Characteristics of activated alumina

In rush bai agent used in alumina du is usually referred to as "activated alumina, it is a kind of porous, high dispersion of solid materials, there is a lot of surface area, its microporous surface qualifications for the catalysis properties, such as adsorption, surface activity, good thermal stability, etc., so is widely used as a chemical reaction catalyst and catalyst carrier.

Activated alumina has the ability of selective adsorption to gas, water BAI vapor and some liquid water DU. After adsorption and saturation, DAO could be resurrected by removing water by heating at about 175-315℃. Adsorption and resurrection can take place 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. It can also be used as catalyst, catalyst carrier and chromatographic analysis carrier.
Activated alumina belongs to the category of chemical alumina, which is mainly used as adsorbent, water purifier, catalyst and catalyst carrier. According to different USES, its raw materials and preparation methods are different.
Activated alumina under certain operating conditions and the regeneration conditions, the drying depth up to dew point temperature of the product - 70 degrees, the activated alumina use  : this product can be used as a high fluoride drinking water fluoride agent (fluoride in large capacity), recycling paraffins in alkylbenzene production of fluorine remover, transformer oil acid regeneration agent, used as oxygen gas drying industry, textile industry, electronics industry, automation instrument air drying and desiccant in industries such as chemical fertilizers, petroleum and chemical drying agent (up to 40 degrees -) dew point, dew point pressure swing adsorption (psa) in air separation industry can reach to 55 degrees. It is a kind of highly efficient desiccant with deep dry trace water. Very suitable for non - thermal regeneration unit.
