Adsorbents for dehumidification and heat storage
The principle of adsorption is used in many technical applications, for instance to dehumidify air or gases or to separate mixtures of materials. A further application is sorptive thermal storage, which can be used to increase energy efficiency in industrial processes and thermal technology applications. Due to ease of handling and manufacture, pelleted adsorbents (e.g. zeolites, activated carbon, silica gel etc.) in spherical or cylindrical forms are generally used. However, these often have restricted mechanical stability and extremely limited thermal conductivity. This is a disadvantage for the performance of many applications and thermal storage in particular.
