Title:

CATALYTIC CONVERSION METHOD AND SYSTEM FOR PRODUCING MORE PROPYLENE

Document Type and Number:

WIPO Patent Application WO/2020/192490

Kind Code:

A1

Abstract:

A catalytic conversion method and system for producing more propylene. The method comprises the following steps: 1) providing an initial raw material containing an olefin having four or more carbon atoms; 2) pre-treating the initial raw material to obtain a propylene precursor, the propylene precursor containing an olefin having 3×2n carbon atoms, wherein n is an integer greater than or equal to 1; and subjecting the propylene precursor to a catalytic cracking reaction to obtain a reaction product containing propylene. The method and system can effectively improve the yield of propylene.
