In this paper experimental and numerical investigations on heat transfer within a bubbling fluidized bed will be presented with respect to better heat integration in continuous temperature swing adsorption (TSA) processes for biogas upgrading. In the literature, mainly heat transfer measurements with glass or sand particles are carried out, thus special reference measurements with adsorbent 1 Conceptual process design of a CaO/Ca(OH)2 thermochemical energy storage system using fluidized bed reactors Y.A.
