Activated Alumina Balls

Activated Alumina Balls

Zibo Xiangrun and Shandong Bairui supply excellent activated alumina balls. Activated Alumina balls are comprised of aluminum oxide (A12O3) in a smooth spherical form with high crush strength. It is highly porous and a high surface area greater than 320 m2/g. It is an excellent desiccant for liquids and gases, and can achieve dew points from -40°F (-40°C) depending on the operating conditions and the design of the dryer. Activated Alumina will adsorb many molecules to some degree, but will preferentially adsorb the molecules with the highest polarity. Activated Alumina is resistant to thermal shock and abrasion and will not shrink, swell, soften nor disintegrate when immersed in water.

The size of activated alumina Xiangrun supply:
 Xiangrun supply Activated Alumina in three  different sizes of beads: 1/8" (3‐5 mm), 3/16" (4‐6 mm) ,1/4" (6-8 mm), 5-7mm. 1-2mm, 2-3mm, 3-4mm, 4-5mm, 6-7mm,  8-10mm, 10-12mm, 12-14mm.
 For microspheres, like 40*80 mesh,  45*85mesh, 0.5-1mm are Xiangrun’s activated alumina.

Typical applications for activated alumina are used in:

●Activated alumina for compressed air dryers

●water purification to remove fluoride, arsenic and selenium

●removal of degradation acids from transformer oils, lubricating oils, and  refrigerants

●natural gas drying

●liquefied natural gas drying

●activated alumina for air Filtration

●Adsorption

●Desiccant

●Purification of Process Liquids and Gases

●pH Balance


Typical Properties of activated alumina balls:

●Large Specific Surface Area

●High Pore Volume

●Defined Pore Size Distribution

●Specific Catalytic Reactivity

●Specific Adsorptive Capacity

●High Crushing Strength


The Regeneration of activated alumina balls
Activated Alumina  can regenerate to its original adsorption efficiency by heating the desiccant to any temperature from 350° to 600°F (177° to 316°C). When the Activated  Alumina desiccant is heated as described above, the water stored in it is  released, which enables the Activated Alumina filters to be reused over and  over again.

Deliver, packing,  Shipping and Serving of the activated alumina:

●2-7 working days since payment receipt

●25kg/plastic bag, 150kg/new steel drum, 25kg/paper drum, 500kg/750kg/jumbo bag. The all  could add wooden pallets, non-fumigation pallets and plastic pallets as your  requirement.
