Molecular Sieve 5A is an alkali alumino silicate; it is the calcium
form of the Type A crystal structure. Type 5A has an effective pore
opening of5 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 adsorber 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
