Alumina filler balls are functional materials that are widely used in the chemical, petrochemical, refining, and natural gas industries. They have excellent chemical stability, high hardness and wear resistance, good thermal stability, and a large specific surface area.

The main function(alumina packing ball)

Alumina filler balls are used as support and cover materials for catalysts: In the reactor, they are used to support and cover the catalyst, buffer the impact of liquid and gas entering the reactor on the catalyst, protect the catalyst from mechanical damage, and extend the service life of the catalyst. At the same time, it can also improve the distribution of liquid and gas in the reactor, improve the efficiency and uniformity of the reaction.

Tower packing: As tower packing used in the packed tower, it increases the contact area and contact time of gas or liquid, promotes the mass transfer and heat transfer process between gas and liquid, and improves the separation and reaction effect.

In summary, alumina filler balls are a high-performance and widely used chemical filler that plays an important role in improving the efficiency and quality of chemical production processes.

Classified by alumina content(alumina packing ball)

1. Low alumina content filler balls: Alumina content is generally between 17% - 45%. These filler balls have a relatively low cost and are widely used. They need to be selected according to the use environment.

2. Medium alumina content filler balls: Alumina content is generally between 45% - 80%. These filler balls have a relatively moderate cost and are suitable for general chemical processes where the purity of alumina is not required, such as the initial drying of certain gases and the filling of simple acid-base neutralization reactions.

3. High alumina content filler balls: Alumina content can be as high as 90% - 99% or more. They have superior chemical stability, hardness, and thermal stability, and are often used in special chemical processes where high performance of filler is required, such as in the extraction of aromatic hydrocarbons in petrochemical industry and natural gas purification units.

What are the effects of alumina content on the performance of alumina-filled balls?

The specific effects of alumina content on the performance of the filler ball include the following:

1. **Compressive strength**: The higher the alumina content, the higher the compressive strength of the filler ball usually is. The higher alumina content filler ball has a more compact internal structure, with stronger bonding between particles, allowing it to withstand greater pressure without breaking or deforming.

2. **Acid-base resistance**: Alumina itself has good acid-base resistance. As the alumina content increases, the acid-base resistance of the filler ball will also increase accordingly. In strong acidic or basic working environments, the high-alumina filler ball can maintain stable chemical properties and not react chemically with acid or base, thus ensuring the service life and stability of the filler ball.

3. **Corrosion resistance**: In addition to acid-base resistance, the high alumina content filler ball also has better resistance to other organic solvents and chemicals. In some complex chemical production processes, various organic solvents and corrosive substances may be encountered, and the high-alumina filler ball can effectively resist the corrosion of these substances, ensuring the normal operation of the reactor or tower equipment.

4. **High-temperature performance**: Alumina has a high melting point and good heat resistance. The higher the alumina content, the better the high-temperature performance of the filler ball.

5. **Density**: The increase in alumina content will result in an increase in the density of the filler ball. The higher density filler ball can be more densely packed during filling, reducing the voids in the filler layer and thus improving the filling efficiency and uniformity of fluid distribution in the reactor or tower equipment. However, excessive density may also increase the load and energy consumption of the equipment, and therefore, the specific requirements of the process should be considered when choosing.

6. **Water absorption rate**: Filler balls with higher alumina content usually have lower water absorption rates. Low water absorption rate can ensure that the filler ball does not absorb excessive water or other liquids during use, avoiding performance degradation
