Heat storage: Hydration investigation of MgSO4/active carbon composites, from material development to domestic applications scenarios

چکیده
The scarcity of durable and low-cost sorbent materials remains a significant technological barrier to long-term heat storage. In the present work, composite based on activated carbon supports magnesium sulfate hydrates (labelled MgSO4/AC) were developed in order increase energy density improve mass transport phenomena. results characterization revealed uniform dispersion composites produced via incipient wetness impregnation. hydration enthalpy increased as MgSO4 content AC increased, reaching plateau for more than 30%wt (30-MgSO4/AC 40-MgSO4/AC samples). experiment performed 30-MgSO4/AC sample at RH = 60% verified relation between salt level enthalpy. Higher water partial pressure enhanced molecule improved hydration. showed an from 859 J/gdry material 30% 1324 60%. After 8 cycles hydration/dehydration, was practically stable. Furthermore, 30-MgSO4/AC) modeled two distinct scenarios house heating sanitary hot generation. Finally, experimentally obtained calorimetric data used implement numerical model. Two different considered, first second producing water. Both show possibility using MgSO4/AC multifunction thermochemical storage system.
