  • Process for catalytic cracking of naphtha using multi-stage radial flow moving bed reactor system
    Patent number: 11905467
    Abstract: System and method for producing olefins are disclosed. The method includes using a radial flow moving bed reactor system to catalytically crack paraffins, in multiple stages with continuous catalyst regeneration, to form olefins. The system includes inter-stage heaters to facilitate increase in yield of olefins.
    Type: Grant
    Filed: July 2, 2019

  • PROCESS FOR CATALYTIC CRACKING OF NAPHTHA USING RADIAL FLOW MOVING BED REACTOR SYSTEM
    Publication number: 20200157435
    Abstract: A method of catalytically cracking liquid hydrocarbons is disclosed. The method includes the use of one or more radial flow moving bed reactors. The method may include mixing a liquid hydrocarbon stream comprising primarily C5 and C6 hydrocarbons with water or a dry gas to form a feed mixture and flowing the feed mixture into the one or more radial flow moving bed reactors in a manner so that the feed mixture flows radially inward or radially outward through the moving catalyst bed and thereby contacts the catalyst particles under reaction conditions to produce a hydrocarbon stream comprising light olefins (C2 to C4 olefins).
