Industrial Materials

Alumina

Thanks to its porous structure and large specific surface area, activated alumina can physically adsorb water vapor from various gases (commonly used for deep drying) and selectively adsorb certain acidic or polar gas molecules.

In the chemical industry, specially treated γ-alumina is widely used as a catalyst support. Its surface properties allow highly dispersed and stable loading of active metal components such as platinum and palladium, which greatly improves catalytic efficiency and reaction rate in gas‑related processes including automotive exhaust purification, petroleum hydrofining, and olefin production from alcohol dehydration.
