Novel Adsorption Material for Thermal Energy Storage
Abstract
Aluminophosphate APO-tric is a novel adsorption material for thermal energy storage. APO-tric is a microporous triclinic chabazite material with ordered microporous 3-dimensional channel structure. The framework is very flexible which increases the possibility of water adsorption into the structure. During adsorption of water molecules the chabazite structure is modified. This deformation is however completely reversible and can be eliminated by dehydration at 120 ºC. The material shows a very good thermal stability up to 900 ºC and a water adsorption capacity up to 0.32 g/g.
