Thermal energy storage with the waste-produced porous material

In conjunction with the increasing energy demand, the development of solutions for efficient use of energy and energy-saving has become very important. Recently, thermal energy storage (TES) has been frequently mentioned with the use of phase change materials (PCM) with high energy density and high latent heat content. In the thesis study, it was aimed to develop an innovative TES material with the help of paraffin-based PCM impregnated with porous materials and porous material production using municipal wastewater treatment sludge which causes environmental problems, acrylic resins and inorganic addition agents. The potentials of porosity materials and paraffin impregnated PCMs for use in the thermal energy storage process were investigated by performing proximate analysis, elemental analysis, porosity test, FTIR, Raman spectroscopy, XRD, TGA and DSC analyzes. As a result of the investigations, it has been determined that the porous materials produced have high porosity, low defect, and a high degree of graphitization and integrate with the impregnated paraffin without chemical reaction. In addition, it has been determined that the thermal energy storage capacity of Co(NO3)2·6H2O@AÇ-Paraffin PCM (76,0773 J/g) is approximately half that of pure paraffin (150,6972 J/g) and that its thermal energy storage capacity is high compared to other PCMs. This study reveals that the Co(NO3)2·6H2O@AÇ-Paraffin PCM produced within the context of the circular economy has development potential for use in TES storage applications.
