3A Molecular Sieve

Product Application

HYD03C is specially manufactured for the deep dehydration of olefin cracked gas streams and can selectively remove water. This dehydration process allows olefins to be further processed into petrochemical intermediates or plastics such as polypropylene. This molecular sieve offers low levels of olefin co-adsorption while maintaining a superior coking tolerance and attrition resistance.

  • • used for the deep dehydration of olefin cracked gas
  • • capable of removing water to meet specification
  • • allows ethylene to be used in other petrochemical processes
  • • offers low co-adsorption while maintaining physical strength
Chemical Formula

(Y)a x [(AlO2)a(SiO2)b] x cH2O   (Y = Na, K)



industries used:

bulk dehydration, refrigerant drying, dehydration of unsaturated hydrocarbons, desiccant dryers, static drying, power transformers breathers, water removal


As an adsorbent, molecular sieve should not be left exposed to open air and should be stored in dry conditions with air-proof packaging. This product should not be exposed to temperatures exceeding 230˚C (450˚F).
