  • Publication number: 20230407193
    Abstract: 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 C4? component, a C5 component, a C6-C7 component, a C8 component and a C9+ component; b) reacting the resulting C6-C7 component and the C9+ component in a cracking and aromatics conversion unit, and separating the resulting reaction product to obtain a C4? component, a C5 component, a C6-C7 component, a C8 component and a C9+ component; and c) recycling at least a part of at least one of the C6-C7 component and the C9+ component from step b) to the cracking and aromatics conversion unit of step b) for further reaction. The method can convert the gasoline fraction into C8 aromatic hydrocarbon(s) and produce light olefins and a high-quality light gasoline as byproducts.

  • Patent number: 11065604
    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.
