1. Product description of activated alumina ball adsorbent
The product has high strength, good physical properties, non-toxic and tasteless. When immersed in water, it will not soften, expand or crack. It has long service life and is easy to regenerate. The product is mainly used as air compressor adsorption desiccant, drinking water or defluorination agent of industrial equipment. It has strong deaeration capacity. It is widely used as catalyst and catalyst carrier in petrochemical and chemical fertilizer industry. It is a porous white sphere with high dispersion. The main crystal forms are y-al2o3 and ρ- There are two kinds of Al2O3. Y-al2o3 has a large specific surface area, about 200-600m2 / g, and has strong adsorption capacity and catalytic activity. Its pore structure has the characteristics required by catalysis, such as adsorption performance, surface activity and stability. It is not powdered when soaked in water in the medium.
