What are Activated Alumina Balls?


Activated Alumina BallsActivated Alumina Balls are a commonly used desiccant. They are in demand mainly for two reasons- large surface area and high absorption qualities. Other properties of Activated Alumina Balls, which add to its popularity are 1) its insolubility in water 2) easily dissolving in acids and alkalies. Both these properties make it the best desiccant for absorbing toxins and harmful substances from the surroundings.


Main Features of Activated Alumina Balls


Activated Alumina Balls have many distinct features. Some of the main ones are listed below:


1) Highly recommended for removing moisture from gases.

2) High degrees of porosity and more surface area.

3) Best suited for compressed air drying systems.

4) Remains physically and chemically intact during high temperatures.

5) Can remove many fluoride molecules from drinking water.


Different Uses of Activated Alumina Balls

Air Drying Desiccants

Activated Alumina Balls have uses across various industries. These include water purification, thermal swing adsorption process, oil filtration, air and gas drying, heated and heat less drying process. Among all the uses, the main use of Activated Alumina balls is in purification of drinking water. In this process, the Activated Alumina balls are first placed in the water that has to be purified. As the pH and alkaline levels of the water is low, more fluoride molecules will be attracted to the Activated Alumina desiccant. In this way, the water meant for drinking and household purposes is purified and freed from impurities and harmful substances.


The biggest advantage of using Activated Alumina balls in water purification is that as the desiccant has numerous pores, it can attract more fluoride molecules over a larger surface area. This translates into more impurities being taken in over more areas. The water meant for purification usually contains 2ppm (parts per million) fluoride levels before filtration. This water is then passed through Activated Alumina filters. After purification, the water is found to contain fluoride levels less than .1ppm. This shows how effective Activated Alumina balls are as a desiccant.

In spite of having so many gas drying desiccants out there in the market, there has a strong significance why people (those who need to use these desiccants) are fond of activated alumina when it comes to dry out a warm gas appropriately. One of the prime reasons is that these balls are formulated with aluminum oxide which is highly porous and possess a tremendous surface area which let them soak up the gas and water molecules on a large scale. The surface normally ranges from 345-415 square meter/gm and this wide surface makes this element adsorb more gas, moisture, water vapor and humidity, even more than silica gel as well. For having such a higher capacity of gas consumption at an elevated temperature as well, it is an obvious choice for the various industrial purposes like; purification, isolations etc.

The alumina has a resistant power from thermal shock and abrasion, more so, they don’t get shrink, swell, soften and not even they disintegrate when completely saturated into gas. The element is formulated with aluminum hydroxide and the process is called dehydroxylation. Successful accomplishment of the process results in production of highly porous material with a huge surface area. It is made of aluminum oxide (Al2O3) and exhibits a high surface area compare to its weight and because of these, it has lots of small pores which run throughout it.


This Gas drying activated alumina is generally used for warm gases like hydrogen sulphide, sulfur oxide etc. including air as well because it has higher water absorption capacity even at a high temperature. This chemical substance doesn’t make so much of physical changes after getting immersed into gas molecules. Despite being used as an adsorbent, the activated form of alumina also possess catalyst applications in the form of alumina balls which includes the absorption of catalyst in the production of polyethylene. The utilization of activated alumina AD101 ranges from the purification (mainly removing metallic traces, TBC and HF compounds) of gases and liquids, drying out organic liquids such as LPG, propylene, butane etc.


The desiccation of gases includes steam cracked gases, catalytic reforming gases, synthesis gases, methyl chloride and natural gases etc. and it also dry out oxygen, nitrogen, hydrogen, CO2. The most enchanting fact is that this form of alumina can be regenerated when it is entirely drenched with gas molecules by heating up the alumina at around 2000C as it releases the gas molecules at then.
