Product introduction
Molecular Sieve 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 (C4 to C6 species), in PSA hydrogen purification and in oxygen concentrators.
Molecular formula: 0.70CaO·0.30Na2O·Al2O3·2.0SiO2·4.5H2O
Regeneration
Xuefeng 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 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 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh) , 2.5-5 mm, (4x8 mesh) and as powder, and in pellet 1.6, 3.2.

Scope of application
This kind of sieve absorbs substances at the molecular level. It can absorb up to 22% of its body weight. The adsorption principle is similar to that of chromatography, except that the molecular composition of the substance is not changed.
1. Natural gas drying, desulfurization, and carbon dioxide removal;
2. Separation of nitrogen and oxygen, separation of nitrogen and hydrogen to produce oxygen, nitrogen and hydrogen;
3. Petroleum dewaxing, separation of normal hydrocarbons from branched hydrocarbons and cyclic hydrocarbons.
Store
Storage: Room temperature, relative humidity not more than 90%; not directly exposed to the air; avoid water, acid and alkali.
Packing: cardboard drum or carton packaging.
Note: Avoid direct exposure of molecular sieve to air.
