  Molecular Sieve 5A  Introduction
GBT Molecular Sieve type 5A is an alkali alumino 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 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 concentrators.
