Product Introduction
Guangdong Xintao Molecular Sieve type 5A is an alkali alumina silicate; it is the calcium form of the Type A crystal structure. Type 5A has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.It is especially suitable for PSA adsorption applications where it may be used for the separation of normal- and iso- paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygen concentrators.
Specific Application：
Normal paraffin separating process; Refining SF6 refrigerant for power (removing moisture and hydrocarbon); Oxygen/hydrogen PSA (Pressure Swing Adsorption) process etc.

Typical Application |
a) The strong ionic forces of the divalent calcium ion makes it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while mini missing COS formation. Light mercaptans are also adsorbed. |
