Molecular Sieve 5A

La description

Typical Chemical Formula 0.7 CaO . 0.3 Na2O . Al2O3 . 2 SiO2 . 4.5H2O SiO2 : Al2O3 ≈2 Application 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 minimising COS formation. Light mercaptans are also adsorbed. It is also used for the separation of normal- and iso paraffins. Production of high purity N2, O2, H2 and inert gases from mixed gas streams. Regeneration XINTAO 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 ******0�C is required. A properly regenerated molecular sieve can give moisture dew points below ***0�C, or mercaptan or CO2 levels below 2 ppmv. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process. Size 5A - Zeolites are available in beads of **2 mm, (*0x*8 mesh) **3 mm, (8x*2 mesh) , 2.**5 mm, (4x8 mesh) and as powder, and in pellet 1.6”, 3.2”. Attention To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
