarbons are produced. A raw material having an end point of the distillation characteristics of 400° C. or lower is used as the feedstock. The contact between the feedstock and the catalyst for monocyclic aromatic hydrocarbon production is carried out at a pressure of 0.1 MPaG to 1.5 MPaG.
