| Popis: | For the purpose of a long-term heat storage system based on water sorption, a composite material consisting of 15 wt.% CaCl2 and zeolite Ca-X (prepared by ion-exchange with Ca2+ and subsequent impregnation with CaCl2 of a binder-free granulated zeolite Na-X) was prepared on a technical scale. In a lab-scale apparatus, the heat storage density of the composite material reaches values up to 260 kWh m-3 for water vapor partial pressures up to 33 mbar. As compared to the pure zeolites Ca-X and Na-X, this corresponds to an increase in heat storage density of 45 % and 68 %, respectively. An engineering concept based on the mechanical transport of the composite heat storage material through a pre- and a main reactor was demonstrated in a “hardware in the loop” test bench. |
