摘要： 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.

摘要： 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.

摘要： The present invention relates to a method for impregnating a porous body (14) by a suspension (12) containing at least partly particles, said body comprising a multiplicity of channels (16) delimited by porous walls (22) extending from one (18) of the faces to the other (20) face of said body, part of said channels being obstructed at one face and the other part of the channels being obstructed at the other face.According to the invention, the method consists in: making a suspension whose particle size distribution meets a DV90/Dpores ratio below 0.25 and whose viscosity is such that said suspension is brought inside the walls while depositing part of the particles on the surface of the pores of the walls, communicating one (18, 20) of the faces of body (14) with an enclosure (30) containing the suspension, feeding the suspension into the body, exerting a force on the suspension introduced so that said suspension flows through the walls, passing a fluid through the walls.
