Zeolite Molecular Sieve 5A deciccant

Composition 0.80 CaO : 0.20 Na2O : 1 Al2O3: 2.0 ± 0.1 SiO2: x H2O

Description Divalent calcium ions in place of sodium cations give apertures of ~5A which exclude molecules of effective diameter >5A, e.g., all 4-carbon rings, and iso-compounds.

Major Applications Separation of normal paraffins frombranched-chain and cyclic hydrocarbons; removal of H2S, CO2 and mercaptans from natural gas. Molecules adsorbed include nC4H10, nC4H9OH, C3H8 to C22H46, and dichlorodifluoro-methane

The effective pore opening is 5 Angstrom.It is used for the separation for n-and i-paraffin, removal of acid gas,removal of water and CO2.


More Detailed:

Synonym: Zeolite 5A, Molsive 5A, 5A molecular sieve, 5 angstrom sieve

Typical Chemical Formula: Ca4,5 [(Al02)12(SiO2)12].nH2O

CAS NO.: 1318-02-1

Silica-alumina ratio: SiO2/ Al2O3≈2



1. Molecular sieve 5A is an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while decreasing COS formation

2. Molecular sieve 5A can adsorb light mercaptans

2. Molecular sieve 5A also use for the separation of normal- and iso-paraffins

3. Molecular sieve 5A can use for high purity N2, O2, H2 and inert gases from mixed gas streams



Keep 5A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.



Molecular sieve 5A can be regenerated or activated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 5A molecular sieve, a temperature of 200-230℃ (390-570℃)is required. Molecular sieve 5A can also be regnerated or activated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated or activated molecular sieve can give moisture dew points below -100℃. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
