Product Description

Actived Alumina CAS:1344-28-1

Activated Alumina balls are white spherical porous particles with average particle size, smooth surface, high mechanical strength, strong hygroscopicity, do not swell or crack after absorbing water, and remain intact, non-toxic, odorless, and insoluble in water. Under certain operating conditions and regeneration conditions, the drying depth of activated alumina is as high as -70 degrees below the dew point temperature.

In the petrochemical and Fertilizer industries, it is widely used as a catalyst and catalyst carrier. Activated alumina also has adsorption characteristics, so it is used as a desiccant for gas and liquid, an adsorbent for gas purification, a defluorinating agent for drinking water, and a color and odor elimination agent for industrial sewage.

The following also explains the physical properties of activated alumina balls:

1. The angle of repose. The angle of repose of alumina refers to the inclination angle of the natural accumulation of materials on a smooth surface. Alumina with a larger angle of repose is easier to dissolve in the electrolyte, and can be well covered on the electrolyte crust during the electrolysis process, and the flying loss is also small.

2. The content of a-Al2O3. The content of a-Al2O3 in alumina reflects the degree of calcination of alumina. The higher the degree of calcination, the higher the content of a-Al2O3, and the hygroscopicity of alumina becomes worse as the content of a-Al2O3 increases. Therefore, the alumina used for electrolysis requires a certain amount of a-Al2O3. But the solubility of a-Al2O3 in the electrolyte is worse than that of Υ-Al203.

3. Bulk density. The bulk density of alumina refers to the weight of the material per unit volume in its natural state. Generally, alumina with a small bulk density facilitates dissolution in the electrolyte.

4. Granularity. The particle size of alumina refers to its thickness. The particle size of alumina must be appropriate, too coarse to dissolve in the electrolyte slowly, or even precipitate; too small to easily fly and lose.

5. Specific surface area. The specific surface area of alumina refers to the total surface area of the sum of the external surface area and the internal pore surface area per unit weight of the material. It is an important indicator of the activity of a substance. Alumina with a large specific surface area has good solubility in the electrolyte, high activity, but easy to absorb moisture.

6. Wear coefficient. The so-called wear coefficient is the percentage change in the particle size content of the sample after alumina is collided on a fluidized bed under controlled conditions. The wear coefficient is a physical index that characterizes the strength of alumina.


Application

It can be used in a wide range of fields. In addition to water removal, it can also be used in the adsorption of air impurities, high-level gas purification processes, or desulfurization in petroleum products. It is also commonly used as a carrier in column chromatography.

Factors affecting adsorption performance:
(1) Particle size: The smaller the particle size, the higher the adsorption capacity, but the smaller the particle size, the lower the particle strength, which affects its service life.
(2) Raw water pH value: When the pH value is greater than 5, the lower the pH value, the higher the adsorption capacity of activated alumina.
(3) Initial fluorine concentration in raw water: the higher the initial fluorine concentration, the larger the adsorption capacity.
(4) Alkalinity of raw water: The high concentration of bicarbonate in raw water will reduce the adsorption capacity.
(5) Chloride ion and sulfate ion.
(6) The influence of arsenic: activated alumina has an adsorption effect on arsenic in water. The accumulation of arsenic on activated alumina causes a decrease in the adsorption capacity of fluoride ions and makes it difficult to elute arsenic ions during regeneration.
