Descripción del producto

XINTAO Molecular Sieve type 4A is an alkali alumina silicate, it is the sodium form of the type Acrystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms(0.4nm). XINTAO tyoe 4A molecular will absorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such as absorbable molecules include simple gas oxygen, nitrogen, carbon dioxyde and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.

Typical Chemical Formula

Na2O. Al2O3. 2SiO2. 4.5 H2O

SiO2 : Al2O3 ≈2

Application

1)Drying and removing of CO2 from natural gas, LPG, air, inert and atmosphere gases, ect.

2) Removal of hydrocarbon, ammonia and methanol from gas streams(ammonia syn gas treating)

3)Special types are used in the air brake units of buses, trucks and locomotives

4)Packed in small bags, it may be used simply as a packaging desiccant

Regeneration

XINTAO molecular sieve 4A can be regenerated by either heating in the case of thermall swing proccess; or by lowering the pressure in the case of pressure swing processes.

size

4A-Zeolite are available in beads of **2mm, (*0**8 mesh)**3mm, (8**2 mesh), 2.**5mm, (4*8 mesh) and sa powder, and in pellet 1.6'', 3.2''

Attention

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