摘要： A process is disclosed for contacting feed with mixed catalyst in a secondary reactor that is incorporated into an FCC reactor. The mixed catalyst used in the secondary reactor is regenerated catalyst from a regenerator that regenerates spent catalyst from an FCC reactor that is mixed with spent catalyst from either the FCC reactor or the secondary reactor. The mixing of spent and regenerated catalyst reduces the catalyst temperature and tempers catalyst activity to inhibit both thermal and catalytic cracking reactions.

摘要： Integration of gas oil and light olefin catalytic cracking zones with a pyrolytic cracking zone to maximize efficient production of petrochemicals 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.

摘要： A process for the dual riser contacting of a primary feed and a secondary recycle feed fraction uses independent recovery of the separate streams from the riser cracking zone to improve the product yields and properties. Separate recovery segregates the upgraded recracked components from the rest of the primary cracked products. The benefits of selective of recracking are lost if the upgraded products from the recycle stream become recombined with the primary cracked product. The selectively recovered recycle feed may undergo hydroprocessing to hydrogenate, hydrocrack and/or hydrotreatment before recracking. The process can also make highly efficient use of the high residual activity in the catalyst that has contacted the secondary feed.

摘要翻译： 主进料和次级再循环进料部分的双提升管接触的方法使用独立回收来自提升管裂化区的单独流，以改善产物产率和性质。 单独的回收将升级后的重新组装与其他主要裂解产品隔离开来。 如果来自再循环流的升级产品与初级裂解产物重新组合，则重新选择性的优点将丧失。 选择回收的再循环进料可以在重新加工之前进行加氢处理以氢化，加氢裂化和/或加氢处理。 该方法还可以高效地利用已经接触二次进料的催化剂中的高残留活性。
