  • Process for producing ethylene
    Patent number: 11091412
    Abstract: A process for producing ethylene includes the steps of: (1) catalytically cracking a raw material hydrocarbon to obtain a first stream containing propylene; (2) separating the first stream to obtain a C3 component stream; and (3) disproportionating the C3 component stream to obtain an ethylene stream. This process reduces the overall energy consumption of the production process and increases the total yield of the ethylene while obtaining a polymerization-grade ethylene.
    Type: Grant
