The present invention concerns a device and a process for the storage and restitution of heat which comprises at least two concentric heat storage volumes (TES, TES, TES). The walls () delimiting these storage volumes are configured in a manner such that the thickness of the wall delimiting the central storage volume is greater than the thickness of the wall delimiting the peripheral storage volume.

System and method of heat storage and release comprising at least two concentric heat storage volumes

A device that firstly allows temporary storage of a certain quantity of catalyst and, secondly, allows putting back into circulation of this quantity of catalyst in regenerative reforming installations following an interruption in the circulation of the catalyst.

The invention relates to a container () for a heat storage and restitution system, comprising a vessel in which a gas is circulating in order to be cooled or heated. The vessel is limited by a first jacket formed from concrete () surrounded by a thermally insulating layer (), which is itself surrounded by a steel shell (). The vessel comprises at least two modules (), each comprising a double wall formed from concrete and a perforated base () limiting at least two volumes (and) which are each capable of containing a fixed bed of particles of a material for storage and restitution of heat (). The modules are disposed one above the other in a centered manner such that the double wall formed from concrete forms the first jacket formed from concrete () and a second jacket formed from concrete ().
