Zusammenfassung: | A method for producing xylene from feedstock oil includes a cracking/reforming reaction step of bringing the feedstock oil into contact with a catalyst to produce monocyclic aromatic hydrocarbons; a separation/recovery step of separating and recovering, from a product obtained by the cracking/reforming reaction step, a fraction A containing monocyclic aromatic hydrocarbons having a 10 vol % distillation temperature of 75° C. or higher and a 90 vol % distillation temperature of 140° C. or lower, a xylene fraction containing xylene, and a fraction B containing monocyclic aromatic hydrocarbons having a 10 vol % distillation temperature of 145° C. or higher and a 90 vol % distillation temperature of 215° C. or lower; and a xylene conversion step of bringing a mixed fraction obtained by mixing the fractions A and B with each other into contact with a catalyst containing a solid acid to convert the mixed fraction into xylene. |
