Description
Activated Aluminium Oxide Properties
What is Activated Aluminium Oxide ?
Activated alumina is a porous, highly dispersed white powder with a high specific surface area, porosity, and adsorption properties. It has the following properties:
Physical property
Activated alumina has a high specific surface area and a developed pore structure. Its appearance is a white or off-white powder, uniform particle size, smooth surface, insoluble in water, acid, alkali solutions, and organic solvents. The specific surface area of activated alumina is usually between 200-400m²/g, the pore volume is 0.7-1.5ml/g, and the pore size is 10-15 angle. It also has high hygroscopicity, with a hygroscopicity of up to 25%.
Chemical property
Activated alumina has good thermal stability and can be used at high temperatures. It can be reduced and oxidized at different temperatures, showing different chemical properties. At high temperatures, activated alumina has good caking resistance and can maintain stable physical and chemical properties.
Adsorption property
Activated alumina has strong adsorption properties and can absorb gases, liquids, and organic substances. It has a large adsorption capacity, fast adsorption speed, and good chemical stability, and can be used to separate and purify many substances.
Mechanical property
The Activated Alumina has good mechanical strength and wear resistance and is difficult to wear or break. Its high hardness can resist the damage of external mechanical action.
Chemical reactivity
The activated alumina has a high chemical reactivity and can be used as a catalyst or a carrier in various types of chemical reactions. It can be used in hydrocarbon cracking and hydrogenation reactions, alkylation reactions, isomerization reactions, and hydrogenation reactions in the petrochemical industry. ​​​

Applications of Activated Aluminium Oxide :
Oil and gas processing
Active molecular sieves are widely used in oil and natural gas processing. They can be used as catalysts for hydrocarbon cracking and hydrogenation to improve the quality and purity of petroleum products. In addition, an active molecular sieve can also be used as a catalyst carrier for various petrochemical reactions, such as alkylation reaction, isomerization reaction, hydrogenation reaction, and so on. At the same time, the active molecular sieve can also be used for natural gas conversion and separation to improve natural gas utilization rate and purity.
Environmental protection
Active molecular sieves are also widely used in the field of environmental protection. It's a method to remove harmful VOCs and gases (volatile organic compounds) from the air, protecting the environment and human health. In addition, active molecular sieves can also be used in water treatment, desulfurization denitrification, and other fields to remove harmful substances and gases in water bodies. These applications not only help protect the environment but also help improve the quality of human life.
Chemical reaction catalysis
Active molecular sieve exhibits excellent chemical reactivity and is catalysts for various chemical reactions, such as hydrocarbon cracking, alkylation, isomerization, hydrogenation, etc. Because of its high surface area and well-developed pore structure, the catalytic performance of active molecular sieves is often better than that of traditional catalysts. In addition, the active molecular sieve can also be used as a catalyst carrier, in combination with other metal catalysts, to improve catalytic performance and selectivity.
Gas storage and separation
Active molecular sieves with high specific surface area and developed pore structure can be used for gas adsorption and separation. Because the active molecular sieve has good chemical and thermal stability, it can be adsorbed and separated under different temperature and pressure conditions. In addition, the active molecular sieve can also be used for gas drying and purification, providing high-purity gas raw materials.
Biomedical application
Active molecular sieves have good biocompatibility and chemical stability and can be used in the biomedical field. For example, active molecular sieves can be drug carriers in drug delivery systems to improve efficacy and reduce side effects. In addition, active molecular sieves can also be used for applications such as bioimaging and sensing, providing new tools and methods for biomedical research.

Production Method of Activated Aluminium Oxide :
Purification of natural molecular sieve
Natural molecular sieves are extracted from natural minerals or volcanic ash, and active molecular sieves can be obtained after purification and processing. The benefit of this method is that raw materials are straightforward to find, the production cost is low, but the purification and processing process is more complex.
Hydrothermal synthesis
The hydrothermal synthesis method is to dissolve sodium silicate, sodium aluminate, and other raw materials in water under high temperature and high-pressure conditions and then through crystallization, drying, and other steps to prepare. The advantages of this method are a simple preparation process, low cost, and high purity molecular sieve can be obtained.
Ion exchange method
The ion exchange method exchanges raw materials such as sodium silicate or aluminate with specific ions to produce molecular sieves with specific structures. The advantage of this method is that high purity and high activity molecular sieves can be obtained, but the production cost is high, and more ion exchangers need to be used.
The gas phase synthesis method
The gas phase synthesis method generates a molecular sieve by gas phase reaction of raw material under high temperature and pressure. The advantage of this method is that molecular sieves with high activity and stability can be directly synthesized. Still, special gas raw materials and equipment need to be used, and the production cost is high.
Template synthesis
Template synthesis is the hydrothermal synthesis or chemical reaction of raw materials such as sodium silicate or sodium aluminate in the presence of a specific template agent to generate molecular sieves with specific structures and properties. The advantage of this method is that high purity and highly ordered molecular sieve can be obtained. Still, the production cost is high because specific template agents and strict control of reaction conditions are required.
