Activated alumina ball is a kind of white spherical porous particle, particle size uniform, smooth surface, mechanical strength, moisture absorption, water absorption after expanding crack remains intact, non-toxic, odorless, insoluble in water, ethanol. It has many capillaries, larger than surface area, which can be used as adsorbent, desiccant and catalyst. Also according to the polarity of the adsorption material strength, the oxide, water, acetic acid, alkali and other strong affinity, is a kind of micro water depth of desiccant, also adsorbent adsorption polar molecules.
In temperature county, the active alumina is similar to the anion-exchange resin, but the selective anion resin of fluorine ion is large. The active alumina adsorption defluorine is good, the capacity is stable. This product is of high strength, low wear and low water impregnation, no expansion, no powder, no breakage. Can be widely used in petroleum cracking gas, the depth of the dry ethylene propylene gas and hydrogen production, dry air separation device, instrument air drying machine, hydrogen peroxide solution of hydrogen fluoride treatment can remove the sulfur in the exhaust gas, sulfur dioxide, hydrogen fluoride, hydrocarbon and other pollutants, especially for fluoride water fluoride in processing.
The active alumina balls can be divided into three levels based on different alumina levels:
60% - 65 percent alumina,
2, 75% - 80% alumina content is a medium-high alumina ball,
More than 90 percent of alumina is high in aluminum. The high aluminum ball is divided into 90 porcelain, 92 porcelain and 95 porcelain.
