摘要: Abstract Progress of efficient thermal energy storage (TES) has become a key technology for the development conversion system. Among TES technologies, sorption (STES) drawn burgeoning attentions due to its advantages high density, little heat loss and flexible working modes. Based on STES, this paper presents an innovative resorption (RTES), experimental system is established investigated upgrade. 4.8 kg 3.9 kg MnCl2 CaCl2 composite sorbents are separately filled in reactor, expanded natural graphite treated with sulfuric acid (ENG-TSA) integrated as matrix transfer intensification. It indicated that highest density 662 kJ/kg 596 kJ/kg when input temperature 125 °C release 130 °C 135 °C, respectively. For different temperature, efficiency exergy range from 27.5% 40.6% 32.5% 47%, The novel RTES verifies feasibility upgrade, which shows great potential low grade utilization especially industrial process.
