  • Macroporous oxygen carrier solid with an oxide ceramic matrix, method for the preparation thereof, and use thereof for a chemical-looping oxidation-reduction method
    Patent number: 11717811
    Abstract: The invention relates to an oxygen carrier solid, its preparation and its use in a method of combustion of a hydrocarbon feedstock by active mass chemical-looping oxidation-reduction, i.e. chemical-looping combustion (CLC). The solid, which is in the form of particles, comprises an oxidation-reduction active mass composed of metal oxide(s) dispersed in a ceramic matrix comprising at least one oxide with a melting point higher than 1500° C., such as alumina, and has, initially, a specific macroporous texture. The oxygen carrier solid is prepared from an aqueous suspension containing precursor oxide grains for the ceramic matrix that have a specific size, by a spray-drying technique.
    Type: Grant

    Date of Patent: August 8, 2023
    Assignees: IFP ENERGIES NOUVELLES, TOTAL RAFFINAGE CHIMIE
    Inventors: Arnold Lambert, Mathieu Michau, Delphine Marti, Elodie Comte
  • Macroporous oxygen carrier solid with a refractory feldspar/feldspathoid, method for the preparation thereof, and use thereof in a chemical-looping oxidation-reduction method
    Patent number: 11071971
    Abstract: The invention relates to an oxygen carrier solid, its preparation and its use in a method of combustion of a hydrocarbon feedstock by active mass chemical-looping oxidation-reduction, i.e. chemical-looping combustion (CLC). The solid, which is in the form of particles, comprises an oxidation-reduction active mass composed of metal oxide(s) dispersed in a ceramic matrix comprising at least at least one feldspar or feldspathoid with a melting point higher than 1500° C., such as celsian, and has, initially, a specific macroporous texture. The oxygen carrier solid is prepared from a precursor of the ceramic matrix, obtained from a macroporous zeolitic material with zeolite crystals of a specific size, and a precursor of the oxidation-reduction active mass.
