WATER VAPOR SORPTION-DESORPTION HEAT-ACCUMULATION MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a water vapor sorption-desorption heat-accumulation material capable of accumulating waste heat of about 200°C in high density without causing the problem of corrosion and deliquescence.;SOLUTION: The water vapor sorption-desorption heat-accumulation material is composed of a porous alumina supporting an alkali metal or alkaline earth metal halide in an amount of 1-50 mass% based on the porous alumina. Preferably, the alkali metal is lithium, the alkaline earth metal is calcium and the halide is chloride. The porous alumina is preferably mesoporous alumina.;COPYRIGHT: (C)2007,JPO&INPIT
