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.
