China Supplier Dental Calcium Hydroxide - Molecular Sieve 5A – Ton Year Detail:

Introduction
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 (C4to C6 species), in PSA hydrogen purification and in oxygen concentrators.

Typical Chemical Formula	0.7CaO. 0.3Na₂O. Al₂O₃. 2SiO₂. 4.5H₂O SiO₂ : Al₂O₃≈2
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. b) Separation of normal- and iso paraffin’s. c) Production of high purity N₂, O₂, H₂ and inert gases from mixed gas streams d) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.

Size Regeneration
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 -100°C, or merca ptan 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.

5A – Zeolites are available in beads of 1-2 mm(10×18 mesh), 2-3 mm(8×12 mesh), 2.5-5 mm(4×8 mesh) and as powder, and in pellet 1.6mm, 3.2mm.

Attention
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
