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 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.
