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. Item Model Al2O3 % Chemical name Size mm Bulk density g/cm2 Surface area m2/g Pore valume ml/g Water adsorption % Wear ratio % Crushing strength N/pc Activated Alumina Desiccant WHA***1 ≥*3.5 α-β Φ**5 ≥0.*5 ≥**0 ≥0.*8 ≥*9 ≤0.4 ≥*0 Φ**6 ≥0.*2 ≥**0 ≥0.*8 ≥*9 ≤0.4 ≥**0 Φ**8 ≥0.*2 ≥**0 ≥0.*8 ≥*9 ≤0.4 ≥**0 Φ**7 ≥0.*2 ≥**0 ≥0.*8 ≥*9 ≤0.4 ≥**0 WHA***2 ≥*3.5 α-β Φ**6 ≥0.*5 ≥**0 ≥0.*0 ≥*0 ≤0.6 ≥*0 Φ**7 ≥0.*2 ≥**0 ≥0.*0 ≥*9 ≤0.6 ≥**0 Activated Alumina Defluoridizer WHA***4 ≥*2 α-β Φ**3 ≥0.*4 ≥**0 ≥0.*8 ≥*0 ≤0.4 ≥*5 Φ**2.5 ≥0.*4 ≥**0 ≥0.*8 ≥*9 ≤0.4 ≥*8 Φ0.**2 ≥0.*4 ≥**0 ≥0.*8 ≥*9 ≤0.4 ≥*0 Sulfur Recovery Catalyst WHA***1 ≥*2 α-β Φ**6 ≥0.*0 ≥**0 0.**0.5 ≥*0 ≤0.*5 **5
