  • Patent number: 11807816
    Abstract: Systems and methods for the catalytic cracking of light hydrocarbons, such as naphtha, to form light olefins and aromatics is disclosed. The systems and methods may include a catalytic cracking process that involves mixing catalyst with a gas and then this mixture is used to contact a hydrocarbon feed, e.g., light straight run naphtha or heavy straight run naphtha. The hydrocarbon feed may be mixed with dry gas such as methane and/or hydrogen to dilute the hydrocarbon feed, before the hydrocarbon feed is contacted with the catalyst/gas mixture.

  • Patent number: 11807819
    Abstract: Systems and methods for processing full range naphtha to produce light olefins are disclosed. The systems and methods include separating the full range naphtha into a light naphtha stream and a heavy naphtha stream and integrating a catalytic cracking with a naphtha reforming to process the light naphtha and heavy naphtha streams.

  • Patent number: 11208599
    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).

  • Publication number: 20210147321
    Abstract: Systems and methods of producing olefins via catalytic cracking are disclosed. Hydrocarbons of a naphtha stream are isomerized by converting straight chain Cn hydrocarbons to branched Cn hydrocarbons, thereby forming an isomerized naphtha stream. The isomerized naphtha stream is subsequently fed to a catalytic cracking unit such that the hydrocarbons of the isomerized naphtha stream form olefins. In the catalytic cracking process, the reaction temperature can be kept lower than 680° C., thereby increasing the reactivity and minimizing catalyst deactivation in the catalytic cracking process.
