Preparation and thermal storage performance of novel composite sorbent with activated alumina matrix
CIESC Journal,2020,Vol 71,No. 07
A new type of composite sorbent based on activated alumina (AA) and CaCl 2 as a hygroscopic salt was developed. It can be used in thermochemical adsorption heat storage systems with water as the sorbent, and its internal structure, adsorption performance and heat storage performance were studied. The samples with different salt content were fabricated to store low-temperature thermal heat by impregnation methods. The morphologies records, sorption kinetics and thermal energy storage performance of AA/CaCl 2 composite sorbents were investigated. The maximum salt content of the solution leakage phenomenon was determined. Sorption kinetics and equilibrium sorption capacity under conditions of 30 °C and multiple relative humidity were studied by utilizing a constant temperature and humidity chamber. The influences of salt content and relative humidity on the sorption performance of AA/CaCl 2 composite sorbent were studied. Results showed the sorption capacity of AA/CaCl 2 composite sorbent increased with increasing salt content and relative humidity. The specific surface area and pore volume were measured by an automatic specific surface area and porosity analyzer. The energy storage density was measured by a simultaneous thermal analyzer. The sample with the highest salt content had the best energy storage performance with 0.51 kW·h/kg mass energy storage density and 610.2 kW·h/m 3 volumetric energy storage density. As a consequence, AA/CaCl 2 composite sorbent is a promising sorbent in the field of chemisorption thermal energy storage.
