Preparation, Hydrothermal Stability, and Storage Properties of Binderless Zeolite Beads in Open and Closed Thermochemical Storage Systems

摘要：

Novel binderless zeolite beads of the type A and X have been synthesized following a new approach of manufacturing. The new products have been characterized by electron microscopy (SEM), mercury intrusion, nitrogen adsorption, thermogravimetry (TG), water adsorption isotherm measurements, cyclic hydrothermal treatments under close to open and closed storage conditions, and storage tests. The lab-scaled thermochemical storages have embraced 1.5 L storage material. The binderless molecular sieves show an improved adsorption capacity and kinetics, sufficient hydrothermal stability, higher specific energies, and the potential for a better performance density of the storage. Both open and closed storage tests have shown comparable adsorption capacities and specific energies for the binderless molecular sieves. A significant higher discharging temperature, however, could be realized with the open storage system.
