一般注記"With regard to chemical heat storage materials applicable to solid base metal compounds, a manufacturing concept has been shown for a new porous solid supported chemical heat storage material (PSM) which can maintain high reactivity and cope with volume changes. The pore structure characteristics of a carbonaceous porous solid supported Ca(OH)2 chemical heat storage material (Ca(OH)z-PSM) prepared based on this concept was evaluated, and as a result, it was found that the Ca(OH)2-PSM can be made into a high-density heat storage material with a maximum CaO/C weight ratio of 2.18, and the Ca(OH)2 is supported through thin layer dispersal primarily in pores of diameter O.15μm and 30μm in the unsupported carbonaceous porous solid. An evaluation of reactivity was conducted on a sample of this material, using the exothermic characteristics in repeated heat storage and release as an indicator, and an evaluation of long-term stability in form was conducted based on optical observation of the sample after repeated heat storage and release. In evaluation of exothermic characteristics, the heat production temperature was measured in a hydration reaction, under saturated steam conditions at 60°C, using a packed-bed reactor simulating a chemical heat storage/chemical heat pump. The results showed that with Ca(OH)2-PSM, the maximum temperature rise is maintained even with 15 repetitions. This is because agglomeration inhibition was controlled due to support of Ca(OH)2 in pores through thin layer dispersal. In addition, the results of optical observation showed that, even after repeated hydration/dehydration reactions, both the shape of the heat storage material particles and the Ca(OH)2 support state are maintained in their original condition, and that secondary reactions do not occur. Thus it is evident that Ca(OH)2-PSM functions as a high-performance heat storage material for CHP."
