Activated alumina

The activated alumina manufactured in our factory has a large capacity of absorption, high surface area, high strength and thermal stability. It can be widely used as an absorbent, desiccant and catalyst carrier in chemical, petrochemical, fertilizer, oil and gas industries.     Technical Property of Activated Alumina                        Type  Item KA401 Absorbent KA402   Defluoridizer KA403 Absorbent for H2O­2 KA404 Antichlor KA405   Catalyst carrier KA406 Absorbent in air separation  Appearance  White ball  Main crystal phase χ-ρ χ-ρ γ χ-ρ γ χ-ρ Chemical composition  ％ Al2O3 ≥93 ≥93 ≥92 ≥90 ≥93 ≥90 Na2O ≤0.3 ≤0.3 ≤0.5   0.15-0.3 ≤0.3 I.L 6-8 6-8 ≤8 ≤ ≤5 6-8  Bulk density，g/ml 0.68-0.72 0.70-0.75 0.65-0.75 0.68-0.78 0.70-0.80 0.68-0.72  Surface area，m2/g ≥280 ≥280 200-260 ≥300 ≥200 ≥300  Pore volume，ml/g 0.3-0.45 0.3-0.42 0.4-0.46 0.3-0.5 0.4 0.3-0.5  Static absorption，％ Water 15-17 Fluorin 0.12 Water 50 Chlorine 10-20 Water 50-70 Water 17-19  Activity，％ - - 56-62 - - -  Loss on abrasion，％ ≤1.0 ≤1.0 ≤1.0 ≤0.7 ≤0.4 ≤0.8 Crushing strength，       N/grain Φ1-2 ≥40 ≥40 - ≥40 - - Φ2-3 ≥60 ≥60 - - - - Φ3-5 ≥100 - ≥100 ≥82 ≥100 ≥100 Φ4-6 ≥120 - ≥130 ≥120 ≥120 ≥110                     The products in other types or sizes can also be manufactured if to the user’s request.
