Title:
METHOD AND SYSTEM FOR TREATING HYDROCARBON-CONTAINING MIXTURE
Document Type and Number:
WIPO Patent Application WO/2022/078370
Kind Code:
A1
Abstract:
Disclosed are a method and system for treating a hydrocarbon-containing mixture. The method comprises the following steps: I) separating the hydrocarbon-containing mixture into a light component and a heavy component; II) reacting the light component obtained in step I) in an aromatization unit, and separating the reaction product into a C5 - component and a C6 + component; III) reacting the heavy component obtained in step I) and optionally the C6 + component obtained in step II) in an aromatic hydrocarbon conversion unit, and separating the reaction product into a C5 - component, a C6-C7 component, a C8 component and a C9 + component; and IV) optionally, performing steam cracking or catalytic cracking on one or both of the C5 - component obtained in step II) and the C5 - component obtained in step III). The method and system can convert a low-value hydrocarbon mixture into C8 aromatic hydrocarbons and crack raw materials, thereby improving the product value.
