Packaging25 kg PP/HDPE bags, 150 kg steel drums or 1 MT jumbo bags
Overview
Activated alumina is a highly porous form of aluminium oxide. Its large internal surface area makes it an efficient adsorbent and desiccant: it pulls moisture, fluoride, arsenic and other contaminants out of gases and liquids, and can be regenerated with heat and reused many times.
We supply spherical beads in a range of sizes for compressed-air and gas dryers, drinking-water defluoridation units, hydrogen peroxide plants and as a carrier for catalysts.

Questions about Activated Alumina
Can activated alumina be regenerated?
Yes. Heating to about 180–300 °C drives off adsorbed moisture, so the beads can be reused for many cycles.
Which bead size should I choose?
Smaller beads adsorb faster; larger beads give lower pressure drop. Air dryers commonly use 3–5 mm; defluoridation units often use 0.5–2 mm.
What is Activated Alumina used for?
Activated Alumina is used for compressed air and gas drying, fluoride and arsenic removal from water, hydrogen peroxide production, catalyst and catalyst carrier and claus process sulphur recovery. Typical buyers are in oil, gas & petrochemicals, water treatment and chemical processing.
What are the typical specifications of Activated Alumina?
Al₂O₃: ≥ 93%; Surface area (BET): 300 – 360 m²/g; Bulk density: 0.65 – 0.80 g/cm³; Bead sizes: 1–2, 2–3, 3–5, 4–6 mm; Crush strength: ≥ 130 N per bead (3–5 mm); Static water adsorption: ≥ 18%. These are typical values; each lot ships with a certificate of analysis.
