A method for processing a gasoline fraction includes the steps of: a) reacting the gasoline fraction in an aromatization unit, and separating the resulting reaction product to obtain a Ccomponent, a Ccomponent, a C-Ccomponent, a Ccomponent and a Ccomponent; b) reacting the resulting C-Ccomponent and the Ccomponent in a cracking and aromatics conversion unit, and separating the resulting reaction product to obtain a Ccomponent, a Ccomponent, a C-Ccomponent, a Ccomponent and a Ccomponent; and c) recycling at least a part of at least one of the C-Ccomponent and the Ccomponent from step b) to the cracking and aromatics conversion unit of step b) for further reaction. The method can convert the gasoline fraction into Caromatic hydrocarbon(s) and produce light olefins and a high-quality light gasoline as byproducts.

A catalyst for producing light aromatics with heavy aromatics, a method for preparing the catalyst, and a use thereof are disclosed. The catalyst comprises a carrier, component (), and component (), wherein component () comprises one metal element or more metal elements selected from a group consisting of Pt, Pd, Ir, and Rh, and component () comprises one metal element or more metal elements selected from a group consisting of IA group, IIA group, IIIA group, IVA group, IB group, IIB group, IIIB group, IVB group, VB group, VIB group, VIIB group, La group, and VIII group other than Pt, Pd, Ir, and Rh. The catalyst can be used for producing light aromatics with heavy aromatics, whereby heavy aromatics hydrogenation selectivity and light aromatics yield can be improved.
