Introduction to properties, advantages and applications of activated alumina

Activated alumina is a kind of white spherical porous particles with uniform particle size, smooth surface, high mechanical strength, strong dilution force, odorless, insoluble in water, ethanol, water absorption, non-cracking, unchanged and renewable.

Activated alumina has many good properties, such as good adsorption performance, porous catalytic activity and high dispersion. The use of alumina in catalysts is often referred to as "active alumina". It is a porous, highly dispersed solid material with large surface area. Its microporous surface has the characteristics required for catalysis, such as adsorption performance, surface activity, good thermal stability, etc., so it is widely used in the catalyst and catalyst carrier of chemical reaction.

Activated alumina balls are divided into γ Type and χ-ρ Type, which can be divided into activated alumina ball adsorbent, activated alumina ball desiccant and activated alumina ball catalyst carrier. Main uses: high performance activated alumina can improve the density, fluidity and strength of activated alumina, increase the output of secondary mullite, reduce water addition and reduce porosity.

In addition, active research alumina can also be used as a desiccant, with large water absorption capacity, fast drying speed and regeneration (400-500K baking).

Introduction to properties, advantages and applications of activated alumina

Advantages of activated alumina

Activated alumina is made of high-purity alumina through scientific blending and catalytic finishing. It has high compressive hardness and long service life, and can be reused through regeneration. Activated alumina is white, spherical, porous, tasteless, non-powdery and insoluble in water. It can absorb and remove fluorine harmful to human body in water, and can be used for decolorization of drinking water and industrial equipment sewage, deodorization of wastewater treatment, etc.

Use of activated alumina

Activated alumina can be used for drinking water treatment, tap water treatment, wastewater decolorization, wastewater treatment, circulating water treatment, chemical plant water treatment, power plant water treatment, paper plant water treatment, leather plant water treatment, printing and dyeing plant water treatment, beverage plant water treatment, pharmaceutical plant water treatment, slaughterhouse water treatment, food plant water treatment, etc. All operating enterprises need to produce sewage and wastewater, so they cannot do without boiled water treatment materials.
