摘要:
A method for producing aromatic hydrocarbons by bringing a feedstock derived from a fraction containing a light cycle oil produced in a fluid catalytic cracking into contact with a catalyst containing a crystalline aluminosilicate, wherein the proportion of the naphthene content within the feedstock is adjusted so as to be greater than the proportion of the naphthene content in the fraction containing the light cycle oil, and the contact between the feedstock and the catalyst is performed under a pressure within a range from 0.1 MPaG to 1.0 MPaG.
