Title:
LATENT HEAT STORAGE MATERIAL-INTEGRATED ACTIVE CARBON AND PRODUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/210386
Kind Code:
A1
Abstract:
This latent heat storage material-integrated active carbon contains an active carbon and a latent heat storage material having a microcapsule in which a phase-transition material, which absorbs and releases latent heat according to temperature, is encapsulated, wherein: in the latent heat storage material, the surface of the microcapsule is coated with an organic binder-containing layer including a thermosetting organic binder A; and the surface of the latent heat storage material is coated with an active carbon-containing layer. The latent heat storage material-integrated active carbon is an adsorbent which can prevent a heat transfer loss in voids between particles by integrating the latent heat storage material and the active carbon while suppressing damage to the latent heat storage material compared to the case of simply mixing a latent heat storage material and active carbon pellets, and which can maintain a high level of adsorption/desorption performance and durability by effectively controlling adsorption heat.
