Title:
オレフィンのための統合された接触分解および水蒸気熱分解法
Document Type and Number:
Japanese Patent JP4620427
Kind Code:
B2
Abstract:
Integration of gas oil and light olefin catalytic cracking zones with a pyrolytic cracking zone to maximize efficient production of petrochemical feedstocks is disclosed. Integration of the units in parallel allows production of an overall product stream with maximum ethylene and/or propylene by routing various feedstreams and recycle streams to the appropriate cracking zone(s), e.g. ethane/propane to the steam pyrolysis zone and C4 - C6 olefins to the light olefin cracking zone. This integration enhances the value of the material balances produced by the integrated units even while using the lowest value feedstreams.
