酸化マグネシウム水和反応の活性化

抄録

A chemical heat pump using the reaction system of magnesium oxide/water was studied as a thermal storage system by kinetic analysis. This heat pump has been rarely studied because of the low activity of MgO hydration. Therefore, an experimental analysis for activation of MgO hydration was carried out. The result shows that the activity of MgO dehydrated at low temperature (below 623K) is several times higher than that of commercial MgO. The possibility was shown that the reaction system of MgO/H₂O is applicable, and the working range of such chemical heat pumps was shown.
