Functions of China Inert Alumina Balls

1. Catalyst Support and Protection

Inert alumina balls are installed above or below the catalyst bed inside reactors. They:

• Support the weight of the catalyst and process media

• Absorb mechanical shock from high pressure and high-velocity flow

• Prevent catalyst particles from breaking, eroding, or being carried away

This significantly extends catalyst service life and reduces operating costs.

---

2. Optimized Gas and Liquid Distribution

The uniform spherical shape creates stable and evenly distributed flow channels, allowing gases and liquids to pass through the catalyst bed evenly.
This prevents channeling and bypass flow, improves mass and heat transfer, and increases reaction conversion efficiency.

---

3. Thermal Insulation and Flame Arresting

High-alumina inert alumina balls offer excellent high-temperature resistance and can act as a thermal insulation layer inside reactors.
In petrochemical systems, they also function as flame-arresting media, preventing flame propagation and improving process safety.

4. Packing and Filtration Support

In distillation columns, absorption towers, and separation equipment, inert alumina balls can be used as:

• Inert packing media

• Filtration support to trap fine impurities

This helps prevent clogging and ensures smooth equipment operation.
