  • 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
    Date of Patent: February 20, 2024

  • CATALYTIC CRACKING OF LIGHT NAPHTHA OVER DUAL RISER FCC REACTOR
    Publication number: 20210269725
    Abstract: Systems and methods for producing light olefins and aromatics from light naphtha are disclosed. The light naphtha is fed to a first catalyst riser to crack the C5 to C7 hydrocarbons in the light naphtha stream. The cracked naphtha stream is fractionated to produce a stream comprising primarily C4 to C6 hydrocarbons or a stream comprising primarily C5 to C12 hydrocarbons. When the stream comprising primarily C4 to C6 hydrocarbons is fed to the second catalyst riser, the product stream from the second riser comprises light olefins as the main product. When the stream comprising primarily C5 to C12 hydrocarbons is fed to the second riser, the product stream from the second riser comprises aromatics as the main product.
