5A Molecular Sieve is a synthetic crystalline aluminosilicate with a regular micropore structure.; 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.
Petrotat 5A Molecular Sieve is commonly used for drying and desulphurization (H2S) of natural gas, for the manufacture of protective gases and for the removal of CO2. PETROTAT 5A Molecular Sieve is also used for the separation of normal paraffins from branched and cyclic hydrocarbons.
Our 5A Molecular Sieve is used for the selective adsorption and separation of polar molecules from mixtures with adsorbable but less polar molecules (e.g. preferred adsorption of H2S in presence of CO2).

5A Molecular Sieve, which is also called zeolite 5A, is one of the types of aluminosilicate crystals with average pores of 5 angstroms (0.5 nm). Molecules with a diameter less than 5 angstroms are absorbed by zeolite 5A. 5A Molecular Sieve is usually used to separate isoparaffins, remove water, carbon dioxide, and hydrogen sulfide from natural gas.
The 5A Molecular Sieve can be regenerated by the TSA thermal method at 250-300 degrees Celsius or by reducing the pressure in the PSA process.If the 5A Molecular Sieve is properly regenerated, it can reach a dew point below -100 degrees Celsius and create a level of mercaptan or CO2 less than ppm2.5A Molecular Sieve should not be exposed to the open air and should be stored in dry conditions and in proper airtight packaging.
