13X-As Molecular Sieve 13X-As

Molecular sieve is a crystallized aluminosilicate. With homogeneous pore size and high specific surface area, Molecular sieve

Molecular sieveis a crystallized aluminosilicate. With homogeneous pore size and high specific surface area, 

Molecular sieve bears excellent features as follows: For small polarity molecules and unsaturated molecules, the higher degree of saturation and polarity, the stronger selective adsorption is; Strong water absorption. Even under high temperature and low moisture content, Molecular sieve still have very high absorption capacity.

Typical products: 3A,4A,5A,10X,13X and copper sieve etc.

Typical Application 1) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien) 2) Cracked Gas Drying3) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required. 4) Drying of highly polar compounds, such as methanol and ethanol5) Drying of liquid alcohol

6) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.7) Drying of refrigerants

 RegenerationMolecular sieve Type 3A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. To remove moisture from a 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.

AttentionTo avoid damp and pre-adsorption of organic before running, or must to be reactivated.
