Title:

GASOLINE COMPONENT PROCESSING METHOD AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2022/083725

Kind Code:

A1

Abstract:

Disclosed are a gasoline component processing method and system, the method comprising the following steps: a.) reacting gasoline components in an aromatization unit, and separating the reaction products to obtain a C4-component, a C5 component, a C6-C7 component, a C8 component and a C9 + component; b) reacting the obtained C6-C7 component and the C9 + component in a cracking and aromatization unit, and separating the reaction products to obtain a C4-component, a C5 component, a C6-C7 component, a C 8 component and a C9 +component; and c) recirculating at least part of at least one of the C6-C7component and the C9 + component obtained in step b) to the cracking and aromatization unit for continued reaction. The present method and system may effectively convert a gasoline component into C8 aromatics, and co-produce low-carbon olefins and high-quality light gasoline, achieving efficient comprehensive utilization.
