Abstract: A device for accumulation and exchange of thermal energy of solar origin is provided. The device includes: a casing which defines an internal compartment and has an irradiation opening configured to allow the entry of concentrated solar radiation, the opening puts in direct communication the inner compartment with the external environment being devoid, in use, of closure or screen means; a bed of fluidizable solid particles, received within the inner compartment of the casing, the bed has an operative region directly exposed to the concentrated solar radiation that enters through the opening, in such a way that the particles of the operative region absorb thermal energy from solar radiation; and fluidization means of the bed of particles, configured to adduce a fluidizing gas into the compartment at the operative region.

Abstract: The invention relates to a plant and a process for the looping-type combustion of solid carbon-containing fuels with a carbon dioxide (CO2) flow output. Said process carries out the conversion of carbon without the help of solid carriers of the MyOx type, 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 O2.
