METHOD AND SYSTEM FOR PRODUCING LIGHT OLEFIN FROM POOR OIL

Document Type and Number:

WIPO Patent Application WO/2020/177652

Kind Code:

A1

Abstract:

A method and system for producing a light olefin from a poor oil. The method comprises the following steps: performing thermal conversion reaction on a poor oil in the presence of hydrogen to obtain a conversion product; separating the obtained conversion product to obtain a first separation product; separating the first separation product to obtain a modified oil and residues; performing hydrogenation modification on the obtained modified oil to obtain a hydrogenation modified oil; separating the hydrogenation modified oil to obtain a hydrogenation modified heavy oil; and performing catalytic pyrolysis on the hydrogenation modified heavy oil to obtain a catalytic pyrolysis product containing a light olefin. The method and system not only can achieve efficient and green conversion of a poor oil, but also can achieve high-value utilization of the poor oil, i.e., producing a light olefin.
