English Name: 3A Molecular Sieve Chemical Formula: 2/3K2O·1/3Na2O·Al2O3·2SiO2·9/2H2O
Silicon-to-Aluminum Ratio: SiO₂/Al₂O₃ ≈ 2 Executive Standard: GB/T10504-2017
3A molecular sieve specialty product, with a pore size of approximately 3Å, is suitable for drying gases and liquids as well as dehydrating hydrocarbons. It can be widely used in the deep drying of petroleum, cracked gas, ethylene, propylene, and natural gas, as well as a desiccant for insulating glass.
Main Application Areas
1. Drying of various liquids (such as ethanol)
2. Drying of air and refrigerant
3. Drying of natural gas and methane gas
4. Drying of unsaturated hydrocarbons, as well as cracking gas, ethylene, acetylene, propylene, and butadiene
