Abstract
Complex of hydroxyl-aluminum-silicate and low crystalline clay (HAS-Clay) and precursor of HAS-Clay were developed as adsorbents for desiccant air-conditioning system. The water vapor adsorption isotherms of HAS-Clay and precursor of HAS-Clay were linear shaped. Both HAS-Clay and precursor of HAS-Clay had micro-pores about 0.6 nm in diameter and meso-pores of two different sizes. Although the heatproof temperature of HAS-Clay was higher than 300°C, the heatproof temperature of precursor of HAS-Clay did not become clear because of amorphous material. The amount of water vapor of HAS-Clay were 33.7, 38.2 and 41.8 wt% in the dehydration temperature of 60, 80 and 100°C, respectively. And the amount of water vapor of precursor of HAS-Clay were 24.4, 28.5 and 29.9 wt% in the dehydration temperature of 60, 80 and 100°C, respectively. So HAS-Clay and precursor of HAS-Clay were adsorbents which were excellent in low-temperature dehydration (regeneration) and were suitable for desiccant air-conditioning system.
