Abstract

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 (1), and component (2), wherein component (1) comprises one metal element or more metal elements selected from a group consisting of Pt, Pd, Ir, and Rh, and component (2) 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.
