Activated Alumina Balls 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.
Activated Alumina ball is comprised of a synthetically-produced aluminum oxide (A12O3) in a smooth spherical form with high-crush strength. It is highly porous and can have a high surface area greater than 300m2/g. It is an excellent desiccant for liquids and gases, and can achieve dew points from -40°C depending on the operating conditions and the design of the dryer. It will adsorb many molecules to some degree, but will preferentially adsorb the molecules with the highest polarity. Why Choose Activated Alumina for Air Drying?
Activated Alumina ball works as a desiccant through adsorption, so as air passes through the desiccant beads, the water in the air sticks to it and becomes trapped, enabling the air that passes through the activated alumina filter to become dried out. Even if immersed in a liquid, the beads will not fall apart or soften.
Activated Alumina balls can be restored to its original adsorption efficiency by heating the desiccant to any temperature from 177° to 316°C. When the 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.

Applications of Activated Alumina Balls
• Catalyst for recovering sulfur in the petrochemical industry
• Excellent defluorination agent for drinking water and for recycling alkyl-hydrocarbon in alkylbenzene production
• Reclaiming agent for de-acidic in transformer oil, and de-arsenic agent in the Acid industry
• Catalyst for polyhydro-ammonia by substituting silica gel with ball-shaped product
• Desiccator and purifying agent.
Activated Alumina ball is extremely effective for drying gases and is very stable physically and chemically, even in high temperature and corrosive environment. It is widely used for compressed air dryers, because of its cost effectiveness in relation to the other types of desiccants. With its high surface area, high moisture capacity, and high crush strength, the desiccant beads can easily withstand the saturated conditions that are found within an air compressor.
