Application: Regenerative Activated Alumina with high water adsorption capacity and strong attrition resistance to ensure less dust formation to protect downstream valves and minimize filter plugging. It is used for deep drying of gas or liquid phase of petrochemicals and drying of instruments. It  presents an exceptional cyclic stability in Thermal Swing Adsorption (TSA) applications as it minimizes hydrothermal ageing when meeting low dew point specifications. It also shows long term performance in Pressure Swing Adsorption (PSA) applications because of its very good mechanical properties. Properties: The product is a white, spherical porous material with the property of non-toxic,odorless, insoluble in water and ethanol. The particle size is a uniform, the surface is smooth, the mechanical strength is high, the ability of moisture absorption is strong and the ball is not split after absorbing water.Highly recommended for air and gas drying, where high water adsorption capacity combined with excellent mechanical properties are mandatory.
