  • Selective treatment of FCC gasoline for removal of sulfur, nitrogen, and olefin compounds while maximizing retention of aromatic compounds
    Patent number: 12716035
    Abstract: Systems and processes for the treatment of a naphtha range hydrocarbon feedstock comprising sulfur-containing compounds, nitrogen-containing compounds, olefins, diolefins, and aromatics. The systems and processes are configured to treat the naphtha range hydrocarbon feedstock to convert the sulfur-containing compounds, nitrogen-containing compounds, and olefins, diolefins while less than 2 wt % aromatics are hydrogenated, producing an olefin lean overheads fraction comprising less than 0.2 wt % olefins and less than 100 mg/kg sulfur and an aromatics rich fraction comprising less than 50 ppmw olefins, less than 0.5 ppmw sulfur and less than 0.5 ppmw nitrogen.
    Type: Grant
    Filed: October 13, 2023
    Date of Patent: August 25, 2026
    Assignee: Lummus Technology LLC
    Inventors: Rama Rao Marri, Zhiliang Wang, Liang Chen, Marc Andrew Laurin, Yongqiang Xu, Manoj Som, Robert Pham, Brian Boeger
