Activated alumina porous granular. For gas, water vapor, and some of the H&X china silicon carbide water has selective adsorption ability, and can be used as a catalyst and catalyst carrier and carrier of chromatographic analysis.
character
Porous granular.
use
For gas, water vapor, and some of the liquid water has selective adsorption ability. After the adsorption saturation can be in about 175-315 ℃ heating to remove water and resurrection. Adsorption and H&X calcium metal granules for many times. In addition to the used as a desiccant, but also from the pollution of the oxygen, hydrogen, carbon dioxide adsorption oil steam, gas, etc. And can be used as a catalyst and catalyst carrier and carrier of chromatographic analysis.
Preparation or source
Controlled by the temperature heating aluminum hydroxide to remove moisture.
