  • Catalytic caustic desulfonylation
    Patent number: 11008522
    Abstract: A caustic desulfonylation method and system comprising a reactor vessel with a solid carbonaceous selectivity promoter provided therein, a liquid feed input of the reactor vessel configured to receive a source of caustic, a hydrocarbon feed comprising oxidized sulfur containing compounds and a gas feed input of the reactor vessel configured to receive a source of hydrogen. The caustic desulfonylation method and system further includes an output of the reactor vessel releasing the caustic and an upgraded hydrocarbon product with sulfur content less than the sulfur content of the hydrocarbon feed received by the liquid feed of the reactor vessel.
    Type: Grant
    Filed: October 11, 2019
    Date of Patent: May 18, 2021
    Assignees: AUTERRA, INC., CENOVUS ENERGY INC.
    Inventors: Jonathan Rankin, Sarah Briggs

  • Reaction system, methods and products therefrom
    Patent number: 9828557
    Abstract: A reaction system and method for removing heteroatoms from oxidized-heteroatom-containing hydrocarbon streams and products derived therefrom are disclosed. An oxidized-heteroatom-containing hydrocarbon feed is reacted in a reaction system thereby forming non-ionic hydrocarbon products. The products derived therefrom are useful as transportation fuels, lubricants, refinery intermediates, or refinery feeds.
