  • MAXIMUM OLEFINS PRODUCTION UTILIZING MULTI-STAGE CATALYST REACTION AND REGENERATION
    Publication number: 20210207039
    Abstract: A method and system for increasing olefin production and quality from a hydrocarbon feed comprising a fully integrated multi-stage catalyst regeneration zones with multi-stage reaction zones in series and/or parallel. The multi-stage regeneration with at least one partial and one full burn zone provides an independent control to achieve the lowest possible regenerated catalyst temperature, resulting in highest possible catalyst to oil ratio required to maximize olefins yields through increased catalytic cracking in a multi stage FCC riser/risers.
    Type: Application
