Abstract: Adsorbent agglomerate having an inner region and a superposition of layers of adsorbent particles, the layers of adsorbent particles succeeding each other starting from the inner region, enveloping the inner region, each of the adsorbent particles having a volume termed particle volume, at least two layers of adsorbent particles constituting mutually hierarchical layers, the at least two layers being the layers of adsorbent particles furthest from the inner region, in which adsorbent agglomerate the adsorbent particles constituting each of the hierarchical layers preceding a following hierarchical layer succeeding it have an average particle volume less than the average particle volume of the adsorbent particles constituting the following hierarchical layer, a standard deviation of the particle volume values of the adsorbent particles of each of the hierarchical layers being less than 20%, preferably less than 5% relative to the average particle volume of the adsorbent particles constituting the hierarchical

Abstract: A composite adsorbent mixture is provided, including at least one adsorbent active principle in the form of microparticles and a non-adsorbent thermal principle in the form of microparticles, where the characteristic mean size Di of the microparticles of the thermal principle is smaller than the characteristic mean size Da of the microparticles of the active principle.

Abstract: Agglomerate comprising a first phase change material (PCM) and a constituent having a density greater than 800 kg/m3 and forming the core of said agglomerate.

Abstract: PCM particle consisting of an agglomerate comprising a phase change material (PCM) and a coating layer with a composition different from that of the agglomerate.

Abstract: A thermocyclic process having a short cycle time, typically a cycle time of less 30 minutes, especially a PSA (Pressure Swing Adsorption) process, using agglomerates that contain phase change materials (PCMs), so as to reduce the thermal effects that said thermocyclic process is subjected to during each cycle is provide.

Abstract: The present invention relates to a process for manufacturing an agglomerate in the form of beads made up of microcapsules of a phase change material, the process comprising wet-granulation and fluidized-bed drying.

Abstract: A process for gas purification or separation intended to produce a gas mixture containing mainly hydrogen and, to a minor extent CO, it being imperative for the CO content to remain below a set value is presented. This invention particularly relates to adsorption processes and even more particularly to processes of the PSA (“Pressure Swing Adsorption”) type.
