HYCOOL - D4.2 Set of data on currently commercially available as well as state of the art adsorber materials (RE 46)

Characterization of materials is a fundamental and powerful tool to scientifically understand them. Their microscopic and macroscopic structure and their properties are measured and analysed, so that scientists and engineers can improve materials design and application . In the case of water adsorbents for thermally driven heat pumps and chillers, the characterization allows a better understanding of their performance with respect to achievable power density and energy per cycle [1], [2]. Models to estimate such performance, and to possibly improve the design and the operation of the heat transforming device, need a good knowledge of the sorbent structure (grain and pore size, composition, atomistic structure etc.) and properties (thermal conductivity, specific heat, water capacity etc.): This report provides an overview over the measured properties of different currently commercially available and state of the art adsorption materials. In total 15 different materials were considered. The 15 materials have been selected from the 5 main classes of adsorber materials: silica gels, zeolites, activated carbons, metal-organic frameworks (MOFs) as well as composite materials. Within this report the differences of the properties relevant for sorption between and within the different materials classes are discussed: particle size, density and porosity, thermodynamic and kinetic properties, water sorption behaviour. The relevant results are summarized here whereas the full data set with the raw data for the measurements is available upon request.
