IRON-BASED WATER VAPOR ADSORBENT

摘要

PROBLEM TO BE SOLVED: To provide a water vapor adsorbent capable of adsorbing/desorbing water vapor and allowed to be regenerated at a temperature of 100°C or lower and repeatedly used.

SOLUTION: The water vapor adsorbent containing hydrous iron oxide α-FeO(OH)*iron-based layered compound containing iron and aluminum as a main component can be obtained by reacting iron material*aluminum calibration and an alkali material in a solution of a neutral to alkalescence area of pH 6-10, and the water vapor adsorbent can be desorbed/regenerated at a temperature of 100°C or less.
