The function of activated alumina

Activated alumina must be familiar to everyone. We use it in many chemical plants or households. The desiccant and adsorbent made with it are very effective and have many functions. Let me introduce the activated alumina. Function.

1. It can be widely used in deep drying of petroleum cracking gas, ethylene propylene gas and hydrogen production, drying of air separation plant, instrument air dryer, fluoride treatment in hydrogen peroxide, and can also remove sulfur gas hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons in waste gas. It is especially suitable for the defluorination treatment of fluorine-containing water.

2. At the same time, it is also determined according to the polarity of the adsorbed material. It has strong affinity for water, oxides, acetic acid, alkali, etc. It is a kind of micro-water deep desiccant and an adsorbent for adsorbing polar molecules.

3. Similar to anion exchange resin, but with high selectivity to fluoride ion, anion resin has good effect and stable capacity. Activated alumina absorbs 6400 grams of fluorine per cubic meter.

4. With many capillary channels and large surface area, it can be used as adsorbent, desiccant and catalyst.

5. It has high strength, low wear, no softening, no swelling, no pulverization, and no cracking in water.

Activated alumina belongs to the category of chemical alumina. It is mainly used for adsorbents and water purifier carriers. Due to different uses, its production methods and usage methods are also different. You can choose to be made of activated alumina according to your actual situation. reagent.
