  2. Molecular Sieve
     The molecular sieve adsorbent is known for fast adsorption speed, recycle usage, high crushing strength, anti-contamination, long service life and high efficiency. A wide application of the molecular sieve is found in petroleum industry and chemical industry for deep drying, refining and polymerizing gases and liquids.

  2. Activated Alumina
     Activated alumina adsorbent has many capillary channels and provides a large surface area. It most often functions as adsorbents, drying agents and catalysts. The activated alumina will not soften, swell, pulverize and crack in water. The defluorination method of activated alumina desiccant is similar to anion exchange resin.
