3A molecular sieve is mainly used to adsorb water, and does not adsorb any molecule with diameter greater than 3a. According to the industrial application characteristics, our molecular sieve has the advantages of good adsorption capacity, high crushing strength, multiple regeneration times, strong anti pollution ability, high utilization efficiency, long service life and so on. This product is the first choice desiccant for deep drying, refining and polymerization of gas-liquid phase in petroleum and chemical industry.
