| 英文摘要 | Thermochemical energy storage (TES) is a promising technology to overcome supply-demand mismatch in the recycling of low-grade industrial waste heat. A novel sorbent is developed for low-grade TES system by employing an ordered mesoporous carbon, CMK-3, as the matrix of CaCl2 hydrates. Expanded graphite (EG) and activated carbon (AC) as matrixes are also discussed for a comparative study. All the composites show quick kinetic within 120 degrees C. Salt upload ability and heat storage capacity of the composites follow the order of CMK-3/CaCl2 (2037.2 kJ kg(-1), 50.4 wt%) > EG/CaCl2 (1637.6 kJ kg(-1), 48.1 wt%) > AC/CaCl2 (1221.8 kJ kg(-1), 46.3 wt%). CMK-3/CaCl2 show the best heat storage performance due to the ordered tubular mesostructure, which limits the deliquescence at a proper level and provided good accommodation for salt solution. The inner solution absorption presents positive thermal effect that add to total heat storage capacity, making actual heat sorption of CMK-3/CaCl2 much higher than pure chemical reaction heat. A 25-cycle sorption-desorption experiment shows excellent cycling stability of CMK-3/CaCl2. This study proves CMK-3/CaCl2 to be a promising composite for low-grade TES system below 120 degrees C, and provides new insights for improving energy density of the heat storage materials. |
