1. An oxygen carrier solid in the form of particles for a process for chemical looping redox combustion of a hydrocarbon feedstock, comprising:
a redox active mass constituting between 5% and 75% by weight of the oxygen carrier solid, the redox active mass comprising at least one copper oxide and being capable of transporting oxygen in the chemical looping redox combustion process;
a ceramic matrix within which the redox active mass is dispersed, the ceramic matrix constituting between 25% and 95% by weight of the oxygen carrier solid, the ceramic matrix comprising 100% by weight of at least one oxide having a melting point above 1500° C.;
a porosity such that:
the total pore volume of the oxygen carrier solid, measured by mercury porosimetry, is between 0.05 and 1.2 ml/g,
the pore volume of macropores constitutes at least 40% of the total pore volume of the oxygen carrier solid;
the size distribution of the macropores within the oxygen carrier solid, measured by mercury porosimetry, is between 50 nm and 7 μm.
