The invention relates to a plant and a process for the looping-type combustion of solid carbon-containing fuels with a carbon dioxide (CO) flow output. Said process carries out the conversion of carbon without the help of solid carriers of the MOtype, or of sulphate/sulphide type, and comprises the steps of: (i) Oxidation, wherein the carbon-containing solids are contacted with a gaseous flow comprising oxygen, for a time period and at a temperature sufficient to allow formation of a surface oxidized complex; (ii) Desorption, wherein the surface oxidized complexes generated by adsorption of oxygen in item (i) are released in a gaseous form by decomposition in the absence of O.
