| Outline of Final Research Achievements |
Aluminum dross is a by-product discharged in an aluminum regeneration process. It is important to develop new recycling technologies for aluminum dross. We focused on porous aluminophosphates (AlPO4-n) which were one of zeolitic materials with an excellent adsorption property for water vapor. In this study, aluminum dross was applied to a raw material of AlPO4-n. The effect of hydrothermal reaction conditions on the physical properties of products was investigated. The adsorption properties for water vapor were researched to use them as adsorbents for desiccant and heat pump systems. It is possible to control the morphology of various AlPO4-n by adjusting the reaction condition. The AlPO4-5 or AlPO4-34 has larger BET surface area, and the shape of their adsorption isotherms for water vapor shows the type IV or V isotherm by IUPAC classification. It is concluded that the aluminum dross-derived AlPO4-n is suitable for a water vapor adsorbent for desiccant and heat pump processes.
