Product Description
YAMTOP Molecular Sieve type 5A is an alkali alumina silicate; it is the calcium form of the Type A crystal structure. 5A Molecular Sieve 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.Get an immediate quote from 5A Molecular Sieve Exporter.

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. |

Regeneration:
YAMTOP molecular sieve Type 5A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. To remove moisture from a 5A molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -70°C, or mercaptans or CO2 levels below 2 ppm.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
The lifetime of 5A Molecular Sieve
The life of a 5A Molecular Sieve, in fact, has a great relationship with our daily use, because the temperature, humidity and dust in the air will poison the molecular sieve, thus reducing the adsorption capacity. Therefore, we should pay attention to the indoor environment when we use it at ordinary times. We should clean the primary filter every week and replace the secondary filter for about 1000 hours to avoid mixing dust into the 5A Molecular Sieve. Similarly, do not use it in excessively humid environments. For example, the bathroom and toilet are too humid.
Size:
5A - Zeolite are available in beads of 2-3 mm(8x12 mesh), 2.5-5 mm(4x8 mesh) and as powder.
Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
