Title:

PROCESS FOR PRODUCING ETHYLENE

Document Type and Number:

WIPO Patent Application WO/2019/042449

Kind Code:

A1

Abstract:

The present invention relates to a process for producing ethylene, comprising steps of: (1) catalytically cracking a hydrocarbon feedstock to obtain a first stream comprising propylene; (2) separating the first stream to obtain a C3 component stream; and (3) disproportionating the C3 component stream to obtain an ethylene stream. The process for producing ethylene of the present invention can greatly reduce overall energy consumption of a production process while obtaining polymerization grade ethylene and can also increase total ethylene yield.
