activated  alumina ceramic balls has many capillary tao white chondrules, there are a lot of wool stoma channel, these duct surface has higher activity, can for gas, steam, liquid water has selective adsorption ability. Under certain conditions dry depth can reach - 70 ℃ below, saturated in the dew point ℃ 175-400 ℃ heating except water and resurrection, can carry on the multiple, but also from the stain of oxygen and hydrogen and sulfur dioxide of adsorption lubricating oil and other oil steam, and can do catalyst or carrier. Widely used in petrochemical and refining, electronics, ethylene, propylene, air drying plant in the country has many hydrogen peroxide factory, chemical fertilizer plants, oxygen plant oil refining and petrochemical units using, and achieved good results. According to the activated alumina ceramic balls adsorbed substance the polarity of the strength to determine, on water, oxide, acetic acid, alkali etc. Has strong affinity, is a kind of micro water depth, also desiccant molecular absorbent adsorption polarity.
