Title:
METHOD FOR UPGRADING CATALYTICALLY CRACKED GASOLINE
Document Type and Number:
WIPO Patent Application WO/2020/052143
Kind Code:
A1
Abstract:
Provided is a method for upgrading catalytically cracked gasoline. The method comprises: firstly, removing diolefins, thiols, and thioether from full-fraction FCC gasoline under the action of a pre-hydrogenation catalyst in a pre-hydrogenation reactor; and then, subjecting the pre-hydrogenation product to selective hydrodesulfurization under the action of a hydrodesulfurization-isomerization catalyst, while isomerizing the linear olefins into single branched olefins or single branched alkanes, to obtain a clean gasoline product with low olefin and ultra-low sulfur contents and a high octane value.
