What is Activated Aluminum?
Activated Aluminum is a compound made from aluminum hydroxide. It gets dehydroxylated in a certain way that produces highly porous spheres. These porous spheres can be used to perform different tasks because of its absorbent potential.
Activated Aluminum adsorbs, it’s different from other compounds that absorb other substances. When something is absorbed by an object or a substance, it does not bond with the object that absorbed it. But if something is adsorbed, it bond with the one that adsorbed it, and can only be separated with considerable heat.
For example: A sponge absorbs water, but the water can easily leak out or evaporate after some time. When a chemical is adsorbed by activated aluminum, the two will bond and only separate when heated.
Activated Aluminum Applications
Because of this useful property, activated aluminum is used to transport some gases, such as propane.
It drys the propane so it can be safely transported and there won’t be a risk of equipment corrosion.
It can also be used to clean up toxic wastes and clean rainwater.
It is an effective way to clean areas that have been contaminated by toxic substances.
When the aluminum gets in contact with those compounds, they get attached to it and don’t leak back into the environment when disposed of.
Another great and very used function is the water purification, the activated aluminum can remove fluoride, lead, arsenic and other contaminants from drinking water.
It is usually used in municipal water treatment facilities
Is activated aluminum harmful?
Activated alumina is a desiccant compound, and like most of these, it is not harmful to people or the environment. It’s the same substance as sapphire and ruby, but without the gem colors, those are given by some impurities.
If someone gets too much exposure it can be mildly irritating to skin and eyes, but this rarely happens.
There is some hypothesis saying that when using filters that contain alumina, you may get aluminum on your water.
But it isn’t true, as told before, a molecule of activated aluminum is adsorbent, and besides getting attached to other compounds (what gives it the cleaning property) it also it also doesn’t contaminate other substances.
What are Alumina Balls?
Activated Alumina ball is utilized in a variety of adsorbent & catalyst applications.
Activated Aluminum balls grade is utilized in PET Drying, Polyester Chips Drying, manufacturing methodology of peroxide. Activated Alumina Balls is also a selective adsorbent for the removal of impurities like arsenic and salt from drinkable.
This compound known as Al2O3 is responsible for drying of air, gases, and liquids.
Purification and acquisition of insulating oil and Industrial oils.
The radical low consistency, terribly high density and outstanding thermal shock resistance of Alumina Balls create an ideal environment for the regenerative burner and filtering media in the metals business.
The low level of different impurities makes this compound a wonderful recommendation for supporting adsorbents in the reaction to purify reactive monomers like olefine and propene.
What is meant by Activated Aluminum?
When we ask ourselves what is meant by Activated Alumina, we immediately think about the alumina hydroxide, which is highly porous and shows a wide surface area.
It’s also a desiccant and it is resistant to thermal shock and abrasion, therefore it will not shrink, swell, soften or have any other transformation when immersed in water.
It has a great capacity for water absorption when compared with other adsorbents, like silica gel and molecular sieve.
It is mainly used as a desiccant for warm gases including air.
What is Activated Alumina Desiccant?
Alumina Balls are a desiccant component and is widely used in industries such as chemical, fertilizer and petrochemical industry.
Can be used also in the air drying industry, in several air dryers (heated or heat lees and even compressed air ones).
They are made of aluminum oxide and can adsorb gases and liquids without changing its form, that’s why it works as a desiccant, through adsorption.
To get the reverse effect you can heat the alumina to any temperature between 350º to 600ºF.
