In the catalyst industry, alumina (Al₂O₃) is specifically termed "activated alumina support." This porous, highly dispersed solid material possesses a large surface area, with microporous surfaces exhibiting catalytic properties. The support is available in various shapes (e.g., strips, cylinders, cloverleaf) and can be customized per user specifications.
Such as adsorption performance, fluoride removal performance, drying performance, surface activity, excellent thermal stability, etc., so it is widely used in catalysts and catalyst carriers for chemical reactions.
Alumina support refers to white powdered or formed alumina solids, which is a widely used class of catalyst supports, accounting for about 70% of industrial supported catalysts. Alumina has a variety of forms, not only different forms have different properties, but even the same form has different properties due to its different sources, such as density, pore structure, specific surface area, etc.
Activated alumina is a porous, highly dispersed solid material, with a large surface area, its microporous surface has the characteristics required by catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc., with high strength, low wear, water immersion does not soften, no expansion, no pulverization and other characteristics, so it is widely used as a catalyst and catalyst carrier for chemical reactions.
