Molecular sieve is a crystallization of silicon aluminium salts,due to its uniform aperture and high surface, so has many excellent features:
1. Adsorb according to the size and shape of the different aperture, i.e. only adsorb those small apertures,which have sameer size and shape of the molecular sieve;
2. For small polarity molecules and unsaturated molecules, the higher the degree of saturation and polarity, the selective absorption is more stronger;
3. Strong water absorption, even at high temperature, low water content situation , they still have quite high absorption capacity.
Its main types are 3A、4A、5A、10X、13X and copper sieve etc.
The product of other specifications can be prepared according to customer's requirment.
3A:Drying agent for pyrolysis gas and alkene
4A:Drying agent for natural gas and absorbent for paraffin separation.
5A:Dehydration,desulfurization and purification of air natural gas and oil,in oxygen making and hydrogen making by PSA processes.
10X:High-pow absorbents for removal of H2O,H2S,and SO2 in liquid and gas ,as well as for paraffin separation.
13X:Dry and desulfurization and purification for oil and gas.
