Activated Alumina Balls
Molecular Formula: Al2O3 • nH2O (0<N≤0.8)
Activated alumina has much micro-paths, so the specific surface is large. It can be used as absorbent desiccant and catalyst carrier. It is also a kind of trace water desiccant and the pole-molecular absorbent, according to the absorbed molecular polarization, the attachment force is strong for water, oxide, acetic acid, alkali etc.
This product is used for deep drying of gas or liquid phase of petrochemicals and adsorption drying by automatic instruments.
