Activated Alumina Pellet

Activated alumina pellet have the characteristics of stable crystal phase, large specific surface area, strong adsorption capacity, high compressive strength and low attrition rate. Their unique microstructure enables them to exhibit excellent performance in drying, adsorption, catalysis and other fields, making them an efficient and economical high-performance adsorption material.

Product Description

Activated alumina pellet are white, spherical, porous particles manufactured using modern production techniques. They feature a regular particle morphology, a well-developed pore structure, and stable chemical properties. Their exceptional adsorption capacity, mechanical strength, and thermal stability make them an ideal choice for industrial drying, water treatment, purification, and catalysis.

Activated Alumina Pellet

Product Advantages

Deep Drying and Low Dew Point: It has a strong affinity for water molecules, enabling deep drying of gases to dew points as low as -40°C or even lower.
High Strength and Long Life: Its exceptionally high crushing strength and extremely low wear rate ensure resistance to pulverization under high pressure and airflow, effectively preventing increased bed pressure drop and achieving a service life of up to 2-3 years.
Chemically Stable: It is unreactive with most gases and liquids and maintains structural stability even in high-temperature environments (up to 350°C).
Selective Adsorption: The process can be adjusted to preferentially adsorb specific substances, such as fluoride, arsenic, and phosphate, as needed.
