  • Deep desulphurization of low sulphur content feedstock
    Patent number: 11492560
    Abstract: The invention pertains to a process for deep desulphurization of low sulphur content feedstock comprising the steps of providing a low sulphur content hydrocarbon feedstock and contacting said hydrocarbon feedstock with a cobalt-molybdenum desulphurizing system or a nickel-molybdenum desulphurizing system in an oxide form in order to obtain a very low sulphur product comprising less than 5 ppm by weight sulphur.
    Type: Grant
    Filed: October 22, 2019
    Date of Patent: November 8, 2022
    Assignee: TOTAL MARKETING SERVICES
    Inventors: Alessandro Chieregato, Jean-Pierre Dath, Stéphane Kressmann

  • Heterogeneous catalysts for the oxidative dehydrogenation of alkanes or oxidative coupling of methane
    Patent number: 10961170
    Abstract: Improved methods of oxidative dehydrogenation (ODH) of short chain alkanes or ethylbenzene to the corresponding olefins, and improved methods of oxidative coupling of methane (OCM) to ethylene and/or ethane, are disclosed. The disclosed methods use boron- or nitride-containing catalysts, and result in improved selectivity and/or byproduct profiles than methods using conventional ODH or OCM catalysts.
