The main function of activated alumina

Activated alumina belongs to the category of chemical alumina and is mainly used for adsorbents, water purifiers, catalysts and catalyst carriers. Activated alumina has selective adsorption capacity for gas, water vapor and moisture in some liquids. After the adsorption is saturated, it can be heated at about 175-315 ℃ to remove water and resurrect. Adsorption and resurrection can be performed multiple times. In addition to being used as a desiccant, it can also absorb the vapor of lubricating oil from polluted oxygen, hydrogen, carbon dioxide, natural gas, etc. And can be used as catalyst and catalyst carrier and chromatographic analysis carrier. It can be used as a defluorination agent for high-fluoride drinking water (large defluorination capacity), a defluorination agent for circulating alkanes in the production of alkyl benzene, a deacidification and regenerating agent for transformer oil, and as a gas drying agent in the oxygen production industry, textile industry, and electronic industry. , automatic instrument air drying and as desiccant and purifying agent in chemical fertilizer, petrochemical drying and other industries (dew point can reach -40 ℃), and pressure swing adsorption dew point can reach -55 ℃ in air separation industry. It is a highly efficient desiccant for deep drying of trace water. Ideal for heatless regeneration units.
