Résumé

It was demonstrated that chemical heat storage materials mixed with metal hydroxides were capable of storing heat at medium temperatures of approximately 200-300°C. The performances of the developed materials were demonstrated in a thermo-balance and packed bed reactor. The mixed hydroxides can increase the operation heat storage temperature by changing the composition of mixed metal oxides in the material. Mg(a)Ni(1-a)[OH)2, which is a mixed hydroxide of magnesium hydroxide, Mg(OH)2, and nickel hydroxide, Ni(OH)2, is a candidate heat storage material. The mixed hydroxide was dehydrated, that is, it was capable of storing heats at 200-300°C, at which pure Mg(OH)2 could not be dehydrated and could not store heat. The heat output performance of the material was examined in a packed bed reactor. It was shown that the mixed hydroxide material was potentially useful for chemically storing medium-temperature heat such as waste heats emitted from internal combustion engines, solar energy system and high-temperature processes.
