Activated alumina is a highly engineered form of aluminum oxide (Al2O3) known for its exceptional surface properties. Ningbo Inno Pharmchem Co., Ltd. is a leading provider of this essential material, recognizing its broad utility in chemical processing. Understanding its core characteristics unlocks its potential in numerous industrial applications.

The defining feature of activated alumina is its extensive internal pore structure, which results in a very large specific surface area, typically ranging from 300 to over 350 m²/g. This high surface area, combined with the material's polar nature, makes it an excellent adsorbent and desiccant. It has a strong affinity for polar molecules, particularly water. This characteristic is exploited in applications requiring deep drying of gases and liquids, such as in the purification of ethylene, propylene, and hydrogen.

As a desiccant, activated alumina is highly effective in removing trace amounts of moisture. It is widely used for the drying of instrument air, ensuring the reliability of pneumatic systems and sensitive equipment. In the context of gas processing, it plays a crucial role in the deep drying of cracked gas streams, which are often saturated with water vapor. Its ability to achieve very low dew points makes it indispensable where high purity is critical.

Furthermore, activated alumina is utilized as a defluorinating agent, particularly in the treatment of drinking water. It selectively adsorbs fluoride ions, helping to reduce their concentration to safe levels, thereby protecting public health. This application underscores its importance in environmental protection and water resource management.

The material's robustness is another significant advantage. Activated alumina exhibits high mechanical strength, good crush resistance, and low abrasion loss. This ensures its structural integrity during handling, loading into vessels, and operation, even under conditions of high pressure and flow. It does not soften, expand, or become powdery when wet, which is a common issue with other drying agents.

In catalytic applications, activated alumina serves as an excellent catalyst carrier. Its high surface area provides an ideal platform for supporting active catalytic metals or compounds. Its thermal stability and chemical inertness allow it to function effectively in a wide range of reaction environments. Ningbo Inno Pharmchem Co., Ltd. offers activated alumina in various particle sizes and specifications, catering to the diverse needs of the chemical industry, from adsorption processes to advanced catalytic systems.
